DesktopRadioGroup.InitialValue

From Xojo Documentation

Design Property (as String)

This DesktopRadioGroup property can only be set in the Inspector and is not available in code.

A list of the default radio button captions separated by returns.

Notes

This property is unreadable at runtime because the list is removed from memory once the control is created. You can set a default value for the control by populating the RadioGroup with InitialValue and setting the default value with SelectedRowIndex.
