Capture print dialog's cancel in silverlight printing

问题

Does anyone know if you can find out if the print dialog's cancel was clicked?

I've seen post and doc that say "EndPrint – Event fired when the printing is either completed or canceled. "

But I don't think that is the print dialog's canceled... I think the is if the print job is canceled.

thanks

Based on the documentation, I don't believe there's an easy way: http://msdn.microsoft.com/en-us/library/system.windows.printing.printdocument.endprint(v=VS.95).aspx

In particular:

The EndPrint event will not occur if the user cancels the print operation from the print dialog box. A BeginPrint event will always occur before an EndPrint event.

Apparently the EndPrint event is only to clean up in the case of the document actually printing, not in the case of canceling the print dialog.

回答2:

There is one way, if the 'PrintPage' event is not CALLED after you call 'printDocument.Print()' method that means 'Cancel' button was pressed by the user on print dialog.

hope it helps.
