Demand: A similar RadRichTextEditor printing method that requires a print event

[zhijun]

RadRichTextEditor prints the code as follows:

                     RadPrintDocument document = new RadPrintDocument();
                     document.PrintPage += (s, e) => { action?.Invoke(); };
                     richTextEditor.PrintPreview(document);

Does RadSpreadsheet have such a Print/PrintPreview method?

Hello,

RadSpreadSheet have both the Print and PrintPreview methods. You can check the following documentation article: https://docs.telerik.com/devtools/winforms/spreadsheet/features/printing.

I want the Print/PrintPreview method to pass a RadPrintDocument object that records whether the user printed the document.

Hello,

Thank you for writing back.

Printing in the spread control is handled slightly different compared to how printing is implemented our other controls. Actually, RadSpreadSheet is also working with RadPrintDocument objects, however, these objects are created dynamically and they are not exposed publically. I have logged a feature request in our feedback portal, here: ADD. RadSpreadsheet - expose an API notifying that a print or print preview job is underway. I have also updated your Telerik points. We will do our best to fix the issue in the R2 2018 release.

For the time being, you can use the workaround below handling the PrintPreview method: 

private void button1_Click(object sender, EventArgs e)
{
    RadPrintDocument printDocument = new RadPrintDocument();
    IPrintable printManager = typeof(RadSpreadsheetElement).GetProperty("PrintManager", BindingFlags.Instance | BindingFlags.NonPublic).GetValue(this.radSpreadsheet1.SpreadsheetElement) as IPrintable;
    printDocument.AssociatedObject = printManager;

    printDocument.BeginPrint += PrintDocument_BeginPrint;
    printDocument.PrintPage += PrintDocument_PrintPage;
    printDocument.EndPrint += PrintDocument_EndPrint;
    printDocument.QueryPageSettings += PrintDocument_QueryPageSettings;

    SpreadsheetPrintPreviewDialog printPreviewDialog = new SpreadsheetPrintPreviewDialog(printDocument);
    printPreviewDialog.ThemeName = this.radSpreadsheet1.ThemeName;
    printPreviewDialog.ShowDialog();
}

private void PrintDocument_QueryPageSettings(object sender, System.Drawing.Printing.QueryPageSettingsEventArgs e)
{

}

private void PrintDocument_EndPrint(object sender, System.Drawing.Printing.PrintEventArgs e)
{

}

private void PrintDocument_BeginPrint(object sender, System.Drawing.Printing.PrintEventArgs e)
{

}

private void PrintDocument_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
}

I hope this helps. Let me know if you need further assistance.
