>The Valid() code calls the form refresh, to update the text to the right of the drop-down. The Refresh() code for the text box performs a look-up, to set the description of the code. If I cause the application to pause at the end of Refresh(), the combo still displays the correct code. When the Refresh() exits, the combo box is cleared.

>I just now changed the Valid() code to call the text box Refresh() directly, to prevent any other refresh from firing. I can confirm the DisplayValue property by showing it in a WAIT WINDOW, after all of the code has been run, at the end of the Refresh(). However, the combo box is still being cleared after the Refresh() exits.

try this ( it is complex explain all ):

* valid
this.init
this.value = this.value
textbox.refresh
