You can't do that in a web site: you have to use Javascript and HTML objects to interact with the user, you don't try and get an immediate response in C# before continuing.

See here: Javascript confirm from code behind using C# | The ASP.NET Forums[^] - it shows one way to do it.

Thanks For your Reply. My project is a Content management where control are created dynamically. So to apply with Javascript and HTML Object looks difficult

}
}
});

You can't call code like that, a .cs file is simply something your compiler uses to generate code, it doesn't (shouldn't) exist on the server and if it does it is just a text file. You'll need to create a WebMethod and you can call the web method using ajax. Google "asp.net c# call webmethod from jquery" and you'll find examples.
