Multiline Textbox - Automatically Break To Next Line After 100 Characters

May 2, 2012

I've had an "interesting" request .

1) Is it possible, in a multiline textbox, to automatically break to the next line after 100 characters?
2) If not, is it possible to parse the enter key as entered by the user to break the line in the code behind?

Some additional info:

The person requesting this does not think that the user should use a single line textbox limited to 100 characters and click an "Add Line" button to store that field in a table.

The person requesting this is of the belief that a DEC Alpha-based system that currently does this can be replicated on the web.

How To Validate The Maximum Allowed Number Of Characters In A Multiline TextBox

Mar 30, 2010

it's a multiline TextBox the MaxLength property does not work. At the moment I only see the option to use a CustomValidator with checking TextBox1.Text.Length on server side and perhaps in addition some Javascript client side validation.But isn't there a simpler way to do this, using the standard ASP.NET validators (RegularExpressionValidator, RangeValidator, CompareValidator, etc.)

How To Prevent Tab Characters From Being Pasted Into A Textbox

Dec 24, 2010

I'd like to have an asp.net textbox that people can paste content into and it works like notepad, i.e. no formatting or special characters will get entered. I take text and pass it to a web service which manipulates it and converts it into a tab delimited file. The problem I've experienced is sometimes people copy from MS Word and paste that content in and somehow even the tab characters etc. get passed to the web service. I run routines now to strip that information out but it would be so much easier if the textbox on the web page didn't capture anything but the text itself, i.e. visible characters (numbers, letters, punctuation).
