I have a listbox that uses datatemplates and one of the elements in the template is a textblock. Problem is that the words won't wrap, and I don't want to set a fixed size. Anybody that knows how to resolve this problem? It's driving me crazy!
<ListBox Grid.Row=" 1" HorizontalContentAlignment="Stretch" Background="#24221f" ItemsSource="{Binding Messages}" ScrollViewer.VerticalScrollBarVisibility="Visible" ClipToBounds="False" BorderBrush="{x:Null}">
<ListBox.ItemTemplate>
<DataTemplate >
<Border BorderBrush="#24221f" BorderThickness="3" Width=" auto">
<DockPanel Background="{StaticResource blackBackground}" HorizontalAlignment="Stretch" Width="auto">
<Border BorderThickness="3" BorderBrush="Transparent">
<Image Source="{Binding IconImageUrl}" VerticalAlignment="top" Height="22" Width ="22" DockPanel.Dock="Left" />
</Border>
<Border BorderThickness="3" BorderBrush="LightGray" Height="auto" Width="auto" HorizontalAlignment="Left" VerticalAlignment="Center" DockPanel.Dock="Left">
<Image Source="{Binding ProfileImageUrl}" VerticalAlignment="Top" HorizontalAlignment="Left" Height="48" Width ="48" />
</Border>
<StackPanel Orientation="Vertical" DockPanel.Dock="Left" Margin="5,0,0,0">
<Label Content="{Binding Path=Sender}" Foreground="#feb41c" FontFamily="Verdana" FontWeight="Bold" FontSize="14" />
<TextBlock Width="100" Text="{Binding Path=ShortMessage}" Margin="10,0,0,0" Foreground="BlanchedAlmond" TextWrapping="Wrap" FontFamily="Verdana" />
<Label Content="{Binding Path=Time}" Margin="10,0,0,0" Foreground="DarkGray" FontFamily="Verdana" FontStyle="Italic"/>
</StackPanel>
</DockPanel>
</Border>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
StackPanel is Evil :=) when i have strange behaviours in a xaml which include StackPanel, switching to a Grid with right parameters ( fixed sized, or stars or "Auto" ) often fix the issue.
Note also that there is an error in your xaml since you set the DockPanel.Dock of your first image (IconImageUrl) whereas it is in the border that surrrounds it that you should be setting it. That may get the Layout to do strange things.
just try with HorizontalContentAlignment property to "Stretch" of ListBoxItems using the Style
<Style TargetType="{x:Type ListBoxItem}" >
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
</Style>
and also disable the HorizontalScrollBar visibility
ScrollViewer.HorizontalScrollBarVisibility="Disabled"
Update
<Window.Resources>
<SolidColorBrush x:Key="blackBackground" Color="Black"/>
<Style TargetType="{x:Type ListBoxItem}" >
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
</Style>
</Window.Resources>
<Grid>
<ListBox Grid.Row=" 1" HorizontalContentAlignment="Stretch" Background="#24221f" ScrollViewer.HorizontalScrollBarVisibility="Disabled"
ItemsSource="{Binding Messages}" ScrollViewer.VerticalScrollBarVisibility="Visible" ClipToBounds="False" BorderBrush="{x:Null}">

I think this thread answer's your question, see the accespted answer by "Nash" - Force TextBlock to wrap in WPF ListBox
( and remember to upvote the answer the the linked thread if it helps you :) )

I'm using OxyPlot for WPF and the PlotView adds a space to the right of it instead of filling up the entire area as you can see in this picture:
I added the black box to show to where the PlotView should extend to.
But in the designer the PlotView does extrend so far:
Is this something that is fixable? Or is the only way to fix it is to "cheat" and instead of fitting controls together in a panel i just overlap the rightside over the PlotView.

I guess you bind your PlotView to a PlotModel? In that case you can set the PlotModel's PlotMargins property to set the margins of the plot area within the plot view and assign values for all four sides independently.
In order to get completely rid of the margin at the right side, you need to assign a negative value.
I have created the plot below using this line
plotModel.PlotMargins = new OxyThickness(40, -8, -8, 35);
I have changed the general background color of the plot view to make it clearer.
Here is my Code:
<Grid>
<ScrollViewer Grid.Row="0" Grid.Column="1" HorizontalScrollBarVisibility="Disabled">
<StackPanel Orientation="Vertical">
<StackPanel Orientation="Horizontal" HorizontalAlignment="Left">
<TextBox MinWidth="80" Name="tbTodoName" Margin="5, 2"/>
<Button Content="Add" Height="30" Margin="5, 0"/>
</StackPanel>
<ListBox Name="lstTodo" ItemsSource="{Binding}" BorderThickness="0" Padding="0" ItemTemplate="{StaticResource TodoTemplate}" ScrollViewer.HorizontalScrollBarVisibility="Disabled" HorizontalAlignment="Stretch">
</ListBox>
</StackPanel>
</ScrollViewer>
</Grid>
and here is a picture of what the program looks like:
As can be seen in the picture, a frame is displayed around the ListBox. I don't understand why, since I set BorderThickness and Padding = "0".
Can someone help me?
You have set a custom ItemTemplate, which is applied only to the items.
You will need to apply the Template as well:
<Grid>
<ScrollViewer Grid.Row="0" Grid.Column="1" HorizontalScrollBarVisibility="Disabled">
<StackPanel Orientation="Vertical">
<StackPanel Orientation="Horizontal" HorizontalAlignment="Left">
<TextBox MinWidth="80" Name="tbTodoName" Margin="5, 2"/>
<Button Content="Add" Height="30" Margin="5, 0"/>
</StackPanel>
<ListBox Name="lstTodo" ItemsSource="{Binding}" BorderThickness="0" Padding="0" ItemTemplate="{StaticResource TodoTemplate}" Template={StaticResource ListBoxNoBorder}
ScrollViewer.HorizontalScrollBarVisibility="Disabled" HorizontalAlignment="Stretch">
</ListBox>
</StackPanel>
</ScrollViewer>
</Grid>
And in your resource dictionary:
<ControlTemplate x:Key="ListBoxNoBorder" TargetType="{x:Type ListBox}">
<Border BorderBrush="Transparent" BorderThickness="0">
<ItemsPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
</Border>
</ControlTemplate>
I got this xaml code:
<UserControl x:Class="CharacterMap.CharacterMapControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

</Border>
<TextBox Text="{Binding FilterString, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Width="125" Height="25" VerticalContentAlignment="Center" />
</StackPanel>
<ScrollViewer x:Name="ScrollViewer" Margin="10,0,10,10" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Grid.Row="1" >

<ItemsControl ItemsSource="{Binding CharDescriptions}" ItemTemplate="{StaticResource ItemsTemplate}" Name="CharItemsControl">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
</Border>
</ScrollViewer>
</Grid>
</UserControl>
It looks something like this:
Before i had the BorderThickness from the button just on 1 but then the borders were overlaying and it looked not so nice.
Now i tried to set the buttons borders thickness to "0,0,1,1" and put a border around the itemscontrol which is "1,1,0,0". The problem is that when i resize the window or in generall the border from the itemscontrol just extends too far and that doesn't look nice either.
How to achieve something like this: ?
You can do something like below. Essentially, you use negative margins to meld all the borders together. On a parent border set a Padding="1" so that the negative margins along the edges can be seen.
The Border around your Button in your DataTemplate would look like this:
<DataTemplate x:Key="ItemsTemplate">
<Border
Margin="-1,-1,0,0"
BorderBrush="Black"
BorderThickness="1">
<Button
Width="26"
Height="23"
HorizontalContentAlignment="Center"
VerticalContentAlignment="Center"
BorderThickness="0"
Content="{Binding TheChar}"
Style="{StaticResource Flat}"
ToolTip="{Binding AggregatedTooltip}"
ToolTipService.BetweenShowDelay="300"
ToolTipService.InitialShowDelay="800"
ToolTipService.IsEnabled="True"
ToolTipService.ShowDuration="10000"
ToolTipService.ShowOnDisabled="True" />
</Border>
</DataTemplate>
The Border around your ItemsControl in your ScrollViewer would have a Padding="1" and look like this:
<ScrollViewer x:Name="ScrollViewer"
Grid.Row="1"
Margin="10,0,10,10"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch">
<Border
Padding="1"
SnapsToDevicePixels="True">
<ItemsControl
Name="CharItemsControl"
ItemTemplate="{StaticResource ItemsTemplate}"
ItemsSource="{Binding CharDescriptions}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
</Border>
</ScrollViewer>
I would like to make the "Cartoon" below to be aligned to the right and the yellow part to fill all the space in the middle of my ListBox item.
However, all I can get is this:
Here is my layout xaml:
<Window x:Class="Cartoons.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:sys="clr-namespace:System;assembly=mscorlib"
Title="Cartoons" Height="350" Width="525" SizeToContent="Width">
<DockPanel x:Name="mainPanel">
<Border Background="Green" DockPanel.Dock="Bottom" Width="Auto" Height="Auto">
<Grid Margin="2" Height="Auto">
<ListBox Name="listBoxCartoons" SelectionChanged="ListBox_SelectionChanged">
<ListBox.ItemTemplate>
<DataTemplate>
<DockPanel HorizontalAlignment="Stretch" Background="PowderBlue">
<DockPanel HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Background="AliceBlue" DockPanel.Dock="Left" >
<Image Source="<IMAGE_LOCATION>" Width="64" Height="64" Stretch="Fill"/>
</DockPanel>
<DockPanel HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Background="AliceBlue" DockPanel.Dock="Right">
<TextBlock Text="Cartoon" VerticalAlignment="Center"/>
</DockPanel>
<DockPanel HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Background="Yellow">
<StackPanel Orientation="Vertical" VerticalAlignment="Center">
<TextBlock Text="Character 1"/>
<TextBlock Text="Walt Disney"/>
<TextBlock Text="Speedy Gonzales"/>
</StackPanel>
</DockPanel>
</DockPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
</Border>
</DockPanel>
</Window>
I have tried many things but regardless what I do, it is alwasy displayed with large white space to the right.
Much appreciated,
If you're not avoiding hard-coding numbers in, such as margins, you could try this (tested in Visual Studio for your convenience):
<Border Background="Green" DockPanel.Dock="Bottom" Width="Auto" Height="Auto">
<Grid Margin="2" Height="Auto">
<ListBox Name="listBoxCartoons" SelectionChanged="ListBox_SelectionChanged">
<ListBoxItem>
<!-- Width of the below element may have to be adjusted -->
<Grid HorizontalAlignment="Stretch" Width="499">
<Image Source="<IMAGE_LOCATION>" Width="64" Height="64" Stretch="Fill" HorizontalAlignment="Left"/>
<!-- Margin of the below element may have to be adjusted -->
<StackPanel Orientation="Vertical" VerticalAlignment="Center" HorizontalAlignment="Stretch" Background="Yellow" Margin="69,8,0,8">
<TextBlock Text="Character 1"/>
<TextBlock Text="Walt Disney"/>
<TextBlock Text="Speedy Gonzales"/>
</StackPanel>
<Label Background="AliceBlue" Content="Cartoon" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" HorizontalAlignment="Right"/>
</Grid>
</ListBoxItem>
</ListBox>
</Grid>
</Border>
Also, there is an extra near the bottom of your XAML, above .
The problem is that the ListBox will generate container elements (of type ListBoxItem) for each item - these will, by default, align content to the left. To change that, add this to your ListBox:
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch"></Setter>
</Style>
</ListBox.ItemContainerStyle>
I figured it out.
Needed to set HorizontalContentAlignment="Stretch" on ListBox.
That resolved the issue. Just modify above line
<ListBox Name="listBoxCartoons" SelectionChanged="ListBox_SelectionChanged">
to
<ListBox Name="listBoxCartoons" HorizontalContentAlignment="Stretch" SelectionChanged="ListBox_SelectionChanged">
and it worked.
I have a simple Silverlight 3 UserControl whose width increases or decreases based on user input.
The controls become more wide or more narrow as desired, except for the ListBox items. The ListBox Items grow horizontally to fit their content regardless of HorizontalContentAlignment being set to 'Stretch'.
Should I be able to set a property on ListBox.ItemContainerStyle to tell it to widen/narrow with the parent ListBox? There needs to be no horizontal scrolling within this Listbox.
Or is there a way to specify the ItemTemplate's StackPanel width that can be modified at runtime? I have bound this to a StaticResource, but do not understand whether I should be able to change the resource value. Can I create and bind to a DependencyProperty of the UserControl itself? I have not determined the syntax of this within the xaml.
