How to Set maxlength (character counter) for textbox in asp.net using jquery.
We learn in this article, how to set max length of multiple
textbox in asp.net c# with Jquery even at cut and paste. We have a Textbox
which has TextMode as "MultiLine". And we want to restrict the number
of characters to 1000 (key in and data paste), and also the div character counter
should reduce based on the characters.
