Hello,

I have put EventArgs it points to an error on e.Node that System.EventArgs does not contain definition for Node.

If i replace EventArgs with TreeNodeEventArgs, then that error goes away but I get an error on compilation:

Compiler Error Message: CS0123: No overload for 'TreeView2_SelectedNodeChanged' matches delegate 'System.EventHandler'

<asp:TreeView ID="TreeView2" runat="server" OnUnload="TreeViewMain_Unload"
ontreenodepopulate="TreeView2_TreeNodePopulate"
onselectednodechanged="TreeView2_SelectedNodeChanged">
<Nodes>
<asp:TreeNode PopulateOnDemand="True" Text="Machine Groups"
Value="Machine Groups"></asp:TreeNode>
</Nodes>
</asp:TreeView>
Please help me out.

Hey there,

If you want to get the selected Node of the TreeView inside TreeView2_SelectedNodeChanged, you can do this inside the event:

C#

TreeView objTreeView = (TreeView)sender;
           if (objTreeView != null)
           {
               TreeNode selectedNode = objTreeView.SelectedNode;
               //Do something
           }

and you'll have to use System.EventArgs and this is what the event supports.

Let me know if it helps.

Azee...
