PrintDialog.ToPage

[Administrator]

Using the GridControl, how can I set the ToPage property of the PrintDialog ?

(pd is a PrintDocument)

This give me 0

_print_dialog.PrinterSettings = pd.PrinterSettings

This give me 9999

_print_dialog.PrinterSettings.ToPage = pd.PrinterSettings.MaximumPage

This give me 0

_print_dialog.PrinterSettings.ToPage = pd.PrinterSettings.ToPage

Hi Stephane,

Sorry for the delay in replying. By default, the ToPage property will be zero for GridPrintDocument. You can follow the code snippet to set the property.

GridPrintDocument pd = new GridPrintDocument(gridDataBoundGrid1);
pd.PrinterSettings.FromPage = 1;
pd.PrinterSettings.ToPage = 2;

PrintDialog ptdlg = new PrintDialog();
ptdlg.Document = pd;
ptdlg.AllowSelection = true;
ptdlg.AllowSomePages = true;
ptdlg.PrinterSettings.PrintRange = System.Drawing.Printing.PrintRange.SomePages;
//ptdlg.PrinterSettings.FromPage = 3;
//ptdlg.PrinterSettings.ToPage = 4;
ptdlg.ShowDialog();

Also refer to MSDN Library ( http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemDrawingPrintingPrinterSettingsClassToPageTopic.asp ) for more details on ToPage property. Let us know if this helps

Thank for the answer. I think I did not express what I needed correctly. Is there a way to get the number of pages to print and set it in the "to" field of the PrintDialog.

ex: When I do a print preview, it will indicate that the grid is 10 pages long. When opening the PrintDialog, I want to see 10.

Thank

I tried this but it''s not accurate and it''s not direct.

Dim w, h, fw, fh, pages As Integer

w = pd.DefaultPageSettings.Bounds.Width
h = pd.DefaultPageSettings.Bounds.Height

fw = active_window.Grid.Model.ColWidths.GetTotal(0, active_window.Grid.Model.ColCount)
fh = active_window.Grid.Model.RowHeights.GetTotal(0, active_window.Grid.Model.RowCount)

''System.Windows.Forms.MessageBox.Show(w & ":" & h & "**" & fw & ":" & fh)
pages = CInt((fw / w) + 0.5) * CInt((fh / h) + 0.5)

Hi Stephane, Sorry for the delayed response, GridPrintDocument calculates the page details and draws the contents dynamically in the OnBeginPrint/OnPrintPage overrides. So, it is possible to get the page no only after showing the PrintPreviewDialog. Here is a demo sample. Let us know if you need any further information. Best regards, Madhan.

Do you know a way to call the OnBeginPrint without calling the print preview before ?

[Administrator]

Hi Stephane,

The OnBeginPrint only be triggered while Printing or during preview. We are currently working on a sample to calculate pages in a indirect way, which we will update you soon.

Best regards,
Madhan.

Any update ?

Hi Stephane,

Sorry for the delayed response. It seems tricky; I will update you the sample this week end.

Thanks for the patience.

Hi Stephane, Thanks for being patient. The easiest and fastest approach to calculate the number of pages is by calling the PrintPreviewDialog and cancelling it in the BeginPrint event of the PrintDocument. The performance is good, even the number of pages is large. Sample : Print Issue For more details on Printing : Printing in .Net with C# Best regards, Madhan

I have a better way of doing this. Instead of opening a PrintPreviewDialog, just call PrintDocument.Print(). Still hook to begin print event and cancel straight away as in the sample provided.

// Print code

GridPrintDocument pd = new GridPrintDocument(gridDataBoundGrid1);
pd.BeginPrint += new System.Drawing.Printing.PrintEventHandler(pd_BeginPrint);

pd.Print();

PrintDialog ptdlg = new PrintDialog(); ptdlg.Document = pd; ptdlg.PrinterSettings.PrintRange = System.Drawing.Printing.PrintRange.SomePages; ptdlg.AllowSomePages = true;
ptdlg.ShowDialog();

// End Print Code

// Begin Print Event Handler

private void pd_BeginPrint(object sender, System.Drawing.Printing.PrintEventArgs e)
{
e.Cancel = true;
}

// End Begin Print Event Handler
