Is there a event handler for right click event on the tree node?

[Onkar]

I have a RadTreeView on the click the nodes get selected and then at the right click a context menu is shown. This is working fine but the problem is to a context menu for a node I have to first select it and then right click on it. Is there a way by which directly on the right click the node will be selected and the context menu will appear for it.

Hi,

You can handle OnClientContextMenuShowing:

<script type="text/javascript">
       function OnClientContextMenuShowing(sender, args) {
           alert(1);
       }
   </script>
   <telerik:RadTreeView ID="RadTreeView1" runat="server" OnClientContextMenuShowing="OnClientContextMenuShowing">
       <Nodes>
           <telerik:RadTreeNode runat="server" Text="Root RadTreeNode1">
               <Nodes>
                   <telerik:RadTreeNode runat="server" Text="Child RadTreeNode 1">
                   </telerik:RadTreeNode>
                   <telerik:RadTreeNode runat="server" Text="Child RadTreeNode 2">
                   </telerik:RadTreeNode>
               </Nodes>
           </telerik:RadTreeNode>
           <telerik:RadTreeNode runat="server" Text="Root RadTreeNode2">
           </telerik:RadTreeNode>
       </Nodes>
   </telerik:RadTreeView>

Hi Peter,

Thanks for your reply. I tried using the  OnClientContextMenuShowing but the problem is I need to make a call to a server side function. I have a function which handles the OnNodeClick event I need to call the same function when the right click is done. I tried using the client side method and from there trying to invoke the server side method but that was not possible. Could you suggest me a way how that can be accomplished.

Hi Onkar,

Please, try the following:

<script type="text/javascript">

       function OnClientContextMenuShowing(sender, args) {
           args.get_node().select();
           $telerik.cancelRawEvent(args.get_domEvent());
       }

   </script>
   <telerik:RadTreeView ID="RadTreeView1" runat="server" OnClientContextMenuShowing="OnClientContextMenuShowing"
       OnNodeClick="RadTreeView1_NodeClick">
       <Nodes>
           <telerik:RadTreeNode runat="server" Text="Root RadTreeNode1">
               <Nodes>
                   <telerik:RadTreeNode runat="server" Text="Child RadTreeNode 1">
                   </telerik:RadTreeNode>
                   <telerik:RadTreeNode runat="server" Text="Child RadTreeNode 2">
                   </telerik:RadTreeNode>
               </Nodes>
           </telerik:RadTreeNode>
           <telerik:RadTreeNode runat="server" Text="Root RadTreeNode2">
           </telerik:RadTreeNode>
       </Nodes>
   </telerik:RadTreeView>

protected void RadTreeView1_NodeClick(object sender, RadTreeNodeEventArgs e)
   {
       Response.Write(e.Node.Text);
   }

Kind regards,
