Allowing entry of a Carriage Return during data entry

[Mike Owen]

Hi,

I am using a ValidationExpression="^[a-zA-Z0-9 '.,]+$" on a
regularexpressionvalidator to restrict what is allowed to be entered in a
MultiLine textbox.

I would also like to allow the user to be able to enter a carriage return,
enabling them to be able to break up the text they enter, but unfortunately
despite all the additional bits that I have tried, e.g. adding \r between the
2 square boxes in the ValidationExpression, nothing seems to work.

How would I change the expression above to allow a CR to be entered? (I
have just thought should I be adding CR & LF not just a CR?).


Thanks, Mike.

hi Mike, if your looking to break into a newline then just a carriage return
wont suffice. along with \r issue a line feed also, so your expression will
be \n\r for allowing a break into a newline.

ValidationExpression="^[a-zA-Z0-9',.\n\r]+$"
