error:

cause Analysis :

VisualStudio 2012 (or) WebForm 4.5 development, many controls by default enable the unobtrusive Validationmode (so-called unobtrusive Validation, is a property of implicit authentication (related to the reference to jquery), but it is not assigned a value, programmer must be set manually. For example, the various validator used for data validation (the RequiredFieldValidator control used today), and the authorization and authenication settings, Because jquery is required to be called on the front-end for authentication, unobtrusive Validationmode is the default enable. If this property is not configured, an error is generated.

Solution:

One, in the case of allowing the program to reduce. The version of the framework, in the following ways:

<span style= "FONT-SIZE:18PX;" ><!--modified before--><system.web>  <compilation debug= "true" targetframework= "4.5"/>< HttpRuntime targetframework= "4.5"/> <!-Delete it--></system.web><!--modified--><system.web>  <compilation debug= "true" targetframework= "4.0"/></system.web></span>

B. Change the type of the Web. config profile setting unobtrusive Validationmode as follows:

<span style= "FONT-SIZE:18PX;" ><!--modified before--><system.web>  <compilation debug= "true" targetframework= "4.5"/>< HttpRuntime targetframework= "4.5"/></system.web><!--modified--><system.web>  <compilation Debug= "true" targetframework= "4.5"/>
 Third, this method may be somewhat complex, but also feasible. Here's how: 
1. Create a new scripts folder at the root of the website, add jquery-1.7.2.min.js and jquery-1.7.2.js to it (you can use a different version depending on your needs).
2. Add the Global Application class Global.asax file under the root directory and add the following code to the Application_Start event:
<span style= "FONT-SIZE:18PX;" >scriptmanager.scriptresourcemapping.adddefinition ("jquery", new Scriptresourcedefinition {Path = "~/scripts/ Jquery-1.7.2.min.js ", Debugpath =" ~/scripts/jquery-1.7.2.js ", Cdnpath =" http://ajax.microsoft.com/ajax/jQuery/ Jquery-1.7.2.min.js ", Cdndebugpath =" Http://ajax.microsoft.com/ajax/jQuery/jquery-1.7.2.js "});</span>
looked up a lot of information, all tried, these three methods are feasible, hope to help everyone, hey!
