Align controls where the generated HTML control is positioned horizontally within its parent HTML element. 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 individual of the items within the grid generated to position them into rows.  

Align indicates the desired value of the Align option of the HTML tag for the generated control. 

The default value of Align is haDefault, which means the web browser that reads the HTML document horizontally positions the control wherever it wishes.
