    Working with RadTreeView file version 6.3.6.0. 

    I'm using server-side LoadOnDemand; It loads the 1st level fine and the server side NodeClick event is firing.
    Expanding a node fires the NodeExpand where I add the next level of data.
        Private Sub AddChildNodes(ByVal node As RadTreeNode) 
            If GetCustomersByNode(CInt(node.Value)) Then 
                Dim row As DataRow 
                For Each row In parentCustomer.Tables(0).Rows 
                    Dim childNode As New RadTreeNode() 
                    childNode.Text = CStr(row("CustomerName")) 
                    childNode.Value = CInt(row("CustomerNum")).ToString() 
                    childNode.ExpandMode = CInt(row("HasChild")) 
                    childNode.PostBack = True 
                    node.Nodes.Add(childNode) 
                Next row 
            End If 
        End Sub 

    When I click on any node level which has been populated via NodeExpand event, it does not perform the server side NodeClick event.
    What can I do to get the server-side event to fire when I click the node?  I've seen a suggestion to use the RadAjaxManager (which I am using for other controls in this page), but I'm not sure how to wire that up.

    Thanks,
    Jim

    Hi Jim ,

    I guess that you're using RadTreeView for ASP.NET.   Please check this help article which explains this issue and how to work-around it.
