You can zoom the display in and out in four views in the DataWindow painter: the Design view, Preview view, Data View, and Column Specifications view. For example, if you are working with a large DataWindow object, you can zoom out the Design view so you can see all of it on your screen, or you can zoom in on a group of controls to better see their details.
To zoom the display in the DataWindow painter:

You can zoom the Design view, Preview view, Data View, and Column Specifications view.
Select Design>Zoom from the menu bar.
Select a built-in zoom percentage, or set a custom zoom percentage by typing an integer in the Custom box.
