In my asp.net project, there is a multiple line text box to let user input comments.
If user input a comment like below.
Thank you for your fax.
I'll reissue a check to you.
If you have any question, please call me at xxx-xxx-xxxx.
This comment will save as varchar into a SQL server table.
The problem is that once review this comment, three lines text will display like one line text as below.

How to fix it?
Browsers do not display white space characters, if the comments are displayed on a web page, you need to replace the newline character (\n\r) to an HTML newline (<br />)
