I need to build a datagrid that auto-updates once new data is available. Basically, if multiple users are logged on to the application and one user uploads information, I would like to update the grid for all the user’s, without loosing user data. How do I go about accomplishing this please?

Hi Dollarjunkie

In this scenario, we need to check for changes on the server using async webservice calls through javascript or using timers with ajax, and you can also try the "Comet" technology:

Comet is a programming technique that enables web servers to send data to the client without having any need for the client to request it. It allows creation of event-driven web applications which are hosted in the browser.  -- wiki

Thanks.

There's a COMET grid control available now for asp .net developers:
