You can try something like that:

Protected Overloads Overrides Sub OnPreRenderComplete(ByVal e As EventArgs)Dim menu As RadContextMenu = RadGrid1.HeaderContextMenu
    Dim item As New RadMenuItem()
    item.Text = "Format"
    item.Attributes("ColumnName") = String.Empty
    item.Attributes("TableID") = String.Empty
    BuildColumnsMenu(item, RadGrid1.MasterTableView)
    menu.Items.Add(item)
    MyBase.OnPreRenderComplete(e)End Sub
