I have a question about button inside the gridview. As the title says, I designed a gridview with a button inside. Whenever I trigger the button, it always binding the gridview before it can reach the button event.

Say, `onLoad` page, I pull data and bind them to a gridview, then I would like to do a mass update which will be triggered by the button inside it. If i put `!IsPostBack`, it never triggers the button event, which means it always has to read the data bind them into gridview again then execute the button event.

**Problem is**, I have a huge data and it takes much time to update because of it. I am wondering if there are any ways to **trigger the button** event **without rebinding** the gridview again? Is it because of the button inside the gridview so it is necessary to rebind again before it could read the button event? 

Any suggestion would be really appreciated.
