| Gridlayout | Flowlayout | 
| GridLayout provides absolute positioning for controls placed on the page. | FlowLayout positions items down the page like traditional HTML. This approach results in pages that are compatible with a wider range of browsers. | 
| It is easier to develop a page with the absolute positioning as the control is placed any where according to the requirements. | If there is absolute positioning there are a number of DIV tags. | 
| Most of the developers use the visual basic as they are easy for positioning. | Most of the work is done through the tables. |
