Add the below code to the Application_Start method in your Global.aspx:
protected void Application_Start(object sender, EventArgs e)
{
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"
});
