Subscribe to the EndPrint
event of the document you are sending to the printPreviewDialog
control, then check the PrintAction
in its PrintEventArgs
argument.
Example:
private void buttonPrintPreview_Click(object sender, EventArgs e)
{
PrintPreviewDialog printDialog = new PrintPreviewDialog();
printDialog.Document = yourDocument;
yourDocument.EndPrint += doc_EndPrint; // Subscribe to EndPrint event of your document here.
printDialog.ShowDialog();
}
void doc_EndPrint(object sender, System.Drawing.Printing.PrintEventArgs e)
{
if (e.PrintAction == System.Drawing.Printing.PrintAction.PrintToPrinter)
{
// Printing to the printer!
}
else if (e.PrintAction == System.Drawing.Printing.PrintAction.PrintToPreview)
{
// Printing to the preview dialog!
}
}
