Hello,
I want to modify one of the pages of my ASP.NET application where a field is being validated against SQL Server database.
The page has a field Equipment ID. When a user enters an ID the code has to check if such ID exists in the SQL Server equipment table. And the code re-post the page. I would like to eliminate the re-posting of the page so that the user does not see it. But simply display a text "Invalid ID" (if not found in the DB) or nothing if found.
I think in the past (and maybe still) AJAX was the technology to incorporate in the ASP.NET for this purpose. Should I learn how to use the AJAX for this purpose or there is a new (hopefully easier) technology for this?
TIA
