Unless you have VFP8 and use BINDEVENT, this will not work at runtime. The only other option is to write a little PRG that will loop through all the pages on the form and the textboxes and use WRITEMETHOD to write code to whatever method you want in those textboxes.

I need to know if the user keyed through the text box controls at all. Can .setall be used for this? How to do it ?
