Which GridView event to use when updating?

I have a GridView with ItemTemplate and EditTemplate. There is some text boxes in EditTemplate. I want to update records myself using E开发者_如何学GoditTemplate controls. Which event of GridView I should use? If I use Telerik's RadGrid then what event is better?

For GridView, probably the RowUpdating event which is fired when the user clicks whatever button has the Update command argument.

For RadGrid, it looks like they also provide a UpdateCommand event you can subscribe to to save data by hand.
