Need data edit,update and delete in the gridview

Hi friends,

I am facing a common problem which everyone already faced but I need to know is there anything new comes with this issue?

My problem is I want to Edit, Update and Delete data in gridview in multiple column. I can do the edit , update,cancel and delete but what I want is I dont want this button to perform this. I mean when I load data in gridview the data will show in edit mode and when I edit any dat, the update will occur instantly in the sql server database. 

Is there anything new development comes? whatever it is if its ajax or java script or something else please give me detail.

Thanks for reading my post.

Regards
