我在usercontrol webheader中有3个按钮我想在webfooters中调用3个不同的方法每个按钮调用不同的方法我怎么能处理，因为我把2个usercontrol放在页面上

Answer 1

您可以在事件和代表的帮助下轻松完成。

从WebHeader公开事件并在内容页面中订阅它。在WebFeader上调用要在WebHeader上调用的WebFooter方法单击。单击按钮后，请调用WebFooter的适当方法

//pseudo code

//WebHeader
public delegate void Button1Clicked(object[] args);
//raise this event when the button is clicked
public event Button1Clicked buttonClicked;

//WebFooter
public void Method1(object[] params); //for button 1 click



//In content page which holds both header and footer control
WebHeader.Button1Clicked+= new WebHeader.Button1Clicked (HandleClick);

public void HandleClick(object[] params)
{
    WebFooter.Method2(params);
}
