I just need to separate two grous of buttons inside StackPanel with something like:
---------Another Buttons--------
but I need a solid line, note --
I made a custom control for this.
The code for the Generic.xaml
<Style TargetType="{x:Type local:LineControl}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type local:LineControl}">
<Border Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition></ColumnDefinition>
<ColumnDefinition Width="Auto"></ColumnDefinition>
<ColumnDefinition></ColumnDefinition>
</Grid.ColumnDefinitions>
<Separator Grid.Column="0" VerticalAlignment="Center"></Separator>
<ContentPresenter Grid.Column="1" Content="{TemplateBinding Content}" VerticalAlignment="Center"></ContentPresenter>
<Separator Grid.Column="2" VerticalAlignment="Center"></Separator>
</Grid>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
The C# code:
public class LineControl : ContentControl
{
static LineControl()
{
DefaultStyleKeyProperty.OverrideMetadata(typeof(LineControl), new FrameworkPropertyMetadata(typeof(LineControl)));
}
}
And you use it like this
<local:LineControl>
<TextBlock>test</TextBlock>
</local:LineControl>
The TextBlock can be any control. You can even put a StackPanel with buttons in it if you want.
<StackPanel Orientation="Horizontal">
<Separator Style="{StaticResource {x:Static ToolBar.SeparatorStyleKey}}" />
</StackPanel>

I'm a newby in WPF, so please exuse if this is a trivial question...
I need to create many similar controls, each of them consists of a picture and a title below. I try this way:
XAML (Style with a template inside of a ResourceDictionary):
<Style x:Key="myStyle" TargetType="{x:Type Button}">
<Setter Property="Width" Value="300"></Setter>
<Setter Property="Height" Value="320"></Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Grid Margin="5 2" Width="{TemplateBinding Width}" Height="{TemplateBinding Height}" Background="White" >
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Image Width="300" Height="250" x:Name="picGraph" Source="picture1.png" />
<TextBlock Grid.Row="1" Text="title1" HorizontalAlignment="Center" />
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
XAML (Usage):
<Button Style="{StaticResource TestGenResultsGraph}"/>
That's all good, but I want to be able to change the Source-property of the image and Text-property of the textblock when I use the Button (to use more than only picture1.png).
I tried to add a setter for a Source-property, but it doesn't work this way, because Button-control doesn't have it:
<Setter Property="Source" Value="picture1.png"/> <!-- Error: The member "Source" is not recognized or is not accessible-->
So generally I would like to have a possibility of usage like that:
<Button Style="{StaticResource myStyle}" Source="picture1.png" Title="title 1"/>
How can I make those properties of children being settable in the parent?
A Button has indeed no Title or Source properties. If you don't want to create your own custom control, you should be able to use the Content and Tag properties:
<Button Style="{StaticResource myStyle}" Tag="picture1.png" Content="title 1"/>
Template:
...
<Image Width="300" Height="250" x:Name="picGraph"
Source="{Binding Tag, RelativeSource={RelativeSource AncestorType=Button}}" />
I have a treeview working, it has a toggle button that can expand it's contents. When I do, each column is too far to the right from where I want it due to the toggle expansion width. I'd like to override that behaviour but I don't know how, I understand it's something to do with defining the control template of the TreeView?
This is my code
c#
Class MyList
{
double someDouble;
double somestring;
souble anotherString;
bool thisOnesABool;
}
Class MyContainer
{
string headerText1;
string headerText2;
List<MyList> SomeList;
}
List<MyContainer> SomeContainerInCodeBehind = new List<MyContainer>();
WPF
<UserControl.Resources>
<DataTemplate x:Key="level2">
<Grid>
//the content of 'MyList'
</Grid>
</DataTemplate>
<HierarchicalDataTemplate x:Key="level1"
ItemsSource="{Binding SomeListWithinContainer}"
ItemTemplate="{StaticResource level2}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="100"/>
<ColumnDefinition Width="100"/>
</Grid.ColumnDefinitions>
<TextBox Grid.Column="0" Text="{Binding HeaderText}" />
<TextBox Grid.Column="1" Text="{Binding MoreHeaderText}" />
</Grid>
</HierarchicalDataTemplate>
</UserControl.Resources>
<Grid>
<TreeView Name="TheTreeView"
Grid.Row="1"
ItemTemplate="{StaticResource level1}"
ItemsSource="{Binding SomeContainerInCodeBehind}">
</TreeView>
</Grid>
In order to change the position of the expander (or expanded child items), you have to override the ControlTemplate of the TreeViewItem.
The following Style is taken from Microsoft Docs: TreeView Styles and Templates and shortened to show the relevant code. Visit the link to get the full code.
<Style x:Key="{x:Type TreeViewItem}"
TargetType="{x:Type TreeViewItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TreeViewItem}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition MinWidth="19"
Width="Auto" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition />
</Grid.RowDefinitions>
<VisualStateManager.VisualStateGroups>
...
</VisualStateManager.VisualStateGroups>
<!-- Use Margin to modify the position of the "Expander" ToggleButton -->
<ToggleButton x:Name="Expander"
Style="{StaticResource ExpandCollapseToggleStyle}"
ClickMode="Press"
IsChecked="{Binding IsExpanded,
RelativeSource={RelativeSource TemplatedParent}}"/>
<Border x:Name="Bd"
Grid.Column="1"
Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}"
Padding="{TemplateBinding Padding}">
<!-- Modify e.g. Margin to change the position of the Header (parent item) -->
<ContentPresenter x:Name="PART_Header"
ContentSource="Header"
HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"/>
</Border>
<!-- Modify e.g. using Margin to reposition the expanded child items -->
<ItemsPresenter x:Name="ItemsHost"
Grid.Row="1"
Grid.Column="1"
Grid.ColumnSpan="2"
Visibility="Collapsed" />
</Grid>
...
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
I have a button in XAML which i styled the way I need it. This is XAML code of that button:
<Button x:Name="btnAddNewItem"
Grid.Column="0" Grid.Row="0"
FontSize="15"
BorderThickness="1.5"
HorizontalContentAlignment="Center"
VerticalContentAlignment="Center"
Foreground="White"
Background="White"
BorderBrush="#0091EA" Margin="5,0,0,0" Height="90" Width="90">
<Button.Template>
<ControlTemplate TargetType="{x:Type Button}">
<Border BorderThickness="{TemplateBinding BorderThickness}"
BorderBrush="{TemplateBinding BorderBrush}"
Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}" />
</Border>
</ControlTemplate>
</Button.Template>
And I would like to achieve something like this, so I would like to delete xaml button, and create same button programatically when its needed, with same style and everything like I did in xaml, example how I would like to create it:
private void AddSubmenuButton(string name)
{
MyButton button = new MyButton();
button.ButtonText = name;
}
Is this possible and if so: how?
P.S I tried classic way, like this:
Button a = new Button();
a.BorderThickness = new Thickness(1);
a.Foreground = new SolidColorBrush(Colors.Black);
a.BorderBrush = mySolidColorBrush;
a.Content = "Button1";
a.Width = 90;
a.Height = 90;
But I get this:
It's possible to notice that thickness it not 1 at all, it has some weird value
and I don't know how to change it.. So that is reason why I created button in xaml which looks much more nice and I want to call it/create it from code behind.
EDIT:
#mm8 THANK YOU A LOT!
THAT'S IT!
This is awesome mate, but what about that If I would like to place icon + text in my button, I would ussualy
add something like this and its fine for me:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="80*">
<RowDefinition Height="20*"/>
</Grid.RowDefinitions>
<Image Source="/MyProject.Wpf;component/Icons/customer-icon.png" Margin="10" Grid.Row="0" Width="Auto"/>
<TextBlock Foreground="Black" Margin="0,0,0,3" Grid.Row="1" VerticalAlignment="Center" HorizontalAlignment="Center" >Izlaz</TextBlock>
</Grid>
as you can see I would add Grid to my button and it would look like this:
<Button x:Name="btnAddNewItem"
Grid.Column="0" Grid.Row="0"
FontSize="15"
ToolTip="Podaci"
BorderThickness="1.5"
HorizontalContentAlignment="Center"
VerticalContentAlignment="Center"
Foreground="White"
Background="White"
BorderBrush="#0091EA" Margin="5,0,0,0" Height="90" Width="90">
<Button.Template>
<ControlTemplate TargetType="{x:Type Button}">
<Border BorderThickness="{TemplateBinding BorderThickness}"
BorderBrush="{TemplateBinding BorderBrush}"
Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}" />
</Border>
</ControlTemplate>
</Button.Template>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="80*">
<RowDefinition Height="20*"/>
</Grid.RowDefinitions>
<Image Source="/MyProject.Wpf;component/Icons/customer-icon.png" Margin="10" Grid.Row="0" Width="Auto"/>
<TextBlock Foreground="Black" Margin="0,0,0,3" Grid.Row="1" VerticalAlignment="Center" HorizontalAlignment="Center" >Izlaz</TextBlock>
</Grid>
</Button>
So could I somehow achieve this (image + text IN MY button ) also to create it programatically.
Define a style in your App.xaml:
<Application x:Class="WpfApplication1.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfApplication1"
StartupUri="MainWindow.xaml">
<Application.Resources>
<Style x:Key="theStyle" TargetType="Button">
<Setter Property="FontSize" Value="15" />
<Setter Property="BorderThickness" Value="1.5" />
<Setter Property="HorizontalContentAlignment" Value="Center" />
<!-- and so on for each property...-->
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border BorderThickness="{TemplateBinding BorderThickness}"
BorderBrush="{TemplateBinding BorderBrush}"
Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Application.Resources>
</Application>
You can then apply this style to any Button in your application, either in XAML:
<Button x:Name="btnAddNewItem" Style="{StaticResource myStyle}"/>
...or programmatically:
Button button = new Button();
button.Style = Application.Current.Resources["myStyle"] as Style;
How to wrap text in GroupBox header? This code doesn't work.
<GroupBox>
<GroupBox.Header>
<TextBlock Text="qwertyuiopasdfghjklqwertyuiopasdfghjkl" TextWrapping="Wrap"/>
</GroupBox.Header>
In-order to get the text content wrapped,You have to specify the width, other wise the with of the textblock automatically set to the length of content in the text block.
<TextBlock Width="150" Text="qwertyuiopasdfghjklqwertyuiopasdfghjkl" TextWrapping="Wrap"/>
While the solution to set the header's width by explicitly specifying the value or binding with another element works perfectly, delving into the default style of GroupBox, I found that making small modifications into the style will solve this issue.
<BorderGapMaskConverter x:Key="BorderGapMaskConverter"/>
<Style TargetType="{x:Type GroupBox}">
<Setter Property="BorderBrush" Value="#D5DFE5"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type GroupBox}">
<Grid SnapsToDevicePixels="True">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="6"/>
<!-- <ColumnDefinition Width="Auto"/> is removed because its Width="Auto" is problematic. -->
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="6"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
<RowDefinition Height="6"/>
</Grid.RowDefinitions>
<!-- The value of Grid.ColumnSpan is changed from 4 to 3. -->
<Border Grid.Column="0" Grid.ColumnSpan="3" Grid.Row="1" Grid.RowSpan="3"
BorderBrush="Transparent"
BorderThickness="{TemplateBinding BorderThickness}"
Background="{TemplateBinding Background}"
CornerRadius="4"/>
<!-- The value of Grid.ColumnSpan is changed from 4 to 3. -->
<Border Grid.ColumnSpan="3" Grid.Row="1" Grid.RowSpan="3"
BorderBrush="White"
BorderThickness="{TemplateBinding BorderThickness}"
CornerRadius="4">
<Border.OpacityMask>
<MultiBinding Converter="{StaticResource BorderGapMaskConverter}"
ConverterParameter="7">
<Binding ElementName="Header" Path="ActualWidth"/>
<Binding RelativeSource="{RelativeSource Self}" Path="ActualWidth"/>
<Binding RelativeSource="{RelativeSource Self}" Path="ActualHeight"/>
</MultiBinding>
</Border.OpacityMask>
<Border BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}"
CornerRadius="3">
<Border BorderBrush="White"
BorderThickness="{TemplateBinding BorderThickness}"
CornerRadius="2"/>
</Border>
</Border>
<!-- HorizontalAlignment="Left" is added to adjust the surrounding line. -->
<Border x:Name="Header"
Grid.Column="1" Grid.Row="0" Grid.RowSpan="2"
HorizontalAlignment="Left"
Padding="3,1,3,0">
<ContentPresenter ContentSource="Header"
RecognizesAccessKey="True"
SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
</Border>
<!-- Grid.ColumnSpan="2" is removed because it is no longer necessary. -->
<ContentPresenter Grid.Column="1" Grid.Row="2"
Margin="{TemplateBinding Padding}"
SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
The root cause of this issue is Width="Auto" of the 2nd ColumnDefinition of Grid. So remove the ColumnDefinition so that the header's Border is assigned to the original 3rd ColumnDefinition. Then add HorizontalAlignment="Left" to the header's Border. Some trivial edits of ColumnSpan. That's it.
This modified style lets WPF's layout engine determine the header's width automatically depending on actual width of GroupBox. No need to care about the width each time. As far as I know, there is no noticeable degradation from the default one.
I am trying to get a border to show around an avalonEdit 'box' in a Wpf control but can't seem to make it happen.
I added BorderBrush="Black" BorderThickness="2" but clearly I am missing something.
I've googled but, despite my endeavors, I cannot find anything - I suspect I may not know the correct terminology to Google for because it feels like it should be straightforward!
Code as follows:
<Label Content="Account:" HorizontalAlignment="Left" Margin="10,28,0,0" VerticalAlignment="Top"/>
<TextBox Name ="textBoxAccount" HorizontalAlignment="Left" Height="23" Margin="66,28,0,0" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="120"/>
<Label Content="Query:" HorizontalAlignment="Left" Margin="10,59,0,0" VerticalAlignment="Top"/>
<Button x:Name="btnGo" Content="Go!" HorizontalAlignment="Left" Height="25" Margin="10,342,0,0" VerticalAlignment="Top" Width="146"/>
<avalonEdit:TextEditor
xmlns:avalonEdit="http://icsharpcode.net/sharpdevelop/avalonedit"
x:Name="textEditor"
FontFamily="Consolas"
SyntaxHighlighting="AWQL"
ScrollViewer.VerticalScrollBarVisibility="Hidden"
WordWrap="True"
Visibility="Visible"
BorderBrush="Black" BorderThickness="2"
FontSize="10pt" Margin="12,89.96,10,0" Height="229" VerticalAlignment="Top"/>
</Grid>
which renders like this:
but the 'avalonEdit' box doesn't seem to render the border so looks invisible unless/until a user clicks inside it and starts typing.
I'd really like the border to look the same as the simple textbox at the top of the user control but right now I'd settle for anything visible!
I only worked once with avalon before so I cooked up a quick project which does what you want.
As a disclaimer, AvalonEdit seems to ruin any attempt to put a border around it like you said. So I set it up using a grid to put a border around it.
It will look something like this:
And the code will look like this:
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Width="600" Height="500"
xmlns:avalonEdit="http://icsharpcode.net/sharpdevelop/avalonedit">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Label Grid.Column="0" Grid.Row="0" Content="Account:" HorizontalAlignment="Left" Margin="20,20" VerticalAlignment="Top" Height="26" Width="56" />
<TextBox Grid.Column="1" Grid.Row="0" Name="textBoxAccount" HorizontalAlignment="Left" Height="26" Margin="20" TextWrapping="Wrap"
VerticalAlignment="Top" Width="120" />
<Label Grid.Column="0" Grid.Row="1" Content="Query:" HorizontalAlignment="Left" Margin="20,0" VerticalAlignment="Top" Height="26" Width="45" />
<Border Grid.ColumnSpan="2"
Grid.Row="2"
Grid.Column="0" BorderBrush="Black" BorderThickness="1"
Margin="20"
Height="230">
<avalonEdit:TextEditor
x:Name="textEditor"
FontFamily="Consolas"
SyntaxHighlighting="AWQL"
ScrollViewer.VerticalScrollBarVisibility="Hidden"
WordWrap="True"
Visibility="Visible"
FontSize="10pt" VerticalAlignment="Top" Height="226"/>
</Border>
<Button Grid.Column="0" Grid.Row="3" x:Name="btnGo" Content="Go!" HorizontalAlignment="Left" Height="25" Margin="20"
VerticalAlignment="Top" Width="146" />
</Grid>
This is not exactly what you want, but a grid will help with other issues as well in the long run
This is the avalonEdit:TextEditor style (TextEditor.xaml):
<Style TargetType="{x:Type AvalonEdit:TextEditor}">
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.WindowTextBrushKey}}" />
<Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.WindowBrushKey}}" />
<Setter Property="FlowDirection" Value="LeftToRight"/> <!-- AvalonEdit does not support RTL, so ensure we use LTR by default -->
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type AvalonEdit:TextEditor}">
<ScrollViewer
Focusable="False"
Name="PART_ScrollViewer"
CanContentScroll="True"
VerticalScrollBarVisibility="{TemplateBinding VerticalScrollBarVisibility}"
HorizontalScrollBarVisibility="{TemplateBinding HorizontalScrollBarVisibility}"
Content="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=TextArea}"
VerticalContentAlignment="Top"
HorizontalContentAlignment="Left"
Background="{TemplateBinding Background}"
Padding="{TemplateBinding Padding}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}"
/>
<ControlTemplate.Triggers>
<Trigger Property="WordWrap"
Value="True">
<Setter TargetName="PART_ScrollViewer"
Property="HorizontalScrollBarVisibility"
Value="Disabled" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
And this is an explanation about why ScrollViewer doesn't show borders: https://social.msdn.microsoft.com/Forums/vstudio/en-US/a2310302-167b-44e2-bc23-825ff1610701/scrollviewer-border
So, I think the best way is to wrap the TextEditor inside a Border as Guerudo says or modify the template in Avalon code TextEditor.xaml.
I didn't work with avalonEdit but I can suggest you an other way : you could wrap your TextEditor inside a <Border> </Border>.
It's probably not the best solution but it is one.
The AvalonEdit community nicely fixed this problem by changing the TextEditor style from the project:
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type AvalonEdit:TextEditor}">
<Border
Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}">
<ScrollViewer
Focusable="False"
Name="PART_ScrollViewer"
CanContentScroll="True"
VerticalScrollBarVisibility="{TemplateBinding VerticalScrollBarVisibility}"
HorizontalScrollBarVisibility="{TemplateBinding HorizontalScrollBarVisibility}"
Content="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=TextArea}"
VerticalContentAlignment="Top"
HorizontalContentAlignment="Left"
Padding="{TemplateBinding Padding}"
/>
</Border>
