PRB: List Box Choices Not Highlighted Properly

ID: Q127837

The information in this article applies to:

SYMPTOMS

In both FoxPro for MS-DOS and FoxPro for Unix, when you place a list box on a screen, the items in the list box are not highlighted until an item is selected from the list box.

WORKAROUND

Using the KEYBOARD command in conjunction with a variable that is evaluated in the WHEN clause of the list box object, have FoxPro highlight the first item in the list box to provide a visual indicator to the user that they are in a specific list box. See the More Information section for details.

STATUS

This behavior is by design.
