Removing Nodes - LoadOnDemand

[Paul Gallen]

Hi,

Can you give me and example of removing nodes from your RadTreeView as the code snippet below generates an error, at line 
  

Parent.Items.Remove(DirectCast(e.Source, TreeViewItem))

 Private Sub trvListEvents_Edited(ByVal sender As Object, ByVal e As Telerik.Windows.Controls.RadTreeViewItemEditedEventArgs) Handles trvListEvents.Edited
        If e.OldText <> e.NewText Then
            ActionMenuRequest(DirectCast(e.Source, RadTreeViewItem))
        Else
            Dim Parent As RadTreeViewItem = Me.CurrentTreeViewItem.Parent
            Parent.Items.Remove(DirectCast(e.Source, TreeViewItem))
        End If

    End Sub

Requirements: After Editing a node, if it does not meet a certain criteria, then delete the node.

Note: I am using the RadTreeView with LoadOnDemand

Hello Paul,

Thank you for your feedback. It turned out that you hit a bug in the RadTreeView control. I scheduled it to be fixed for our next release and updated your Telerik points.

For the time being, you can use a workaround which I demonstrated in the attached sample project. Please let me know if this would work for you.

I think you have forgot to attach the sample project.

Thanks

That seems to work fine. I presume you would code the same sort of thing when the user presses the delete key?

Hi Paul Gallen,

Yes, you can use the same approach with the Delete key.
