Here's how to fix it

Method One:

Modify the Web. config file as follows:

<configuration>

<appSettings>

<add key= "Validationsettings:unobtrusivevalidationmode" value= "None"/>

</appSettings>

......

</configuration>

Method Two:

Modifying the global Application class Global.asax

1. Add assembly reference: Using System.Web.UI;

2. Add the following code to the Application_Start method of class global:

ScriptManager.ScriptResourceMapping.AddDefinition ("jquery",

New Scriptresourcedefinition

 {

Path = "~/scripts/jquery-1.7.2.min.js",

Debugpath = "~/scripts/jquery-1.7.2.min.js",

Cdnpath = "Http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.4.1.min.js",

Cdndebugpath = "Http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.4.1.js"

 }

);

3. Create a new Scripts folder in the solution project directory and put the file jquery-1.7.2.min.js

The following two methods are for informational purposes only and are helpful for understanding the causes of errors!

Method Three:

Add the following code to the Page_Load method of the ASPX page:

Unobtrusivevalidationmode = Unobtrusivevalidationmode.none;

Method Four:

Add the file AspNet.ScriptManager.jQuery.dll to the project reference. This method resolves the error, but causes the validation control to not work.
