我有一个带有扩展项目菜单的 Telerik radmenu。（见下图）
用户可以：
- 悬停菜单，显示子菜单，用户可以点击子菜单执行任务。
或者
- 单击 radmenu 并执行一项任务（即保存页面）。这用作快捷方式。
当用户在 radmenu 上单击或悬停时，会显示子菜单。但是我想在用户单击菜单时禁用子菜单。
这意味着，用户要么悬停菜单，然后打开子菜单
或者
单击菜单并执行相关操作，不显示子菜单。
谢谢您的帮助
这是使用的代码（ascx 和 ascx.cs）：
ascx:
<telerik:RadMenu ID="mnRightMenu" runat="server" Skin="Sapphire" EnableEmbeddedSkins="false" ExpandDelay="700" ClickToOpen="false"
OnClientMouseOut="OnClientMouseOut" OnItemClick="mnQuestion_MenuItemClick"
EnableScreenBoundaryDetection="false" GroupSettings-OffsetY="-10">
<DefaultGroupSettings ExpandDirection="Left" />
</telerik:RadMenu>
<script type="text/javascript">
function OnClientMouseOut(sender, args) {
args.get_item().close();
}
</script>
ascx.cs：
protected void mnQuestion_MenuItemClick(object sender, RadMenuEventArgs e)
{
string a = e.Item.Menu.ItemType.ToString();
MenuIndex = e.Item.Index + 1;
if (e.Item.Value.Contains("_item"))
MenuName = e.Item.Text;
else
MenuName = e.Item.Value;
RadMenuEventHandler handler = MenuSelected;
if (MenuSelected != null)
handler(sender, e);
}
