Custom event not working when registered in an ASPX file

Question

I am trying to register a custom event I added to a user control. I can do this in code behind, but not in the aspx file.

What am I doing wrong?

Thanks!

The user control:

public delegate void MemberSelectedEventHandler(object sender, string fullMemberName);

public partial class WebUserControl1 : System.Web.UI.UserControl
{
    public event MemberSelectedEventHandler OnMemberSelected;

    protected void Button_OnClick(object sender, EventArgs e)
    {
        if (OnMemberSelected != null)
        {
            OnMemberSelected(this, "Peter");
        }
    }
}

This works (code behind of aspx page):

MyMemberControl.OnMemberSelected += new MemberSelectedEventHandler(MyMemberControl_OnMemberSelected);

But this doesn't (aspx page):

<scn:MemberControl OnMemberSelected="MemberControl_OnMemberSelected"  runat="server" ID="MyMemberControl" />

Answer 1

In the markup you need to prefix your event property with On so the page will know to register the event. Morzel had the answer though it's not stated explicitly.

<scn:MemberControl OnOnMemberSelected="MemberControl_OnMemberSelected"  runat="server" ID="MyMemberControl" />

OnOnMemberSelected should cause your handler to be invoked as expected.
