Hello Appu,

To hide an item in the header context menu:

protected void Page_Load(object o, EventArgs e)
{
    RadGrid1.HeaderContextMenu.ItemCreated += new RadMenuEventHandler(HeaderContextMenu_ItemCreated);
}

void HeaderContextMenu_ItemCreated(object sender, RadMenuEventArgs e)
{
    if (e.Item.Value.Contains("CategoryID"))
        e.Item.Visible = false;
}

To insert new item in the context menu you could use the OnPreRenderComplete event

protected override void OnPreRenderComplete(EventArgs e)
{
    RadContextMenu menu = RadGrid1.HeaderContextMenu;
    RadMenuItem item = new RadMenuItem();
    ...
    menu.Items.Add(item);
    base.OnPreRenderComplete(e);
}
