VAlign controls where the generated HTML control is positioned vertically within its parent HTML element. VAlign indicates the desired value of the VAlign option of the HTML tag for the generated control. . If the adapter action button is included in the column of an adapter grid, this property has no effect unless the associated action has multiple items. It affects the position of the HTML controls for each of the individual items within the grid generated to position them into rows.  

The default value of VAlign is haVDefault, which means the web browser that reads the HTML document vertically positions the control wherever it wishes.
