CasedTextBox for .NET 2.0 Released

Unlike Windows Forms.NET, ASP.NET textbox controls seem to be missing the 'Character Casing' property which allows you to define the case of characters entered within a textbox.

Whilst it's fairly easy to replicate by hooking up some JavaScript to the 'onblur event', e.g.

txtEMailAddress.Attributes.Add("onblur", "this.value = this.value.toLowerCase();");

it becomes a bit of a pain having to enter this on every page. So, below is a simple ASP.NET control that basically does it for you. It simply inherits from the standard TextBox class and adds a new 'Character Casing' property allowing you to set the character case to one of three options:


Features:

  • CharacterCasing property to set the case to upper (all characters uppercase), upper first (only the first character uppercase) or lower (all characters lowercase).
  • Tested in IE6 & IE7 (PC), IE5 (Mac), FireFox 2 (PC & Mac), Safari 2 (Mac), Safari 3 (PC), Opera 9 (PC).
  • Full Visual Studio .NET designer integration.
  • Works in a 'ViewState Disabled' environment. 
  • Compatible with Medium Trust environments.

Simple Online Demo


Usage:

Simply download, add to your toolbox, drag 'n' drop to your page and set the property using the property grid.


Licensing & Download:

Free for both personal and commercial use, however please consider donating!

You may also redistribute the control royalty free, providing that you don't charge for it. Also, if you intend to distribute the control as part of an application which is publicly available it would be nice to know, although this isn't a requirement.

To download, please visit the 'Downloads' area.


Help & Support:

Please post in the forum.

  • Control failed to change the character case in some browsers - Fixed.
  • JavaScript is now embedded as an include rather than outputted into the Web page.

  • UpperFirst now converts the first character of every word to uppercase (ideal for addresses).
