ASP.NET – Making Asynchronous calls to the Server

Question

Hi,

Good morning.

We are building an ASP.NET website and in that we have one big page having 4 GridViews. Each grids have sorting feature enabled. We need to make an asynchronous call to the server for each grid (whenever a user clicks on a column of a grid view to sort) so that it renders fast (instead of full page getting refreshed each time).

Is there a best tutorial or web reference explaining making these asynchronous calls?

Thanks and Regards..

Answer 1

The easiest way to do this would be to wrap each grid in an UpdatePanel and let ASP.NET ajax handle the details.

Answer 3

This looks promising

You could also look into ASP.NET Ajax and the UpdatePanel -- only recommended for simple, low usage pages.
