You just spent hours building a spectacle of a DUI form. You have close to 100 fields and labels and, frankly, it's a work of art! You click the preview button and you see a blank screen. Your heart stops for a second, there's a silent scream and you panic a bit.
Rest easy, here's what's happening.
All of your fields and settings have been saved (assuming you've clicked the Save button at least once so far) but there is a quirk in the previewing of DUI forms. There are 2 conditions that will cause your DUI preview to appear as an entirely blank screen:
- Having any listbox that is not bound to a data source will cause the entire preview to appear blank.
- Having any drop list that is not bound to a data source will cause the entire preview to appear blank.
Any label without a caption will not appear on the preview. (But this doesn't impact other fields on the DUI.)
Your preview will appear as expected once your drop lists and list boxes all have a data source selected.
