Custom server control: specifying event declaratively on ASPX code

问题

I'm currently working on several custom ASPX server controls. Of course these controls do also expose events. Now one possibility is to register a handler in the code, more specifically in the page where the custom server control resides...like

protected void Page_Load(object sender, EventArgs e)
{
   myCustomControl.Click += new ....
}

But how do I have to expose the event in my server control code s.t. I can declare these event handlers directly on the ASPX code (from the Property Editor), similar as you can do it on the Button's click event??

Thanks a lot,

Juri

回答1:

You do just that...

If you have a public event on your ASCX Control called PropertyChanged

then it'll be available declaritively on your Control as OnPropertyChanged

<ctl:MyControl ID="abc" runat="server" OnPropertyChanged="abc_PropertyChanged" />

Have you tried just making them public events?

This MSDN article does a good job explaining how to do this unfortunately it is more complicated than it seems like it should be.
