I have a SharePoint web part that I wrote in C# which is used to display SQL Server data based on user selections. I pull the data with a DataReader, fill a DataSet with it, and set that DataSet as the DataSource in a GridView and add that control to my page.

The only problem I'm facing is that line breaks in the data fields are not being rendered at all. I'm simply getting a block of text that ignores the breaks that are present in the database when it's rendered to HTML. I tried a regex:

Regex rgx = new Regex("\n");
string inputStr = Convert.ToString(dr[x]);
string outputStr = rgx.Replace(inputStr, "<br />");
newRow[ds3.Tables["Bobst Specs 3"].Columns[x]] = outputStr;

While that does detect and replace the newlines, I merely get the text "
" with no line breaks. I also tried changing my SQL query to something along the lines of:

SELECT REPLACE (fldCustomerName, '. ', '.' + @NewLineChar)

This apparently renders more newlines. I can see that they are present, because if I also insert the regex they are affected, but do not create line breaks. I'm not sure how to replace these, and what with, to get the lines to actually break.
