Custom server control: specifying event declaratively on ASPX code

Question

Hi,

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

Answer 1

Have you tried just making them public events?

Answer 2

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" />

Answer 3

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