I think you are refering to some wronge data source.

-As you get data from db but on insert / update its not reflecting on db, also u are not getting any error.

please check your config. for database connection

Does it making insert / update on some other data source ?

Add this ....

<script type="text/javascript" language="javascript">

        Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);

        function EndRequestHandler(sender, args)
        {
            if (args.get_error() != undefined)
            {
                args.set_errorHandled(true);
            }
        }

</script>

Hi eldhokmgm

Uncaught Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500

You could learn the root of this issue below when you use UpdatePanel control,

The UpdatePanel control uses asynchronous postbacks to control which parts of the page get rendered. It does this using a whole bunch of JavaScript on the client and a whole bunch of C# on the server. Asynchronous postbacks are exactly the same as regular postbacks except for one important thing: the rendering. Asynchronous postbacks go through the same life cycles events as regular pages (this is a question I get asked often). Only at the render phase do things get different. We capture the rendering of only the UpdatePanels that we care about and send it down to the client using a special format. In addition, we send out some other pieces of information, such as the page title, hidden form values, the form action URL, and lists of scripts,

For further information about the analysis of Sys.WebForms.PageRequestManagerParserErrorException ,

With regards

all data and showing in the pages but i cant update and save new data

What kind of database do you use?

When you run website from VS, the website runs under your Windows account permission which is most likely administrator.

When you run website from IIS, website runs as IIS guest user which would not have permission to write database by default.
