binding to FullPath or Header with LOD

[StrandedPirate]

I've got a tree view on my page that i'm binding to by setting the ItemsSource property. How do I fine tune the binding so that I bind specific properties from my source dataset objects to the FullPath or the Header properties of the RadTreeViewItem node that is eventually created?

telerik:RadTreeView Grid.Column="0" Grid.Row="1" PathSeparator="\" ItemTemplate="{StaticResource DirectReportsTemplate}"

 

 

 

ItemsSource="{Binding ElementName=tbl_PathDomainDataSource, Path=Data}"

 

 

 

SelectedValuePath="PathID" x:Name="FolderTreeView"

 

 

 

IsLoadOnDemandEnabled="True" LoadOnDemand="tbl_PathRadTreeView_LoadOnDemand"

 

 

 

IsLineEnabled="False" HorizontalAlignment="Stretch"

 

 

 

IsEditable="True" ExpanderStyle="{StaticResource ExpanderStyle}" Selected="FolderTreeView_Selected">

I think I found how to do this but its not working for the FullPath property. This does work for the Tag property. Why would this work for some properties and not others. Is there a list of properties on your site that this will work with?

Hello Joey,

FullPath property is a read-only property and is not a DependencyProperty. In order to use a property in a Binding Expression it should be a DependencyProperty and should not be read-only. This is the reason that the binding is not working.

Why you need to set the FullPath property? What is your scenario?
