I was requested to develop a GridView like screen to allow easy DataEntry without the need to Click Save/Submit on each row of the GridView.
In other words, the user wants to edit the GridView Cells in a Web Screen as if he is editing Cells in MS Excel. The Data should be saved as soon as he will exit the cell by pressing the down arrow.
It think the only way to do that is to use Ajax technology, right ?
Maybe jQuery or ExtJS ?
