我在ASP.NET webusercontrol中有一个html超链接，我将runat服务器属性添加到html超链接并触发onserverclick事件以从C＃文件后面的代码处理它，但是当事件触发时，href标记变为“javascript：__ doPostBack （'controlname $ linkId'，''）事件不会触发。

那么，我如何从服务器端获取事件？
问题在于“CausesValidation”
在控件上设置CausesValidation =“false”，它将从输出的控件中删除：javascript: __doPostBack('
在此页面的某个位置或此输出中包含的某个位置，您可能具有RequiredFieldValidator。一旦你向页面添加一个，你开始得到这个_doPostBack的东西，因为VS认为它应该首先被验证。
