New Control - CasedTextBox - Sets TextBox Character Case

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).
  • Full Visual Studio .NET designer integration.


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.

Hi Jason,

If you first add a reference to the dotNetFreak.WebControls.UI.CasedTextBox assembly in Visual Studio (or WebMatrix) and then add:

<%@ Register TagPrefix="dnf" Namespace="dotNetFreak.WebControls.UI" Assembly="dotNetFreak.WebControls.UI.CasedTextBox" %>

to the top of your Web form and then add:

<dnf:casedtextbox id="txtName" runat="server" charactercasing="'UpperFirst"></dnf:casedtextbox>

to the page you should be set.

I will be uploading a new version in a couple of hours with another control, so feel free to grab that one.

If you have any problems, feel free to drop me a line.

Note: If you're using the version uploaded yesterday, the namespace has changed from dotNetFreak.WebControls.UI.CasedTextBox to dotNetFreak.WebControls.CasedTextBox. You'll need to update any existing pages etc.

Hey, this is handy - I use it to capitalise the first letter of addresses in a form I'm working on - what would make it perfect would be a casing option to capitalise the first character of each word, rather than just the first letter of the contents of the box, so that "my house" would be "My House" rather than "My house" as it is at present.

Still a great control though! :-D
