Exposing an event handler as a control property

Hi all,

I have a custom server control that can contain one or more buttons.
I'm trying to expose an event handler as a property so that the buttons
can fire a click event when clicked. However, I'm getting the following
error:

Cannot create an object of type 'System.EventHandler' from its string
representation 'OnSubmit' for the 'OnSubmit' property.

My control's tag looks like this:

<stuff:MyControl OnSubmit="OnSubmit" Width="430"
runat="server">...</stuff:MyControl>

The property looks like this:

public EventHandler OnSubmit
{
get { return _onSubmit; }
set { _onSubmit = value; }
}

I've tried the property with and without a type converter without
success.

Any help would be much appreciated.

Thanks,

Paul

I'm not sure what you are trying to accomplish with this approach. You
probably only need a setter function which would simply fire the onSubmit
event not assign it to an event variable since that doesn't accomplish much.

I don't see a reason for a getter either. What are you getting? A fired
event? In that case the correct event handler is already invoked.
