Help me identify which Asp.net tool i can use to achieve this(On this image i uploaded). If possible refer me to a tutorial that would help me achieve something like this. Your effort is highly appreciated. Thanks!

The only thing is that a datagridview is for winforms, not web forms. I've taken a look at your example, and i'm not aware of any third party controls you can use to get you exactly to that point. I'd say if you are comfortable with asp.net controls and html, you can build it from scratch on your own.

if you have some time on your hands, you can do this with a table (html or asp.net), some additional asp.net controls that you bind to your datasource, and some client side javascript and maybe ajax so you can move between the tabs and send/get data from the server without having to refresh the page each time.
