ASP.Net Ajax $common.parseUnit function

Im trying to adapt some code that I have found online that uses this function..

$co开发者_C百科mmon.parseUnit

Does anyone know where it lives as at present I am getting an "$common.parseUnit is undefined" error when the code hits that line.

Thanks.

$common.parseUnit() is exposed by the common scripts of the ASP.NET AJAX Control Toolkit, so you probably need to install that toolkit.

EDIT: If you have the toolkit installed, check if you have properly referenced the common toolkit scripts, either by decorating your extender classes with:

[RequiredScript(typeof(CommonToolkitScripts))]

Or by explicitly adding the reference to your ToolkitScriptManager:

yourToolkitScriptManager.Scripts.Add(new ScriptReference("Common.Common.js",
    "AjaxControlToolkit"));
