PrintDocumentGridRenderer Class

Represents an object that renders a C1FlexGrid into a paged PrintDocument.

Inheritance
object
PrintDocumentGridRenderer
Namespace: C1.Win.FlexGrid
Assembly: C1.Win.FlexGrid.10.dll
Syntax
public class PrintDocumentGridRenderer
Public Class PrintDocumentGridRenderer
Remarks

This class may be used to print multiple grids, along with other custom content, into an existing PrintDocument object.

To use it, create one PrintDocumentGridRenderer for each grid you want to print. Then handle the document events and call the PrintPage(PrintPageEventArgs, bool) event for the renderers until the value of the CurrentPage property equals PageCount.

The code below renders two grids into a PrintDocument: 
// print two grids into an existing PrintDocument
private void button1_Click(object sender, EventArgs e)
{
  using (var dlg = new PrintPreviewDialog())
  {
    dlg.Document = this.printDocument1;
    dlg.ShowDialog(this);
  }
}

// event handlers for the PrintDocument object on the form
PrintDocumentGridRenderer _g1, _g2;
void printDocument1_BeginPrint(object sender, System.Drawing.Printing.PrintEventArgs e)
{
// create and configure grid renderer for the first grid
_g1 = new PrintDocumentGridRenderer(c1FlexGrid1);
_g1.Options = PrintGridFlags.FitToPageWidth | PrintGridFlags.ExtendLastCol;


// create and configure grid renderer for the second grid
_g2 = new PrintDocumentGridRenderer(c1FlexGrid2);
_g2.Options = PrintGridFlags.FitToPageWidth | PrintGridFlags.ExtendLastCol;
}
void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
// render first grid
if (_g1.CurrentPage < _g1.PageCount)
{
_g1.PrintPage(e);
e.HasMorePages = true;
}


// render second grid
else if (_g2.CurrentPage < _g2.PageCount)
{
_g2.PrintPage(e);
e.HasMorePages = _g2.CurrentPage < _g2.PageCount;
}
}
