How Do I Set the Default Option for a Choice Control? (Magic xpa 3.x)
When you create a choice control, by default nothing will be selected, so the control will show as a blank, or as nothing selected. This can look strange to the user, who may expect the “first” item to be selected by default.
However, you can set the default option quite easily. Remember that a choice control is still a piece of data, and can be initialized like any other piece of data. In this example, the “Red” option (in the Display List property) is associated with ‘1’ (in the Items list property). So we initialize the Radio button virtual to ‘1’ in the Init column.
