How to stretch item horizontally

[Henk]

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.

Kind regards,

Hi,
I make value to "Left", but items not align to left side of the tree. Items are still keep small (considerable) space in left side of the tree.

Hi Saw,

Since this is a very old thread, is it possible for you to open a new support ticket with more details about your specific scenario ? We are not exactly sure what you wish to achieve. Thank you in advance for your cooperation.
