Hi,
I'm using the regular expression validator (p. 306) to guard against a text box entry that is too long. The regular expression I'm using is "^.{1,20}$". This works quite well normally. However if I enter more than 20 characters in a text box AND the text in the textbox contains one or more carriage return characters (\n) the following occurs:
1. I obtain the expected notice that the expression is too long.
2. I shorten the expression to 20 or less characters and the validator continues to show that the expression is too long until I have erased all of the carriage return characters.

I have found jQuery expressions that can replace the carriage return characters with " " but I need to retain them and would like the length test to work even with the carriage return characters present. Is that possible?

Hi there,

White space is treated differently which causes the behavior you're describing. Does one of the regular expressions from this page work for you: http://forums.asp.net/t/1689377.aspx/1 ?
