[Solved] Strikethroughed text in a TreeViewItem using a ItemTemplate

[Tobias]

Hi folks,
I have the following problem:

1. I have a RadTreeViewItemTemplate 
2. I want to set the text decoration to strikethrough
3. I want to use a template and not a new control
4. Please help. :)

I checked several blogs and forum posts, nothing really helped me. 

Thanks a lot!

<telerik:RadTreeView.ItemTemplate>

    <telerik:HierarchicalDataTemplate ItemsSource="{Binding Children}">

        <Grid>

            <TextBlock x:Name="MyText" Text="{Binding Name}"/>

        </Grid>

    </telerik:HierarchicalDataTemplate>

</telerik:RadTreeView.ItemTemplate>

UPDATE
I solved the first problem with the following changes:

<Grid>
<TextBlock Text="{Binding Name}"/>
<Rectangle Height="1" VerticalAlignment="Center" Fill="Black" />
</Grid>

So, I need a way how to set diffrent template - because only delete items should be strikeouted.

SOLUTION

Hi,
I found a solution. You need a TreeViewItemTemplateSelector and a HierarchicalDataTemplate incl. Code-Behind files.
It works! Yay.
