PrintPreviewDialog, How to specify the Page to de display, through code.

The PrintPreviewDialog expose a small control allowing the end user to
navigate to the various pages of the printed document, but neither in
PrintPreviewDialog, neither in PrintDocument can I spot a property allowing
to navigate to the various pages, with code. Am I missing something obvious,
or is it embedded in some other places, or...? My final goal is to
increment, decrement, the page to be displayed accordingly to the sign of
e.Delta from a MouseWheel event (exposed by PrintPreviewDialog), in addition
to PgUp/PgDown which are already doing it.

I think that's kind of pushing the UI paradigm. I have NEVER looked at an
up/down control and thought to myself "Gee, I wish I could change that value
with my mouse wheel."
 
Neither I, but some end user who used Adobe viewer (or something like that)
where the mouse wheel does just that.

It's possible that that's actually a listbox made so short that it looks
like an up/down control (which should be a capital offense). Just
thinkin'....

Hi Vanderghast,

PrintPreviewDialog is somewhat limited in what it can do.
My solution is to create a custom form that handle this functionality.
For example, drag a PrintPreviewControl and PrintDocument onto it. Set
the PrintPreviewControl.Document to this PrintDocument. Then
increment/decrement the PrintPreviewControl.StartPage through your
MouseWheel event.

Something like below;

public class PrintPreviewForm : Form
{
private PrintPreviewControl printPreviewControl;
private PrintDocument printDocument;

public PrintPreviewForm()
{
InitializeComponent();

MouseWheel += printPreviewForm_MouseWheel;
}

private void InitializeComponent()
{
printDocument = new PrintDocument();
printDocument.PrintPage += printDocument_PrintPage;
printDocument.EndPrint += printDocument_EndPrint;
printDocument.BeginPrint += printDocument_BeginPrint;

printPreviewControl = new PrintPreviewControl();
printPreviewControl.Document = printDocument;
printPreviewControl.Dock = DockStyle.Fill;

Controls.Add(printPreviewControl);
}

private void NextPage()
{
printPreviewControl.StartPage++;
}

private void PreviousPage()
{
if (printPreviewControl.StartPage > 0)
{
printPreviewControl.StartPage--;
}
}

private void printPreviewForm_MouseWheel(object sender, MouseEventArgs e)
{
if (e.Delta > 0)
{
NextPage();
}
else if (e.Delta < 0)
{
PreviousPage();
}
}

private void printDocument_BeginPrint(object sender, PrintEventArgs e)
{
// handle printing preparation
}

private void printDocument_PrintPage(object sender, PrintPageEventArgs e)
{
// draw something to print
}

private void printDocument_EndPrint(object sender, PrintEventArgs e)
{
// printing complete - release all graphics objects
}
}

Regards.

Okay, I take back my above statement.
PrintPreviewDialog does expose the PrintPreviewControl so you can
actually bind the MouseWheel event to PrintPreviewControl.StartPage;

private void printPreviewDialog1_MouseWheel(object sender, MouseEventArgs e)
{
if (e.Delta > 0)
{
printPreviewDialog1.PrintPreviewControl.StartPage++;
}
else if (e.Delta < 0)
{
if (printPreviewDialog1.PrintPreviewControl.StartPage > 0)
{
printPreviewDialog1.PrintPreviewControl.StartPage--;
}
}
}

Regards.
 
Thanks, I'll try that.
