Hi!

I have an error with the TreeView control.  If you build the tree and give a name to each item, then for some reason you want to rebuild the tree, you clear the nodes. You rebuild the tree (for a refresh).  Then you get many error, and Silverlight can become all white.  It seems there is an error when you clear a tree with node and you reuse the same name for another node.

I have example put this code in a button to refresh the treeview called T: If you refresh the tree and you try to expand the node you get errors.

        T.Nodes.Clear()

        Dim Node1 As New Liquid.Node

        Dim Node2 As New Liquid.Node

        Dim Node11 As New Liquid.Node

        T.Nodes.Add(Node1)

        T.Nodes.Add(Node2)

        Node1.Nodes.Add(Node11)

        Node1.Name = "A"

        Node2.Name = "B"

        Node11.Name = "AA"

        Node1.Title = "A"

        Node2.Title = "B"

        Node11.Title = "AA"

Hi,

Thanks for this post.  I'm unable to reproduce the error you describe, can you provide a sample project showing this error?

A couple of points from looking at your code, instead of T.Nodes.Clear() use T.Clear().  The setting of the Name property in Silverlight has certain restrictions, please see the MSDN about these properties.

Thanks!

OK, using T.Clear() instead of T.Nodes.Clear() fixed the issue in my application.  Thank you!!
