Hi,
I'm using a RadTreeView:

<telerik:RadTreeView ID="RadTreeView1" runat="server" DataFieldID="CompetitionID" 
            DataTextField="Description"  
            DataValueField="CompetitionID"  
            CheckChildNodes="True"
</telerik:RadTreeView> 

I filled in all the root nodes
When I try to expand a node in order to populate that node "on demand", I want to have to node in order to find out its id and its position in the tree:

Protected Sub RadTreeView1_NodeExpand1(ByVal sender As ObjectByVal e As Telerik.Web.UI.RadTreeNodeEventArgs) Handles RadTreeView1.NodeExpand 
        PopulateNodeOnDemand(e, TreeNodeExpandMode.ServerSideCallBack) 
End Sub 
 


I see that the RadTreeNodeEventArgs "e" is empty. No nodes in.


Can someone tell me what's the problem?
Thanks in advance

Hello Matteo Pellizzoni,

From first look the code seems OK but I can not see where you set the ExpandMode of the RadTreeNodes and what is it.

Could you please attach the full code so we can be able to help you.

Thank you!

All the best,
