Hello,

In a RadTreeview I want to display an optional Textbox in each item.
I used a HierarchicalDataTemplate attached to the RadTreeview.
Now the width of the TextBox is equal to the width of the (header)text shown in the TextBlock.
I want to stretch the width of the TextBox to fill up the width of the whole item in the Treeview.
HorizontalAlignment= "Stretch" in the HierarchicalDataTemplate does not work.
Has anyone an idea to fix this?

<telerik:HierarchicalDataTemplate x:Key="ItemTemplate" ItemsSource="{Binding Converter={StaticResource HierarchyConverter}}"

telerik:ContainerBinding.ContainerBindings="{StaticResource BindingsCollection}">

<Grid x:Name="HeaderRow" Width="Auto" HorizontalAlignment="Stretch">

<Grid.RowDefinitions>

<RowDefinition Height="Auto" />

<RowDefinition Height="*"/>

</Grid.RowDefinitions>

<TextBox Text="{Binding OmsText, Mode=TwoWay}" Visibility="{Binding OmsVisiblity, Mode=TwoWay}" HorizontalAlignment="Stretch" Height="Auto" TextWrapping ="Wrap" Grid.Row="1" />

<TextBlock Text="{Binding Text, Mode=TwoWay}" HorizontalAlignment="Stretch"/>

</Grid>

</telerik:HierarchicalDataTemplate>

Hello Henk,

You need to set HorizontalContentAlignment to Stretch of each RadTreeViewItem. To do that, you can set an ItemContainerStyle of RadTreeView:

<telerik:RadTreeView>

<telerik:RadTreeView.ItemContainerStyle>

<Style TargetType="telerik:RadTreeViewItem">

<Setter Property="HorizontalContentAlignment" Value="Stretch" />

</Style>

</telerik:RadTreeView.ItemContainerStyle>

</telerik:RadTreeView>

Let me know if it helps.
