Regular expression: limit number of characters

I have a textbox and need to limit number of characters in it (no more than 1000).
This is the regular expression i have: ^.{0,1000}$
it works great until there is a newline in a textbox (when I hit enter). If there is newline in textbox it shows me the warning "you have more than 2000 characters". Is there workaround of this issue.

Set the RegexOptions.SingleLine flag.

Alternatively, you could explicitly include newlines in the regex: ^(\n|.){0,1000}$

. doesn't match all characters (i.e. newlines), so you can use two characters groups to get all characters, like this:

^[\s\S]{0,1000}$
