Hello Kenneth,

Could you please give us more details about your scenario to export the grid in PDF file, because there are few different approaches.

Option 1: using  ultraGridDocumentExporter1:

In this case you could set AutoSize = SizeColumnsandRowsToContent property

Option 2: using Documents.Report:

In this case you could modify the settings below :

report.Preferences.Printing.PaperSize = Infragistics.Documents.Reports.Report.Preferences.Printing.PaperSize.Auto;

report.Preferences.Printing.PaperOrientation = Infragistics.Documents.Reports.Report.Preferences.Printing.PaperOrientation.Auto;

report.Preferences.Printing.FitToMargins = true;

Infragistics.Documents.Reports.Report.Grid.IGridColumn column = grid.AddColumn();

column.Width =new Infragistics.Documents.Reports.Report.RelativeWidth(20);

column = grid.AddColumn();

column.Width =new Infragistics.Documents.Reports.Report.FixedWidth(100);

 Option 3: using UltraGirdPrintDocument:

In this case you could try to set

ultraGridPrintDocument1.FitWidthToPages = 1;

Let me know if you have any questions.
