如果继承自定义控件里的event

[stevenhzhang]

譬如：我用vb.net写了一个 Ca.ascx，里面有一个Calendar

我在 home.aspx 里面调用这个ascx <uc1:Ca ID="Ca1" runat="server" />
我想给Ca加一个触发Changed，当ascx里Calendar的SelectionChanged，主程序的Changed也相应响应类似 <uc1:Ca ID="Ca1" Changed="Ca1_Changed" runat="server" />

我不知道应该怎么在ascx里加。有人能帮忙以下吗？先谢了。

[真相重于对错]

ca.ascx.cs
.....
public delegate onchanged( object sender , someeventarge e );
public event onchanged changehandler;
protected Calendar1_SelectionChanged( object sender , eventarge e )
{
if(changehandler!=null)
changehandler(sender,e);
}

....
page.aspx.cs
proteced Ca Ca1;
....
Ca1.changehandler += new onchanged( ... )
随手写的，有错误怪

谢谢楼上，给了点提示。先后次序有点不对。

Public Delegate Sub SelectionChangedHandler(ByVal sender As Object, ByVal e As System.EventArgs)

Partial Class UserControls_WebUserControl
Public Event SelectionChanged As SelectionChangedHandler

Protected Sub Calendar1_SelectionChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles Calendar1.SelectionChanged
RaiseEvent SelectionChanged(sender, e)
End Sub
End Class
