I am writing code to print from a FlowDocument.
PrintDialog printDialog = new PrintDialog();
bool开发者_运维技巧? result = printDialog.ShowDialog();
if (result == true)
{
FlowDocument fd = new FlowDocument();
fd.Blocks.Add(new Paragraph(new Run(String.Format("Message:\r\n{0}\r\n", txtMessage.Text))));
fd.PageHeight = printDialog.PrintableAreaHeight;
fd.PageWidth = printDialog.PrintableAreaWidth;
printDialog.PrintDocument((fd as IDocumentPaginatorSource).DocumentPaginator, "print test");
}
This code will print multiple columns in one page. How to avoid this?
I figured out. I need to set the ColumnWidth of FlowDocument.
fd.PagePadding = new Thickness(50);
fd.ColumnGap = 0;
fd.ColumnWidth = printDialog.PrintableAreaWidth;
In case, there is no printDialog involved (e.g. Writing a XML-File), this solution worked for me:
.PagePadding = New Thickness(50)
.ColumnGap = 0
.PageWidth = 21 * 96 / 2.54
.PageHeight = 29.7 * 96 / 2.54
.ColumnWidth = .PageWidth - .PagePadding.Left - .PagePadding.Right
