Hi Rishi,

Expanding a node should trigger postback only if you set the expand mode of the node to ServerSide.

ASPX:
<telerik:RadTreeView ID="RadTreeView1"   runat="server"  OnNodeCollapse="RadTreeView1_NodeCollapse" OnNodeExpand="RadTreeView1_NodeExpand"
                    <Nodes> 
                        <telerik:RadTreeNode Text="Nodes"  ExpandMode="ServerSide" > 
                       



Thanks
Shinu.

Hi Shinu

But it will Generate a postback.Which i don't want .
 
As the NodeClick Event is get fired without Post back can't it be possible to fire the Expand event without Postback to Server.

Hi Rishi,

One suggestion will be to ajaxify RadTreeView using RadAjaxManager or RadAjaxPanel to prevent the flickering that occurs on clicking the Tree node.
