Question

When I add the login control to the page, I got the following error. Could u help me ?

“WebForms UnobtrusiveValidationMode requires a ScriptResourceMapping
for ‘jquery’. Please add a ScriptResourceMapping named
jquery(case-sensitive).”

Answer 1

You need to have jQuery in your project and have something like this in Global.asax to register jQuery properly:

        ScriptManager.ScriptResourceMapping.AddDefinition("jquery", new ScriptResourceDefinition {
            Path = "~/scripts/jquery-1.4.1.min.js",
            DebugPath = "~/scripts/jquery-1.4.1.js",
            CdnPath = "http://ajax.microsoft.com/ajax/jQuery/jquery-1.4.1.min.js",
            CdnDebugPath = "http://ajax.microsoft.com/ajax/jQuery/jquery-1.4.1.js"
        });

Replacing the version of jQuery with the version you are using. You can also disable this new feature in web.config by removing the following line:

<add key="ValidationSettings:UnobtrusiveValidationMode" value="WebForms" />

Edit:

From the comments below, if the ValidationSettings:UnobtrusiveValidationMode is set to WebForms rather than removing it, you can change the value to None as shown below:

<add key="ValidationSettings:UnobtrusiveValidationMode" value="None"/>
