ASP.NET

I want to disable the following item1 in the ContextMenu. But I din't find any relevant property for it in intellisense.

Telerik.WebControls.RadTreeViewContextMenu.ContextMenu contextMenu1 = new Telerik.WebControls.RadTreeViewContextMenu.ContextMenu();
contextMenu1.Name = "Menu";
Telerik.WebControls.RadTreeViewContextMenu.ContextMenuItem Item1 = new Telerik.WebControls.RadTreeViewContextMenu.ContextMenuItem();
Item1.Text = "Add New Item";
Item1.ID = "Add";

//Here i want to make this Item1 Enable false

contextMenu1.Items.Add(Item1);
RadTreeView1.ContextMenus.Add(contextMenu1);


Thanks in advance
