I am trying to add user controls to the Grid and I am trying to set the Grid.Column and Grid.Row property in the DataTemplate but it does not have any effect on the rendering. Can someone help to point out what could be wrong in the code below.
I have the main window with the following code:

I am trying to add user controls to the grid and I am trying to set the Grid.Column and Grid.Row property in the data template but it does not have any effect on the rendering
We can't do the attached property binding in a DataTemplate, creating a style for your UserControl in ItemsControl.ItemContainerStyle can make it work:
<ItemsControl ItemsSource="{Binding Controls}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<Grid Name="MainGrid">
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
</Grid>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemContainerStyle>
<Style TargetType="AppControls:TagInfo">
<Setter Property="Grid.Row" Value="{Binding RowIndex}"/>
<Setter Property="Grid.Column" Value="{Binding ColumnIndex}"/>
</Style>
</ItemsControl.ItemContainerStyle>
</ItemsControl>
Screenshot:
when all columns and rows have to be of equal size and elements are consequtive, it is probably simpler to use UniformGrid. Rows and Columns properties support binding.
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<UniformGrid Name="MainGrid" Rows="4" Columns="4"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
here is a nice example of Grid ItemsPanel here: WPF Grid as ItemsPanel for a list dynamically bound to an ItemsControl

I would like to have ListViewItem with data from binding and with 2 events.
My code:
<ListView.ItemTemplate>
<DataTemplate>
<Grid Name="MailListViewItem">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<TextBlock Grid.Column="0" Grid.Row="0" FontWeight="Bold" Text="{Binding Topic}"/>
<TextBlock Grid.Column="1" Grid.Row="0" FontSize="8" Foreground="Blue" Text="{Binding Time}"/>
<TextBlock Grid.Column="0" Grid.Row="1" Grid.ColumnSpan="2" Foreground="Gray" Text="{Binding Text}"/>
</Grid>
</DataTemplate>
Where should I put MouseDoubleClick="Mail_DoubleClick" MouseLeftButtonUp="Mail_MouseLeftButtonUp"?
You could define an ItemContainerStyle with EventSetters:
<ListView>
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<EventSetter Event="MouseLeftButtonUp" Handler="Mail_DoubleClick" />
<EventSetter Event="MouseDoubleClick" Handler="Mail_MouseLeftButtonUp" />
</Style>
</ListView.ItemContainerStyle>
...
Or you could handle the events of the Grid in the DataTemplate provided that you set its Background property to some brush:
<Grid Name="MailListViewItem" Background="Transparent" MouseLeftButtonDown="...">
If you handle MouseLeftButtonDown, there is a ClickCount property of the MouseButtonEventArgs that you can check to determine whether the element as double clicked:
private void MailListViewItem_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
if (e.ClickCount == 2)
{
//doule click
}
else
{
//click...
}
}

So I'm trying to add thickness = 1, outline for grid borders, rows and columns
So I tried following thread
How do i put a border on my grid in WPF?
So to add a border I added following thing, and its working fine
<Border BorderBrush="Black" BorderThickness="2">
<Grid>
<!-- Grid contents here -->
</Grid>
</Border>
But since I have need to add thickness = 1, outline for all above multiple columns and rows also, I tried something like this
</Grid.ColumnDefinitions>
<Border Grid.Row="0" Grid.Column="0" BorderThickness="1" BorderBrush="Black"/>
<Border Grid.Row="0" Grid.Column="1" BorderThickness="1" BorderBrush="Black"/>
which is identifying each column and row and add thickness to them, but this seems quite time consuming and confusing work.
Is there any other proper and quick way to add BorderThickness="1" BorderBrush="Black" to all above Columns and Rows in the grids ?
In the default WPF Grid, you can set ShowGridLines="True". However these lines are meant to be designer lines, and not meant for end use.
The common solution I use is a custom GridControl which adds DependencyProperties for GridLines settings, and overrides OnRender to draw them.
public class GridControl : Grid
{
#region Properties
public bool ShowCustomGridLines
{
get { return (bool)GetValue(ShowCustomGridLinesProperty); }
set { SetValue(ShowCustomGridLinesProperty, value); }
}
public static readonly DependencyProperty ShowCustomGridLinesProperty =
DependencyProperty.Register("ShowCustomGridLines", typeof(bool), typeof(GridControl), new UIPropertyMetadata(false));
public Brush GridLineBrush
{
get { return (Brush)GetValue(GridLineBrushProperty); }
set { SetValue(GridLineBrushProperty, value); }
}
public static readonly DependencyProperty GridLineBrushProperty =
DependencyProperty.Register("GridLineBrush", typeof(Brush), typeof(GridControl), new UIPropertyMetadata(Brushes.Black));
public double GridLineThickness
{
get { return (double)GetValue(GridLineThicknessProperty); }
set { SetValue(GridLineThicknessProperty, value); }
}
public static readonly DependencyProperty GridLineThicknessProperty =
DependencyProperty.Register("GridLineThickness", typeof(double), typeof(GridControl), new UIPropertyMetadata(1.0));
#endregion
protected override void OnRender(DrawingContext dc)
{
if (ShowCustomGridLines)
{
foreach (var rowDefinition in RowDefinitions)
{
dc.DrawLine(new Pen(GridLineBrush, GridLineThickness), new Point(0, rowDefinition.Offset), new Point(ActualWidth, rowDefinition.Offset));
}
foreach (var columnDefinition in ColumnDefinitions)
{
dc.DrawLine(new Pen(GridLineBrush, GridLineThickness), new Point(columnDefinition.Offset, 0), new Point(columnDefinition.Offset, ActualHeight));
}
dc.DrawRectangle(Brushes.Transparent, new Pen(GridLineBrush, GridLineThickness), new Rect(0, 0, ActualWidth, ActualHeight));
}
base.OnRender(dc);
}
static GridControl()
{
DefaultStyleKeyProperty.OverrideMetadata(typeof(GridControl), new FrameworkPropertyMetadata(typeof(GridControl)));
}
}
It can be used like this :
<local:GridEx ShowCustomGridLines="True"
GridLineBrush="#FF38B800"
GridLineThickness="2">
...
</local:GridEx>
In my WPF Application I have a two textblocks which get filled from the code behind with a run. Every second line should have a different background color so it gets easier to read. Unfortunately, the lines are only dyed as far as they are written. But I want the background color to go over the entire line and not just the written area.
Code:
for (int i = 0; i < GlobalSettings.prefixList.Count; i++)
{
runLeft = new Run(GlobalSettings.prefixList[i].prefix + "\n");
runRight = new Run(GlobalSettings.prefixList[i].amount + "\n");
if (i % 2 == 0)
{
runLeft.Background = Brushes.Gray;
runRight.Background = Brushes.Gray;
}
else
{
runLeft.Background = Brushes.LightGray;
runRight.Background = Brushes.LightGray;
}
tblock_StatisticsLeft.Inlines.Add(runLeft);
tblock_StatisticsRight.Inlines.Add(runRight);
}
Example Picture
The two textblocks are seamlessly together in the middle so it would look like it is a single line in a single textblock. The spaces between the lines are negligible if this makes it easier.
Is there a solution without using a textbox or richtextbox?

I left out all the other stuff of the control that is not relevant.
You could (should) use an ItemsControl. Set the ItemsSource property of it to your GlobalSettings.prefixList collection, i.e. you replace your for loop with this:
ic.ItemsSource = GlobalSettings.prefixList;
Make sure that "prefix" and "amount" are public properties (and not fields) of your "prefix" type or whatever you call it:
public string prefix { get; set; }
You then put the Grid with the TextBlocks in the ItemTemplate of the ItemsControl and bind the TextBlocks to the "prefix" and "amount" properties:
<ScrollViewer Grid.Row="2" Grid.RowSpan="3" Grid.Column="1" Grid.ColumnSpan="2" Margin="10,35,12,12" Name="sv_PrefixList">
<ItemsControl x:Name="ic" AlternationCount="2">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid x:Name="grid">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1*"/>
<ColumnDefinition Width="1*"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" x:Name="tblock_StatisticsLeft" HorizontalAlignment="Stretch" LineHeight="20" TextWrapping="Wrap" Margin="0,0,0,0" VerticalAlignment="Stretch" TextAlignment="Left"
Text="{Binding prefix}"/>
<TextBlock Grid.Column="1" x:Name="tblock_StatisticsRight" HorizontalAlignment="Stretch" LineHeight="20" TextWrapping="Wrap" Margin="0,0,10,0" VerticalAlignment="Stretch" TextAlignment="Right"
Text="{Binding amount}"/>
</Grid>
<DataTemplate.Triggers>
<Trigger Property="ItemsControl.AlternationIndex" Value="0">
<Setter Property="Background" Value="Gray" TargetName="grid"/>
</Trigger>
<Trigger Property="ItemsControl.AlternationIndex" Value="1">
<Setter Property="Background" Value="LightGray" TargetName="grid"/>
</Trigger>
</DataTemplate.Triggers>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</ScrollViewer>
This should get you coloured lines.
Here is the correct way of doing this:
Xaml:
<Window.Resources>
<local:BackConverter x:Key="BackConverter"/>
</Window.Resources>
<Grid Margin="10">
<ItemsControl Name="ic">
<ItemsControl.ItemTemplate>
<DataTemplate>
<DockPanel LastChildFill="False">
<DockPanel.Background>
<MultiBinding Converter="{StaticResource BackConverter}">
<Binding />
<Binding RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType=ItemsControl}"/>
</MultiBinding>
</DockPanel.Background>
<TextBlock DockPanel.Dock="Left" Text="{Binding Left}">
</TextBlock>
<TextBlock DockPanel.Dock="Right" Text="{Binding Right}">
</TextBlock>
</DockPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
c# code:
public class obj
{
public string Left { get; set; }
public string Right { get; set; }
}
public MainWindow()
{
InitializeComponent();
DataContext = this;
List<obj> objects = new List<obj>();
for (int i = 0; i < 10; i++)
{
var left = "aaaaa";
var right = "bbbbb";
objects.Add(new obj() { Left = left, Right = right });
}
ic.ItemsSource = objects;
}
the converter:
public class BackConverter : IMultiValueConverter
{
public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
var index = ((ItemsControl)values[1]).Items.IndexOf(values[0]);
if (index % 2 == 0)
return Brushes.Gray;
return Brushes.White;
}
public object[] ConvertBack(object value, Type[] targetTypes, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotImplementedException();
}
}
xmal code:
<ListBox x:Name="listbox2" Margin="0,0" SelectionChanged="listbox2_SelectionChanged" Hold="listbox2_Hold" >
<ListBox.ItemContainerStyle >
<Style TargetType="ListBoxItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch"></Setter>

</Grid>
</Border>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
class list which is bind to list box is
List < contactsclass > contacts = new List < contactsclass >();
PHONE and NAME are getter setter of the contactclass's variables
how can i get this variable's value on hold event of listbox .. i am trying following code
private void listbox2_Hold(object sender, System.Windows.Input.GestureEventArgs e)
{
//contextmenucontact = (contactsclass)(sender as ListBox).DataContext;
contextmenucontact = (contactsclass)listbox2.SelectedItem;
MessageBox.Show(contextmenucontact.name);
}
if is just the selected item is just use the ToString Function, see this:
if (listBox1.SelectedItem != null)
{
string itemText = listBox1.SelectedItem.ToString();
contextmenucontact = new contactsclass();
contextmenucontact.name = itemText;
MessageBox.Show(contextmenucontact.name);
}

foreach (SourceFile sf in manager.getBrainClasses())
{
sf.getVisualizer().Fill = Brushes.Red;
Canvas.SetZIndex(sf.getVisualizer(), 0);
}
this.getVisualizer().Fill = Brushes.Blue;
Canvas.SetZIndex(this.getVisualizer(), 1);
manager.window.RootLayer.InvalidateArrange();
manager.window.RootLayer.InvalidateVisual();
}
The Ellipse is referenced by this.getVisualizer();
However, nothing changes? How can I bring one Ellipse to the front?
It's not fully clear from your code post how the ellipses are added to the canvas but here is a small sample that does essentially what you want to do:
<Grid>
<Canvas x:Name="RootLayer" Width="500" Height="500" />
</Grid>
And in the constructor of the code behind, create some ellipses:
for (int i = 0; i < 10; i++)
{
Ellipse e = new Ellipse
{
Width = 100,
Height = 100,
Fill = new SolidColorBrush(
Color.FromArgb(0xDD,
(Byte) r.Next(255)
(Byte) r.Next(255)
(Byte) r.Next(255))),
Stroke = Brushes.Black,
StrokeThickness = 1,
};
e.MouseUp += new MouseButtonEventHandler(e_MouseUp);
Canvas.SetLeft(e, r.Next(400));
Canvas.SetTop(e, r.Next(400));
RootLayer.Children.Add(e);
}
Event handler to handle mouse click on the ellipses
void e_MouseUp(object sender, MouseButtonEventArgs e)
{
foreach (UIElement item in RootLayer.Children)
Panel.SetZIndex(item, 0);
Panel.SetZIndex((UIElement)sender, 1);
}
With the code above, whenever an ellipse is clicked (mouse up), it will raise above all the other ellipses in that canvas.
