C# WPF: Insert Shape Into TextBlock

I am looking to insert a coloured square (with a border) into a TextBlock in WPF. The colour of the square needs to be set dynamically, and so ideally this should happen in the code-behind, not XAML.
I'm guessing the best way to do this is with a InlineUIContainer, but I can't work out how to position a Rectangle such that it aligns with the text, and is sized appropriately to the font size.
So far I have:
Color myColor = GetMyColor();
TextBlock textBlock = new TextBlock();
textBlock.Inlines.Add(new Run("My color: "));
// Attempt with a Canvas and Rectangle
Canvas canvas = new Canvas();
canvas.Children.Add(new Rectangle() { Height = 6, Width = 6, Fill = new SolidColorBrush(color.Value) });
textBlock.Inlines.Add(new InlineUIContainer(canvas));
// Hacky version that looks terrible
textBlock.Inlines.Add(new Run(" ") { Background = new SolidColorBrush(myColor) });
The problem here is that the Rectangle is created from the text baseline, hanging down. I would like it to be vertically centred relative to the text, square (i.e. aspect ratio of 1), and ideally automatically sized to the font size.
I'd wondered if a Viewbox was somehow useful, or some combination of VerticalAlignment properties, but I couldn't make them work. Any suggestions would be greatly appreciated.

Depending on the size of square you want, you could try using unicode characters 0x25A0 or 0x25AA.
Here's an example defined in Xaml, but you could achieve the same effect in code behind too.
<TextBlock FontFamily="Segoe UI">
<Run Text="ABC" />
<Run Foreground="Red" Text="■" />
<Run Foreground="Green" Text="▪" />
</TextBlock>
<TextBlock FontFamily="Tahoma">
<Run Text="ABC" />
<Run Foreground="Red" Text="■" />
<Run Foreground="Green" Text="▪" />
</TextBlock>
Note that different font families render these characters with different proportion compared to the hight of the regular letters.

You can use a ContentControl and a DataTemplate.
A UserControl or custom Control or ContentControl is also a good solution, especially if you like to add a behavior.
The following example uses a ContentControl and a DataTemplate to display a centered Rectangle next to a text, where the shape's color and the text are dynamic values. The size of the shape is relative to the FontSize applied to the ContentControl.
The final size of the shape can be adjusted by setting a Margin on the Viewbox or by attaching a IValueConverter to the Height binding of the Viewbox:
MainWindow.xaml
<Window>
<Window.Resources>
<DataTemplate x:Key="DataModelTemplate"
DataType="{x:Type DataModel}">
<DockPanel HorizontalAlignment="{Binding RelativeSource={RelativeSource AncestorType=ContentControl}, Path=HorizontalContentAlignment}">
<TextBlock x:Name="TextLabel"
FontSize="{Binding RelativeSource={RelativeSource AncestorType=ContentControl}, Path=FontSize}"
Text="{Binding TextValue}"
VerticalAlignment="Center" />
<Viewbox Height="{Binding ElementName=TextLabel, Path=ActualHeight}"
Margin="8"
Stretch="Uniform">
<Rectangle Width="10"
Height="10"
Fill="{Binding Color}" />
</Viewbox>
</DockPanel>
</DataTemplate>
</Window.Resources>
<StackPanel>
<ContentControl x:Name="TextControl1"
ContentTemplate="{StaticResource DataModelTemplate}"
FontSize="50" />
<ContentControl x:Name="TextControl2"
ContentTemplate="{StaticResource DataModelTemplate}"
FontSize="20" />
</StackPanel>
</Window>
MainWindow.xaml.cs
partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
this.TextControl1.Content = new DataModel("#Test 1", Brushes.Yellow);
this.TextControl2.Content = new DataModel("#Test 2", Brushes.Red);
}
}
DataModel.cs
class DataModel : INotifyPropertyChanged
{
public DataModel(string textValue, Brush color)
{
this.TextValue = textValue;
this.Color = color;
}
public string TextValue { get; }
public Brush Color { get; }
}

Assign Button color during creation of button (runtime)

First I want to appologize for so much code, but English is not my native language so I put as much details as I could, and hope that you will understand what my problem is.
Also I just started learning C# 20 days ago so my error will probably be some basic newbie error :)
Anyway, I have WPF form with few Grids, and in one of the Grid there is:
<Grid Grid.Column="2" Grid.Row="1" Name="grdPLUPanel" >
<ItemsControl x:Name="btnPLUList">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<UniformGrid Columns="4" Margin="0"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button Content ="{Binding Content}" Height="{Binding Height}" Width="{Binding Width}" Tag="{Binding Tag}" Margin="{Binding Margin}" Background="{Binding Color}" FontSize="{Binding FontSize}" FontWeight="Medium" HorizontalAlignment="Center" Click="ClickHandlerGrp" />
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
All of those Bindings Works perfectly except for Background="{Binding Color}".
Code for assigning color which I am getting from database as int (ie. -32768), then converting to Hex(#FFFF8000) and adding to the Background is:
if (dictPLU.ContainsKey(Convert.ToString(i)))
{
GetPLURowsFromDB.MyObject valuePLU = dictPLU[Convert.ToString(i)];
byte[] bytes = BitConverter.GetBytes(valuePLU.btnColor);
var newColor = new SolidColorBrush(Color.FromArgb(bytes[3], bytes[2], bytes[1], bytes[0]));
btns.Add(new TodoItem() { Content = valuePLU.btnContent, Height = btnMinimumHeightSize, Width = btnMinimumWidthSize, FontSize = fntSize, Tag = valuePLU.btnPLUID, Background = newColor, Margin = "1," + separationX + ",0,0" });
}
else
{
btns.Add(new TodoItem() { Content = "", Height = btnMinimumHeightSize, Width = btnMinimumWidthSize, Tag = "PLU" + Convert.ToString(i), Margin = "1," + separationX + ",0,0" });
}
Above code doesn't work, also there are no errors, Button Background simply does not change.
When debugging:
newColor is (#FFFF8000)
valuePLU is (-32768)
Background is {#FFFFFFFF} - a default color assigned automatically when buttons are created.
However if i put Button (btnRcptESC) manually on the form, and use following code:
private void MainWindowView_OnLoaded(object sender, RoutedEventArgs e)
{
byte[] bytes = BitConverter.GetBytes(Convert.ToInt32("-32768"));
var colorNew = new SolidColorBrush(Color.FromArgb(bytes[3], bytes[2], bytes[1], bytes[0]));
btnRcptESC.Background = colorNew;
}
Button Will Change Color.
I am suspecting that problem is in Constructor "public SolidColorBrush Background { get; set; }"
Maybe SolidColorBrush is not proper type?

I've figured out, the problem was in XAML (Background="{Binding Color}" ) and Constructor (public SolidColorBrush Background { get; set; }).
For this to work correctly, in XAML should be (Background="{Binding Background})"
As I said, this is probably noob error :)
Thank you all!

how to change the image style received from webservice in windows phone 7

I am sharing the screen shot of my application. The image which is coming i want it to be in the side and should be small in size. Here i am not getting the full image also. Can anyone help me to fit the image in the listbox and appear it in the side.
My xaml code is:
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<ListBox Name="listBox1">
<ListBox.ItemTemplate>
<DataTemplate>
<Button>
<Button.Content>
<ScrollViewer HorizontalScrollBarVisibility="Auto" Height="80" Width="400">
<!--<ScrollViewer Height="80">-->
<StackPanel Orientation="Horizontal" Margin="0,0,0,0">
<StackPanel Orientation="Vertical" Height="80">
<TextBlock Text="{Binding Path=News_Title}" TextWrapping="Wrap" ></TextBlock>
<TextBlock Text="{Binding Path=News_Description}" TextWrapping="Wrap"></TextBlock>
<TextBlock Text="{Binding Path=Date_Start}" TextWrapping="Wrap"></TextBlock>
<Image Source="{Binding ImageBind }" />
</StackPanel>
</StackPanel>
</ScrollViewer>
</Button.Content>
</Button>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
My .cs code is:
public class Newss
{
public string News_Title { get; set; }
public string News_Description { get; set; }
public string Date_Start { get; set; }
public string image_path { get; set; }
public BitmapImage ImageBind{get;set;}
}
public News()
{
InitializeComponent();
KejriwalService.aapSoapClient client = new KejriwalService.aapSoapClient();
client.getarvindNewsCompleted += new EventHandler<KejriwalService.getarvindNewsCompletedEventArgs>(client_getarvindNewsCompleted);
client.getarvindNewsAsync();
}
void client_getarvindNewsCompleted(object sender, KejriwalService.getarvindNewsCompletedEventArgs e)
{
string result = e.Result.ToString();
List<Newss> listData = new List<Newss>();
XDocument doc = XDocument.Parse(result);
foreach (var location in doc.Descendants("UserDetails"))
{
Newss data = new Newss();
data.News_Title = location.Element("News_Title").Value;
//data.News_Description = location.Element("News_Description").Value;
data.Date_Start = location.Element("Date_Start").Value;
data.image_path = location.Element("image_path").Value;
data.ImageBind = new BitmapImage(new Uri( #"http://political-leader.vzons.com/ArvindKejriwal/images/uploaded/"+data.image_path, UriKind.Absolute));
listData.Add(data);
}
listBox1.ItemsSource = listData;
}

Try to move your Image outside inner StackPanel :
.....
<StackPanel Orientation="Horizontal" Margin="0,0,0,0">
<StackPanel Orientation="Vertical" Height="80">
<TextBlock Text="{Binding Path=News_Title}" TextWrapping="Wrap" ></TextBlock>
<TextBlock Text="{Binding Path=News_Description}" TextWrapping="Wrap"></TextBlock>
<TextBlock Text="{Binding Path=Date_Start}" TextWrapping="Wrap"></TextBlock>
</StackPanel>
<Image Source="{Binding ImageBind }" />
</StackPanel>
.....
That will make the Image appear besides the Text. Then try to set Width and Height properties of Image control to fixed value, and set Stretch property appropriately. See this post for reference about setting Stretch property.

There're too many wrong things here, and I don't know what you want.
You've put buttons inside items of ListBox. You should either remove buttons and rely on listbox own items selection mechanism for handling touch elents, or continue using buttons but replace ListBox with ItemsControl that doesn’t handle touch.
You’ve put ScrollViewer inside those buttons. So if you have 10 items, you’ll have 10 buttons, each with its own scroll viewer. Why you did that?
You’ve set height of your StackPanel to 80. When specifying fixed height, Silverlight often does not care whether the content fits or no, instead it clips things. It’s rarely a good idea to specify absolute size of elements.
Instead of using two nested stack panels, you should use single Grid with two rows and two columns, where image occupies both rows of the second column (using Grid.RowSpan property).
And you’re asking question about changing image style? You should fix the rest of your XAML first…

How to bind data to a ListBox in a ControlTemplate?

What I am trying to do is to create some sort of "rooms"(like a chat group, a sharing center or whatever you want). All the room are created the same way, but each one of them contains different informations. Each of these rooms is contained in a TabItem. I managed to create dynamically all the Tabitems, to give those a Grid and a Canvas. But at the moment I am facing a problem: I created a ControlTemplate Called RoomMenu that will show different buttons and, the most important, the people connected in this room in a ListBox(I retrieve those people from a WebService each time I change the selected Tabitem). But since my ListBox is in a ControlTemplate I have no idea how to access the ListBox ItemSource to bind a generic List to it. Down Below is the code used to create my rooms and their content.
Here is my room menu class:
public class RoomMenu : ContentControl
{
public RoomMenu()
{
DefaultStyleKey = typeof(RoomMenu);
}
public string Current_room_id;
public string FullName;
public string Rights;
}
And here is the ControlTemplate located in generic.xaml:
<Style TargetType="test:RoomMenu">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="test:RoomMenu">
<Grid x:Name="MenuGrid">
<Border HorizontalAlignment="Stretch" VerticalAlignment="Stretch" BorderBrush="Black" CornerRadius="2" Background="Black">
<StackPanel Orientation="Vertical">
<Border x:Name="Room_friend_border" Background="Gray" CornerRadius="4" Margin="5">
<ListBox x:Name="current_room_friends" ItemsSource="{Binding ''}" Margin="5" Height="230">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding FullName}" Height="20"/>
<TextBlock Text="{Binding Rights}" Height="20"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Border>
<Border x:Name="Room_menu" Background="Gray" CornerRadius="4" Margin="5">
<StackPanel Orientation="Vertical" Margin="10">
<Button Content="Add item" Margin="0,2,0,2"/>
<Button Content="Set changes" Margin="0,2,0,2"/>
<Button Content="Invite friend" Margin="0,2,0,2"/>
<Button Content="Rename room" Margin="0,2,0,2"/>
<Button Content="Delete room" Margin="0,2,0,2"/>
</StackPanel>
</Border>
</StackPanel>
</Border>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Here is my Dictionnary Class that contains the RoomMenu:
public class Rooms : TabItem
{
public string Room_guid;
public string Room_name;
public string Primary_user_guid;
public string Room_version;
public Grid Room_grid;
public Canvas Room_canvas;
public RoomMenu Room_menu;
}
And this is when I call my ControlTemplate and Add it to my TabItem's Grid:
public void Set_rooms_interface()
{
foreach (KeyValuePair<string, Rooms> kvp in rooms_list)
{
rooms_list[kvp.Key].Room_menu = new RoomMenu();
rooms_list[kvp.Key].Room_canvas = new Canvas();
rooms_list[kvp.Key].Room_grid = new Grid();
//instance grid columns
rooms_list[kvp.Key].Room_grid.ColumnDefinitions.Add(new ColumnDefinition() {Width = new GridLength(900)});
rooms_list[kvp.Key].Room_grid.ColumnDefinitions.Add(new ColumnDefinition());
//Refreshing room canvas
rooms_list[kvp.Key].Room_canvas.Height = rooms_list[kvp.Key].Room_grid.ActualHeight;
rooms_list[kvp.Key].Room_canvas.Width = rooms_list[kvp.Key].Room_grid.ActualWidth;
rooms_list[kvp.Key].Room_canvas = refresh_canvas(kvp.Key);
Grid.SetColumn(rooms_list[kvp.Key].Room_canvas, 0);
Grid.SetColumn(rooms_list[kvp.Key].Room_menu, 1);
//Add Canvas to Grid
rooms_list[kvp.Key].Room_grid.Children.Add(rooms_list[kvp.Key].Room_canvas);
rooms_list[kvp.Key].Room_grid.Children.Add(rooms_list[kvp.Key].Room_menu);
//Setting TabItem Name
rooms_list[kvp.Key].Header = rooms_list[kvp.Key].Room_name;
//Adding Grid to TabItem.Content
rooms_list[kvp.Key].Content = rooms_list[kvp.Key].Room_grid;
//Adding TabItem to TabControl
Room_tab.Items.Add(kvp.Value);
}
}
I'm sorry if the whole question is a bit long but it was the only way to explain clearly what I was trying to do. So if anyone could give me a hint or answer to do some databinding in a ControlTemplate it would greatly help me.
Thank You.

I think you started in the wrong direction when instantiating UI elements in code. The code behind should only contain one line assigning the people list to the current_room_friends DataContext.
Start with simpler examples of binding data to a ListBox like the beautiful planet example of Bea Stollnitz.

Vertical Text in Wpf TextBlock

Is it possible to display the text in a TextBlock vertically so that all letters are stacked upon each other (not rotated with LayoutTransform)?

Nobody has yet mentioned the obvious and trivial way to stack the letters of an arbitrary string vertically (without rotating them) using pure XAML:
<ItemsControl
ItemsSource="Text goes here, or you could use a binding to a string" />
This simply lays out the text vertically by recognizing the fact that the string is an IEnumerable and so ItemsControl can treat each character in the string as a separate item. The default panel for ItemsControl is a StackPanel, so the characters are laid out vertically.
Note: For precise control over horizontal positioning, vertical spacing, etc, the ItemContainerStyle and ItemTemplate properties can be set on the ItemsControl.

Just in case anybody still comes across this post... here is a simple 100% xaml solution.
<TabControl TabStripPlacement="Left">
<TabItem Header="Tab 1">
<TabItem.LayoutTransform>
<RotateTransform Angle="-90"></RotateTransform>
</TabItem.LayoutTransform>
<TextBlock> Some Text for tab 1</TextBlock>
</TabItem>
<TabItem Header="Tab 2">
<TabItem.LayoutTransform>
<RotateTransform Angle="-90"></RotateTransform>
</TabItem.LayoutTransform>
<TextBlock> Some Text for tab 2</TextBlock>
</TabItem>
</TabControl>

I don't think there is a straighforward of doing this withought changing the way the system inherently laysout text. The easiest solution would be to change the width of the textblock and supply a few extra properties like this:
<TextBlock TextAlignment="Center" FontSize="14" FontWeight="Bold" Width="10" TextWrapping="Wrap">THIS IS A TEST</TextBlock>
This is hacky, but it does work.

Just use a simple LayoutTransform..
<Label Grid.Column="0" Content="Your Text Here" HorizontalContentAlignment="Center">
<Label.LayoutTransform>
<TransformGroup>
<RotateTransform Angle="90" />
<ScaleTransform ScaleX="-1" ScaleY="-1"/>
</TransformGroup>
</Label.LayoutTransform>
</Label>

It's doable:
Your TextBlock's TextAlignment property should be set to Center:
<TextBlock Name="textBlock1" TextAlignment="Center" Text="Stacked!" />
Then add NewLines between every character:
textBlock1.Text =
String.Join(
Environment.NewLine,
textBlock1.Text.Select(c => new String(c, 1)).ToArray());
(Uses System.Linq to create an array of strings from the individual characters in the original string. I'm sure there are other ways of doing that...)

Below XAML code changes the angle of text displayed in a textblock.
<TextBlock Height="14"
x:Name="TextBlock1"
Text="Vertical Bottom to Up" Margin="73,0,115,0" RenderTransformOrigin="0.5,0.5" >
<TextBlock.RenderTransform>
<TransformGroup>
<ScaleTransform/>
<SkewTransform/>
<RotateTransform Angle="-90"/>
<TranslateTransform/>
</TransformGroup>
</TextBlock.RenderTransform>
</TextBlock>

the accepted answer suggested by Ray Burns does not work for me on .net 4.0. Here is how I did it:
pull in the mscorlib
xmlns:s="clr-namespace:System;assembly=mscorlib"
put in your usercontrol/window/page resources
<s:String x:Key="SortString">Sort</s:String>
and use it like this
<ItemsControl ItemsSource="{Binding Source={StaticResource SortString}}" Margin="5,-1,0,0" />
hope it helps!

create a stackpanel with a bunch ot textblocks that take one char

make the text container's max width to allow for one char only and wrap the text:
<TextBlock TextWrapping="Wrap" MaxWidth="8" TextAlignment="Center" Text="stack" />

Make an image and fill the block with the image, use photoshop or something designed to manipulate text instead of fiddling in code ?

This code allows to have vertical text stacking and horizontal centered letters.
<ItemsControl Grid.Row="1"
Grid.Column="0"
ItemsSource="YOUR TEXT HERE"
HorizontalAlignment="Center"
VerticalAlignment="Center">
<ItemsControl.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding}"
HorizontalAlignment="Center"/>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>

Here's a way to insert a '\n' after every character in the text of the TextBlock, that way making it display vertically:
<TextBlock x:Name="VertTextBlock" Text="Vertical Text" Loaded="VertTextBlock_Loaded"></TextBlock>
Then, in the Loaded event handler, you say:
TextBlock tb = sender as TextBlock;
StringBuilder sb = new StringBuilder(tb.Text);
int len = tb.Text.Length * 2;
for (int i = 1; i < len; i += 2)
{
sb.Insert(i, '\n');
}
tb.Text = sb.ToString();
That solution was proposed by Lette, but I believe my implementation incurs less overhead.

<linebreak/> can be used to show data in two lines

You could also use the "RUN" binding
In the App.xaml file use something like this:
<Application x:Class="Some.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:commands="clr-namespace:Deridiam.Helper.Commands"
xmlns:i="http://schemas.microsoft.com/xaml/behaviors"
ShutdownMode="OnMainWindowClose"
StartupUri="Views/MainWindow.xaml">
<Application.Resources>
<commands:HorizontalToVertical x:Key="HorizontalToVertical_Command"></commands:HorizontalToVertical>
<ControlTemplate x:Key="VerticalCell" TargetType="ContentControl">
<TextBlock Text="{TemplateBinding Content}" Foreground="Black"
TextAlignment="Center" FontWeight="Bold" VerticalAlignment="Center"
TextWrapping="Wrap" Margin="0" FontSize="10">
<i:Interaction.Triggers>
<i:EventTrigger EventName="Loaded">
<i:InvokeCommandAction Command="{Binding ConvertToVerticalCmd, Source={StaticResource HorizontalToVertical_Command}}"
CommandParameter="{Binding RelativeSource={RelativeSource AncestorType={x:Type TextBlock}}}" />
</i:EventTrigger>
</i:Interaction.Triggers>
</TextBlock>
</ControlTemplate>
</Application.Resources>
Create the command class binded to the textblock using i:Interaction.Triggers on the Loaded event in the app.xaml example
namespace Deridiam.Helper.Commands
{
public class HorizontalToVertical
{
private ICommand _convertToVerticalCommand;
public ICommand ConvertToVerticalCmd =>
_convertToVerticalCommand ?? (_convertToVerticalCommand = new RelayCommand(
x =>
{
var tBlock = x as TextBlock;
var horizontalText = tBlock.Text;
tBlock.Text = "";
horizontalText.Select(c => c).ToList().ForEach(c =>
{
if (c.ToString() == " ")
{
tBlock.Inlines.Add("\n");
//tBlock.Inlines.Add("\n");
}
else
{
tBlock.Inlines.Add((new Run(c.ToString())));
tBlock.Inlines.Add(new LineBreak());
}
});
}));
}
}
Finally in the .xaml file where you want the vertical text to be shown
<ContentControl Width="15" Content="Vertical Text" Template="{StaticResource VerticalCell}">
</ContentControl>
Will result in:
Vertical Text

none of the above solutions solved my problem (some come close), so I'm here to post my solution and maybe help someone.
The accepted solution helped me, but the text is not aligned to the center.
<ItemsControl ItemsSource="{Binding SomeStringProperty, FallbackValue=Group 1}" Margin="5"
TextElement.FontSize="16"
TextElement.FontWeight="Bold"
TextBlock.TextAlignment="Center"
HorizontalAlignment="Center"
VerticalAlignment="Center" >
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel Orientation="Vertical" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate >
<TextBlock Text="{Binding }" HorizontalAlignment="Center" />
</DataTemplate>
</ItemsControl.ItemTemplate>

I will offer a solution based on the converter:
using System;
using System.Collections.Generic;
using System.Globalization;
using System.Windows.Data;
using System.Windows.Markup;
namespace Converters
{
[ValueConversion(typeof(object), typeof(string))]
public class InsertLineBreakConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
if (parameter != null)
value = parameter;
if (value == null)
return null;
if (!(value is string str))
str = value.ToString();
return string.Join(Environment.NewLine, (IEnumerable<char>) str);
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
public static InsertLineBreakConverter Instance { get; } = new InsertLineBreakConverter();
}
public class InsertLineBreakConverterExtension : MarkupExtension
{
public override object ProvideValue(IServiceProvider serviceProvider)
=> InsertLineBreakConverter.Instance;
}
}
Usage examples:
<TextBlock Text="{Binding Property, Converter={cnvs:InsertLineBreakConverter}}"/>
<TextBlock Text="{Binding Converter={cnvs:InsertLineBreakConverter}, ConverterParameter='Some Text'}"/>
