Printing into a PrintPreview Control II
This follow-up corrects an oversight in the original PrintPreview sample for TX Text Control. After initializing the PrintPreviewDialog with a custom PrintController, the Activated event handler must replace it with a StandardPrintController so the dialog print button works.
In this sample, I explained how to print into a .NET Framework PrintPreviewDialog control.

A customized PrintController has been derived from the PrintController class. But I forgot to tell you to reset the PrintController after initializing the dialog. This is important, because the dialog provides a button to print the content to the specified printer directly. If the PrintController is the inherited one, its content will not be printed.
Therefore, we have to pass a new PrintController, after the dialog has been initialized. We can attach an Actived event where the dialog will be opened:
pp.Activated += new EventHandler(pp_Activated);In the event, we will create a new PrintController:
void pp_Activated(object sender, EventArgs e)
{
pp.Document.PrintController = new StandardPrintController();
}The PrintPreviewDialog must be accessible in this sample:
private PrintPreviewDialog pp = new PrintPreviewDialog();Related Posts
