Hi, 
I have an issue regarding the view of tne contextMenu in the RadTreeView. I would like to view the contextMenu only on the parentnode and not on the child node while right_clicking  the mouse.
Thank you for any help

<telerik:RadTreeView ID="rtvCatalog" runat="server" EnableDragAndDrop="True"
                     OnNodeDrop="rtvCatalog_HandleDrop" MultipleSelect="false"
                     EnableDragAndDropBetweenNodes="true"
                     OnClientNodeDropping="onNodeDropping"
                     OnClientMouseOver="onNodeMouseOver"
                     OnClientMouseOut="onNodeMouseOut"
                     AllowNodeEditing="true"
                     OnNodeEdit="rtvCatalog_NodeEdit"
                     CausesValidation="false" Width="100%"
                     OnContextMenuItemClick="onMenuItemClick">
    <ContextMenus>
        <telerik:RadTreeViewContextMenu ID="mnuGroup" runat="server">
            <Items>
                <telerik:RadMenuItem Text="Order ascending" Value="Ascending"
                                 ImageUrl="~/Images/Sort-ascend.png" runat="server">
                </telerik:RadMenuItem>
                <telerik:RadMenuItem Text="Order descending" Value="Descending"
                                 ImageUrl="~/Images/Sort-descend.png" runat="server">
                </telerik:RadMenuItem>
                <telerik:RadMenuItem Text="Copy group in" Value="Select">
                </telerik:RadMenuItem>
            </Items>
        </telerik:RadTreeViewContextMenu>
    </ContextMenus>
</telerik:RadTreeView>

Hi Collince,

Try attaching the following JavaScript code in the OnClientContextMenuShowing client event of the RadTreeView. The ContextMenu will be shown for root level elements only.

JavaScript:
<script type="text/javascript">
    function onClientContextMenuShowing(sender, args) {
        if (args.get_node().get_level() != 0) {
            args.set_cancel(true);
        }
    }
</script>

Thanks,
Shinu.

Hi Colince,

To get the context menu appear only to specific nodes from the RadTreeView control you can use the EnableContextMenu property of the nodes and set it to false for the child nodes.
