Hello experts,

I am using Extended RichTextBox control from Microsoft.
Even if I check selection or specify page range  in Print Dialog the complete text is printed. I am unable to figure out a way to handle this. Can some one help me please with a sample code.

Thanks a lot in advance

Hi,

Substitute the methods printDoc_BeginPrint and printDoc_PrintPage in the example, with attached methods. This is a sample showing how you can print a selection. You'll may check PrintDocument.PrinterSettings.PrintRange what is going to be printed.

/peter



    private void printDoc_BeginPrint(object sender,
        System.Drawing.Printing.PrintEventArgs e) {
      // Start at the beginning of the text
      m_nFirstCharOnPage = myRichTextBoxEx.SelectionStart;
    }
 
    private void printDoc_PrintPage(object sender,
        System.Drawing.Printing.PrintPageEventArgs e) {
      // To print the boundaries of the current page margins
      // uncomment the next line:
       e.Graphics.DrawRectangle(System.Drawing.Pens.Blue, e.MarginBounds);
 
      // make the RichTextBoxEx calculate and render as much text as will
      // fit on the page and remember the last character printed for the
      // beginning of the next page
       m_nFirstCharOnPage = myRichTextBoxEx.FormatRange(false,
                                               e,
                                               m_nFirstCharOnPage,
                                               myRichTextBoxEx.SelectionStart+ myRichTextBoxEx.SelectionLength);
 
      // check if there are more pages to print
      if (m_nFirstCharOnPage < myRichTextBoxEx.SelectionStart + myRichTextBoxEx.SelectionLength)
        e.HasMorePages = true;
      else
        e.HasMorePages = false;
    }
