    I am having the hardest time trying to get the value of a rad treenode when i'm using the radcontextmenu.  When I right click the item, I'm using the OnClientContextMenuShowing event to be able to capture this information in javascript.  How can I get the value of the treenode that the context menu is associated with.  Also, if I view source on the page with the rad treeview, I can't see the value stored anywhere in the html like I would if I set the value of a ASP.Net treeview control.  Any help would be appreciated as this should be a relatively easy and common scenario.  I don't want to use server side options just to be clear.  Thanks in advance for your help.

    Hello Michael,

    Try the following approach in order to get RadTreeNode client object in OnClientContextMenuShowing event handler.

    ASPX:
     
    <telerik:RadTreeView ID="RadTreeView1" runat="server" OnClientContextMenuShowing="OnClientContextMenuShowing">  
        <ContextMenus> 
            <telerik:RadTreeViewContextMenu ID="ContextMenu">  
                <Items> 
                    <telerik:RadMenuItem Text="Copy" Value="Copy">  
                    </telerik:RadMenuItem> 
                    <telerik:RadMenuItem Text="Edit" Value="Edit">  
                    </telerik:RadMenuItem> 
                </Items> 
            </telerik:RadTreeViewContextMenu> 
        </ContextMenus> 
        <Nodes> 
            <telerik:RadTreeNode runat="server" Text="Root RadTreeNode1" Value="Value1">  
            </telerik:RadTreeNode> 
             . . .  
        </Nodes> 
    </telerik:RadTreeView> 

    JavaScript:
     
    <script type="text/javascript">  
    function OnClientContextMenuShowing(sender, args)  
    {  
        alert("Clicked node text : "+ args.get_node().get_text()); // Get the node text  
        alert("Clicked node value : "+args.get_node().get_value()); // Get the node value  
    }  
    </script> 

    Thanks,
    Princy.
