Asp.Net菜单控件的“MenuItemClick”事件没有解雇 [英] Asp.Net Menu Control's "MenuItemClick" Event not firing

问题描述

Hello All，



我在母版页中使用Asp.Net菜单控件。我获取绑定菜单的数据来自Sql Server数据库。



如果我从菜单中选择一个子项，那么父项必须显示为选中状态。

为了实现这个功能，我试图在MenuItemClick事件中编写代码。但它没有开火。



感谢你的支持。



谢谢，

Rajesh

If I select a sub item from menu then parent item must be showed as selected.
To do this functionality i tried to write code in "MenuItemClick" Event. But its not firing.

Appreciate your support.

推荐答案

您使用的是NavigateUrl属性吗？如果在创建菜单项时设置NavigateUrl，页面将导航而不是触发单击事件处理程序。



当用户单击菜单项时，Menu控件可以导航到链接的网页或只是回发到服务器。如果设置了菜单项的NavigateUrl属性，则Menu控件将导航到链接页面;否则，它会将页面发回服务器进行处理。

Are you using the NavigateUrl property? If you set the NavigateUrl while creating the menu items, the page will navigate instead of firing click event handler.

When the user clicks a menu item, the Menu control can either navigate to a linked Web page or simply post back to the server. If the NavigateUrl property of a menu item is set, the Menu control navigates to the linked page; otherwise, it posts the page back to the server for processing.

尝试在asp：Menu标签中使用内联事件处理程序分配，例如：

Try using the inline event handler assignment within the asp:Menu tag like:

<asp:Menu OnMenuItemClick="MenuEventHandler" />

或您可以在.vb或.cs之后的代码中执行此操作，例如：

or you can just do that inside your code behind .vb or .cs like:

menu.OnMenuItemClick += Menu_MenuItemClick; // Attach event handler programatically

private void Menu_MenuItemClick(Object sender, EventArgs e)// MenuItemClick event handler
{
  //Your code...
}

< b style =color：Red>注意：上面的代码是C＃代码。您可以使用VB的 AddHandler ，在代码中附加事件处理程序。

Note: The code above is a C# code. You can make use of AddHandler for VB, to attach an event handler in code.
