I have listbox which will show the list of text and its status. How shall i show the text in the left side and Status control on the right most side?
This is how i was trying.
<ListBox.ItemTemplate>
<DataTemplate>
<DockPanel>
<TextBlock DockPanel.Dock="Left" Text="{Binding Path=Name}" Style="{StaticResource TextBlockTitle}"/>
<ContentControl DockPanel.Dock="Right" HorizontalAlignment="Right" Content="{Binding Status}" ContentTemplate="{StaticResource StatusTemplate}" />
</DockPanel>
</DataTemplate>
This code is showing the status control just after the text.
Would use a Grid with two columns:
* sized
Auto sized (or set a SharedSizeGroup if you want synchronization between items)
The first column will take up all space left. For size sharing you will also need to set Grid.IsSharedSizeScope on e.g. the ListBox element.
The items also need to be stretched.

If I put the Column where the toolbar is hosted to be very big (800) then all the text is visible:
but if I put a smaller column this happens:
But I cannot understand why:
<DataTemplate x:Key="IconFilterButton">
<StackPanel Orientation="Horizontal">
<TextBlock
VerticalAlignment="Center"
Style="{StaticResource LargeIconStyle}"
Text="{Binding}" />
<TextBlock
Margin="6,0,0,0"
VerticalAlignment="Center"
DataContext="{Binding}"
Style="{StaticResource BodyTextStyle}"
Text="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=ToggleButton}, Path=Tag}" />
</StackPanel>
</DataTemplate>
and here the definition
<ToggleButton
x:Name="DFilter"
Click="Filtering_Click"
Content=""
ContentTemplate="{StaticResource IconFilterButton}"
Tag="1d"
/>
<ToggleButton
x:Name="WFilter"
Click="Filtering_Click"
Content=""
ContentTemplate="{StaticResource IconFilterButton}"
Tag="1w"
/>
Even worst if I click on the button once they are out:
and then the text is visible but is wrong as the TextBlock is not considered in the object size:
The WPF ToolBar control uses a custom panel for the overflow Popup. In many styles, the ToolBarOverFlowPanel has a property WrapWidth set to a static value like 200. This determines how many items can be displayed before it wraps to another row in the popup.
I've created custom styling for this control and have found that the ToolBarOverFlowPanel used internally is buggy. That's probably the source of your problem.
You can re-template the ToolBar and wire-up a different value for WrapWidth to try to fix the issue, but my guess is that you'll still run into layout problems.
Otherwise, you might consider making your own replacement control.
Very new to WPF.
<TreeView Grid.Column="0" x:Name="DataTree" MinWidth="175" BorderThickness="0">
<TreeView.Resources>
<HierarchicalDataTemplate DataType="{x:Type self:DispatchTreeTerritoryItem}" ItemsSource="{Binding ClientLocations}">
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Name}" />
</StackPanel>
</HierarchicalDataTemplate>
<DataTemplate DataType="{x:Type self:DispatchTreeClientLocationItem}">
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding ClientName,StringFormat='({0}) '}" />
<TextBlock Text="{Binding Address}" />
</StackPanel>
</DataTemplate>
</TreeView.Resources>
</TreeView>
The data in the DispatchTreeClientlocationItem properties (ClientName and Address), do not fit within the width of the treeview. So when the items are created the treeview control expands itsself horizontally to allow all the tree node's text to be visible.
This is not desired behavior. I would like it to behave like WinForms TreeView, where the text is just truncated at the edge of the control. Is that possible in WPF? And how?
UPDATE
Following #Funk's comment and the suggestion in the linked question my TreeView XAML now looks like:
<TreeView x:Name="DataTree" Grid.Column="0" MinWidth="175" BorderThickness="0"
ScrollViewer.HorizontalScrollBarVisibility="Disabled">
I've observed no change in the behavior. When node text is too long to fit within the horizontal confines of the TreeView, the TreeView expands horizontally to display all the text.
Here's a couple screenshots to illustrate the problem. When expanding a territory node, the child node's contents cause the TreeView to expand horizontally.
if TreeView is located in a Grid and ColumnDefinition has Width="Auto", expanding is an expected behavior.
Try set MaxWidth (on ColumnDefinition or on TreeView), or proportional width * / fixed width (on ColumnDefinition)
Grid rows (RowDefinition) have similar behavior when their Height is set to Auto
I am using a grid with single row. I have placed a single LongListSelector within that row. The ItemTemplate is as follows,
<Grid x:Name="LayoutRoot" Background="Transparent">
<Grid.RowDefinitions>
<RowDefinition/>
</Grid.RowDefinitions>
<!--when we dont mention any of the height and width properties then control tries to first occupy the minimum height/width required and then it streches to the extent it is possible-->
<phone:LongListSelector Grid.Row="0" x:Name="CLASS1">
<phone:LongListSelector.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Margin="25,20" Background="#FF616464" Width="Auto">
<TextBlock Text="{Binding title, Mode=TwoWay}" FontSize="40" Margin="20,20" Foreground="White" TextAlignment="Left" TextWrapping="Wrap" FontStyle="Normal" FontFamily="Segoe UI"/>
</StackPanel>
</DataTemplate>
</phone:LongListSelector.ItemTemplate>
</phone:LongListSelector>
</Grid>
Now I know that if we don't mention the width,MaxWidth values in the XAML file or in the properties, the Textblock above will stretch itself to the width it really needs to fit in the text. If there still some more width remaining it will expand till that extent. However I want to wrap the text of the Textblock. At the same time I want to utilize all the width available for stretching the TextBlock. So basically I want that the Textblock to stretch itself using the maximum width available and if the Text within it is still longer then I want to wrap it. Is there any solution to achieve this. I can use text wrap by setting constant value for width. As I want to deploy this application on different models then can I make it generic? Is there anyway to use parent's width?
All you have to do is to replace StackPanel with Grid.
<DataTemplate>
<Grid Margin="25,20" Background="#FF616464" Width="Auto">
<TextBlock Text="{Binding title, Mode=TwoWay}" FontSize="40" Margin="20,20" Foreground="White" TextAlignment="Left" TextWrapping="Wrap" FontStyle="Normal" FontFamily="Segoe UI"/>
</Grid>
</DataTemplate>
Result:
try this property
HorizontalContentAlignment="Stretch"
<DataTemplate x:Key="dirtSimple">
<TextBlock Margin="10,0,0,0" Text="{Binding Path=CurrentBook.Published, StringFormat=d}"></TextBlock>
</DataTemplate>
<ControlTemplate x:Key="lbWrapPanelTemplate">
<StackPanel Orientation="Horizontal" Margin="2" Background="Aqua">
<ItemsPresenter></ItemsPresenter>
</StackPanel>
</ControlTemplate>
...
<ListBox Template="{StaticResource lbWrapPanelTemplate}" x:Name="bookListBox" Grid.Row="0" ItemsSource="{Binding Path=BookSource}" ItemTemplate="{StaticResource dirtSimple}" >
</ListBox>
The list box is displaying correctly, with a beautiful "Aqua" background, and each item is boringly displayed with just a date. For some reason though the items are not flowing horizontally. I originally tried it with the Silverlight Toolkit's WrapPanel, with the same problem, but I can't even get it to work with a built-in StackPanel, so I suspect I'm missing something.
Are you trying to get selection-based behavior that a ListBox provides? If not, use an ItemsControl (and supply an ItemsPanel as below).
The reason it's not going horizontal is the ItemsPresenter ultimately has its own panel it lays out items in. It's not inserting each item separately into your StackPanel (or WrapPanel), it's putting them in its own panel
What you want to do is specify a value for ItemsPanel like so:
<ListBox ItemTemplate="{StaticResource dirtSimple}">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
</ListBox>
I have a WPF listbox which displays messages. It contains an avatar on the left side and the username and message stacked vertically to the right of the avatar. The layout is fine until the message text should word wrap, but instead I get a horizontal scroll bar on the listbox.
I've Googled and found solutions to similar issues, but none of them worked.
<ListBox HorizontalContentAlignment="Stretch" ItemsSource="{Binding Path=FriendsTimeline}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Border BorderBrush="DarkBlue" BorderThickness="3" CornerRadius="2" Margin="3" >
<Image Height="32" Width="32" Source="{Binding Path=User.ProfileImageUrl}"/>
</Border>
<StackPanel Orientation="Vertical">
<TextBlock Text="{Binding Path=User.UserName}"/>
<TextBlock Text="{Binding Path=Text}" TextWrapping="WrapWithOverflow"/> <!-- This is the textblock I'm having issues with. -->
</StackPanel>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Contents of the TextBlock can be wrapped using property TextWrapping.
Instead of StackPanel, use DockPanel/Grid.
One more thing - set ScrollViewer.HorizontalScrollBarVisibility property to Disabled value for the ListBox.
Updated Hidden to Disabled based on comment from Matt. Thanks Matt.
The problem might not be located in the ListBox. The TextBlock won't wrap, if one of the parent controls provides enough space, so that it hasn't the need to wrap. This might be caused by a ScrollViewer control.
If you want to prevent TextBlock to grow, and you want it to just fit in the size of the listbox, you should set the width of it explicitly.
In order to change it dynamically, it means not a fix value, but you need to bind it to its proper parent element in the visual tree. You can have something like this:
<ListBox ItemsSource="{Binding MyItems}" Name="MyListBox">
<ListBox.Resources>
<Style TargetType="ListBoxItem">
<Setter Property="Width"
Value="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=ScrollContentPresenter}, Path=ActualWidth}" />
</Style>
</ListBox.Resources>
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Title}" TextWrapping="Wrap" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
If it does not work, try to find the proper elements (which has to be binded to what) with the Live Visual Tree in Visual Studio.
