推荐答案

我的解决方案是在用户控件中公开事件并从父级附加方法。

My solution for this would be to expose the event in the user control and attach a method from parent.

这个事情将在我完成的事件处理的帮助下完成我的下面的代码。

This thing will be done with the help of event handling that i have done i the folowing code.

GridView gv = (GridView)UserControl.FindControl("gridview1");
       gv.RowCommand += new GridViewCommandEventHandler("name of the event you want to call from parent page");

您可以尝试

this.NamingContainer

而不是

this.Page

我会这样做：< br $>

and I would do it like this:

MyPageName objMyPageName = this.NamingContainer as MyPageName;

if(objMyPageName != null)
{
   objMyPageName.CustomMethod();
}
