  Hello Faisal,
  
  The following code shows how to add RadContextMenu dynamically. Hope this helps you.
  
  aspx:
  

  <telerik:RadTreeView ID="RadTreeView1" runat="server" >

      <Nodes>

         <telerik:RadTreeNode runat="server" Text="Item1">

         </telerik:RadTreeNode>

         <telerik:RadTreeNode runat="server" Text="Item2">

         </telerik:RadTreeNode>

      </Nodes>

  </telerik:RadTreeView>

  
  C#:
  

  protected void Page_Load(object sender, EventArgs e)

     {

         if (!IsPostBack)

         {

             RadTreeViewContextMenu contextMenu1 = new RadTreeViewContextMenu();

             contextMenu1.ID = "ContextMenu1";

             RadMenuItem menuItem1 = new RadMenuItem();

             menuItem1.Text = "item1";

             contextMenu1.Items.Add(menuItem1);

             RadMenuItem menuItem2 = new RadMenuItem();

             menuItem2.Text = "item2";

             contextMenu1.Items.Add(menuItem2);

             RadTreeView1.ContextMenus.Add(contextMenu1);

             RadTreeViewContextMenu contextMenu2 = new RadTreeViewContextMenu();

             contextMenu2.ID = "ContextMenu2";

             RadMenuItem menuItem = new RadMenuItem();

             menuItem.Text = "NewItem1";

             contextMenu2.Items.Add(menuItem);

             RadMenuItem NewmenuItem = new RadMenuItem();

             NewmenuItem.Text = "NewItem2";

             RadMenuItem childItem = new RadMenuItem();

             childItem.Text = "childItem";

             NewmenuItem.Items.Add(childItem);

             contextMenu2.Items.Add(NewmenuItem);

             RadTreeView1.ContextMenus.Add(contextMenu2);

             foreach (RadTreeNode node in RadTreeView1.GetAllNodes())

             {

                 node.ContextMenuID = node.Level == 0 ? "ContextMenu1" : "ContextMenu2";

             }

         }

     }

  
  
  Thanks,
  Princy.
