    Hi Tejas,

    Even though RadTreeList does not currently expose its own context menu, you can easily bind a RadContextMenu to RadTreeList. You can refer to a similar demo using RadListView and RadContextMenu. The approach is the same - you use the javascript oncontextmenu event of the tree list items to show a context menu. To attach an client oncontextmenu event handler to the tree list items, you can use the ItemCreated event of the control:

    protected void RadTreeList1_ItemCreated(object sender, TreeListItemCreatedEventArgs e)
        if (e.Item is TreeListDataItem)
            TreeListDataItem dataItem = (TreeListDataItem)e.Item;
            dataItem.Attributes["oncontextmenu"] = "ShowContextMenu(" + dataItem.DisplayIndex + ");";
