Answer 1

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

never use jquery script it will go to server end every time which give bad effect to your application perfomance just add tag(mention above) in web config

within configuration tag

Answer 2

protected void Page_Load(object sender, EventArgs e)
{
    this.UnobtrusiveValidationMode =System.Web.UI.UnobtrusiveValidationMode.None;
}

Just copy & paste in C# Code

Answer 3

See here

It looks like you have to either remove this line:

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

Or change it to this:

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

Which will disable it for you.

Alternatively you could add something like this to your Global.asax

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"
});

Hopefully this gets you squared away!
