I have a form with 2 tab controls on it. I want the user to be able to fill out a portion of tab 1, then switch to tab 2, then back to tab 1 to complete the remaining fields. My issue is that I have some required controls on tab 1 so that when the user moves to tab 2, an error message is displayed saying that there are required controls on tab 1 that are blank. Is there a way to move between tabs without Access checking for blank required controls when moving between tab controls? I have added error checking on the form before update event but it still checks for blank required controls when changing tab controls.
