Unable to set the tree view node properties on server side click event

[Pena]

Hi,

I have  a treeview with parent node and child nodes. When clicked on any node, I need to have that node of the treeview expanded and clicked node to be disabled. The code below did not work.. I have tried setting a forecolor property to distinguish clicked node but that did not work either. Thanks for your help.  

 

Public Sub RadTreeView1_NodeClick1(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadTreeNodeEventArgs) Handles RadTreeView1.NodeClick
        e.Node.Expanded = True
        e.Node.Enabled = False
        'e.Node.ForeColor = Drawing.Color.Aqua
        If (e.Node.Value > 9000) Then
            Session("Page1ToNavigate") = e.Node.Text
            Response.Redirect("~/Page1.aspx")

        Else

            Session("Page2ToNavigate") = e.Node.Value
            Response.Redirect("~/Page2.aspx")

        End If
    End Sub

Hello Pena,

You may try to add the NodeClick event inline like in this sample project that worked at my side.

Hope this will be helpful.
