推荐答案

如何为ASP中的用户控件处理事件.net页面 [ ^ ]

How to handle event for user control in asp.net page[^]

public partial class Test : System.Web.UI.UserControl

{

public event EventHandler buttonClick;

 protected void Button1_Click(object sender, EventArgs e)
    {
        buttonClick(sender, e);
    }

}

Then you can subscribe the event buttonClick at webpage to display the different information .

public partial class Test: System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    UserControlID.buttonClick+=new EventHandler(UserControlID_buttonClick);

}

    protected void UserControlID_buttonClick(object sender, EventArgs e)
    {
        Response.Write("hello,I am jack.");
    }

}
