Hi. I am generating a PDF from the contenst of a radgridview using RadDocument. This is a feature which has been part of my application for a couple years and does not get tested much on my end because I don't usually make changes to it.

Recently I noticed that the header of my report has extra space in it, basically it looks like there is an extra blank line in between each line of text (there are 3 lines).

This is the code which generates the header:

var headtable = new Table(1, 2);

var table = new Table(1, 5);

var document = new RadDocument();

document.Sections.Add(new Telerik.Windows.Documents.Model.Section());

document.LineSpacing = 1;

headtable.CellPadding = new Telerik.Windows.Documents.Layout.Padding(0); ;

headtable.CellSpacing = 0;

//report header

document.Sections.First.Blocks.Add(headtable);

//col 1

var headCell = headtable.Rows.First.Cells.First;

headCell.Borders.All = new Telerik.Windows.Documents.Model.Border(BorderStyle.None, Colors.Black);

AddCellDataSpan(headCell, App.RunForName, Colors.Transparent, Colors.Black, Telerik.Windows.Documents.Layout.RadTextAlignment.Left);

AddCellDataSpan(headCell, "Run: " + DateTime.Now.ToString("M/dd/yyyy h:mm tt"));

AddCellDataSpan(headCell, "Range: " + App.startDate + " to " + App.endDate);

AddCellDataSpan(headCell, " ");

//col2

headCell = (TableCell)headCell.NextSibling;

headCell.Borders.All = new Telerik.Windows.Documents.Model.Border(BorderStyle.None, Colors.Black);

AddCellDataSpan(headCell, App.companyName, Colors.White, Colors.Black, Telerik.Windows.Documents.Layout.RadTextAlignment.Right);

AddCellDataSpan(headCell, reportname + " Report", Colors.White, Colors.Black, Telerik.Windows.Documents.Layout.RadTextAlignment.Right);

//AddCellDataSpan(headCell, " ");

What I am expecting to see, and I think used to see is basically 3 lines of text one on top of the other. But what I am getting is what looks like 6 lines of text with a blank in between each of my lines. Though I think it's actually a line spacing issue, I don't think a carriage return is being entered erroniously.

What am I doing wrong?

The empty line after the table is fine, but what I want to get rid of the is the empty lines in the cell. Each line of text is followed by an empty line, and all this is happening in a single cell.

Instead of adding each piece of text to the cell one at a time, I tried putting it all into a string and adding it that way, but the same thing happens. How do I get 3 lines of text into a cell, without an empty line in between them?

Here is the new code, I just commented out the second cell completely and for now I will ignore that one until the first cell is working.

//define text for header cell

string headerText = App.RunForName + Environment.NewLine;

headerText = headerText + "Run: " + DateTime.Now.ToString("M/dd/yyyy h:mm tt") + Environment.NewLine;

headerText = headerText + "Range: " + App.startDate + " to " + App.endDate;

//col 1

var headCell = headtable.Rows.First.Cells.First;

headCell.Borders.All = new Telerik.Windows.Documents.Model.Border(BorderStyle.None, Colors.Black);

AddCellDataSpan(headCell, headerText, Colors.Transparent, Colors.Black, Telerik.Windows.Documents.Layout.RadTextAlignment.Left);

//AddCellDataSpan(headCell, "Run: " + DateTime.Now.ToString("M/dd/yyyy h:mm tt"));

//AddCellDataSpan(headCell, "Range: " + App.startDate + " to " + App.endDate);

AddCellDataSpan(headCell, " ");
