Telerik RadGridView 右键菜单如何设置？

[b]问题[/b]：

解决方法：

private void  radGridView1_ContextMenuOpening(object sender,Telerik.WinControls.UI.ContextMenuOpeningEventArgs e)
{
for  (int i = 0; i < e.ContextMenu.Items.Count; i++) {

String contextMenuText = e.ContextMenu.Items[i].Text;

switch (contextMenuText) {

case "Conditional Formatting":
e.ContextMenu.Items[i].Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
e.ContextMenu.Items[i + 1].Visibility = ElementVisibility.Collapsed;
break;

case "Hide Column":
e.ContextMenu.Items[i].Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
break;

case "Pinned state":
e.ContextMenu.Items[i].Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
break;

case "Best Fit":
e.ContextMenu.Items[i].Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
break;
}
}
}
