动态将onserverclick事件添加到HtmlAnchor [英] Adding onserverclick event to a HtmlAnchor dynamically

问题描述

我有一个页面，想将onserverclick事件附加到我现有的页面上 HtmlAnchor.

I've got a page and would like to append the onserverclick event to my existing HtmlAnchor.

在设计视图中，我首先添加控件

In the design view I am first adding the control

<a runat="server" id="lnkFre" title="FR" onclick="document.getElementById('ctl00_hidLang').value='en-US';"><span>Français</span> </a>

我尝试过这样.

HtmlAnchor lnkFre = FindControl("lnkFre") as HtmlAnchor;
lnkFre.ServerClick += new EventHandler(lnkLang_Click);

此处lnkLang_Click是可从此页面访问的类中的事件.

Here the lnkLang_Click is an event in a class which is accessible from this page.

但是在运行时没有添加它.

But at runtime it is not being added.

我希望有这样的东西.

<a runat="server" id="lnkFre" title="FR" onserverclick="lnkLang_Click" onclick="document.getElementById('ctl00_hidLang').value='fr-BE';"><span>Français</span> </a>

这样有可能吗?还是请我推荐另一种方法.

Is this possible in this way? Or kindly suggest me another method.

非常感谢

推荐答案

这对我有用:

HTML

<a href="#A" runat="server" id="MyAnchor" onclick="alert('test');return true;">A</a>

隐藏代码

protected void Page_Load(object sender, EventArgs e)
{
     HtmlAnchor lnkFre = MyAnchor as HtmlAnchor;
     lnkFre.ServerClick += new EventHandler(lnkFre_ServerClick);
}

void lnkFre_ServerClick(object sender, EventArgs e)
{
     throw new NotImplementedException();
}

由于事件是动态绑定的，因此您显然无法在运行时看到标记，但它将调用服务器click事件.

You obviously won't be able to see the markup at runtime as the event is being bound dynamically but it will call the server click event.

也请注意onclick事件结束时的return(true);.服务器单击也必须触发.

Please also note the return(true); at the end of the onclick event. This is necessary for the server click to also fire.
