the scenario is: i have a web app so when the user populate a date field and a text field and click validate it returns from sql data base a datatable. If this datatable has one record it fill all the fields in the page, however, if the datatable has more than one record I would like to make a window pop up with the records of the datatable so the user can chose one and it could return to the main page and fill all the fields.

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.
