SUMMARY

This article describes how to update fields in a screen while a user is scrolling through a list box that is based on a database field (a "prompt field" in the Screen Builder in FoxPro 2.x for Windows).

MORE INFORMATION

FoxPro 2.x for Windows

When a list box is set up as a prompt field in the Screen Builder or is based on a POPUP defined with PROMPT FIELD, scrolling through the list box also moves the record pointer in the database. In order for other @ ... GET fields on the screen to be updated as the record pointer is moved, insert the following code in the WHEN clause of the list box: 

   SHOW GETS
   RETURN
The WHEN clause is reexecuted as the user moves through the list box, which allows this code to update those fields.

Visual FoxPro for Windows

In a form, use the following code for the list box's WHEN clause: 

   THISFORM.REFRESH
   RETURN
