Hi Guys,

Quick question : I have 2 forms : FORM1 and FORM2. In FORM1 i am trying to implemen a PRINT PREVIW button to work like the PRINT PREVIW button in FORM2.
Here is the delegate, event Starter() and Subscriber() lines.

public delegate void DelegatPrintPreview(object sender, EventArgs e);<br />        public static event DelegatPrintPreview EvenimentDelegatPrintPreview;<br /><br />        public static void StarterPrintPreview(object o, EventArgs ev)<br />        {<br />            if (EvenimentDelegatPrintPreview != null)<br />            {<br />                EvenimentDelegatPrintPreview(o, ev);<br />            }<br />        }<br />        public static void SubscribeToPrintPreview(DelegatPrintPreview pf)<br />        {<br />            EvenimentDelegatPrintPreview += new DelegatPrintPreview(pf);<br />        }

the question is : Where do i put the delegate(in the form with the same button or the other one )? and the same question with the Starter() and Subscriber() methods ?

Regards,
Alex

Firstly, you don't need to define that delegate. The EventHandler delegate has the same signature.

You'd want to stick your event handler in both forms, and implement each seperately. If they share the same code, put that in a common function and call that from both handlers.
