Question:
I am trying to populate an itembox control using DialogControlSet option 5, however it is causing some flashing. What Can I do to minimize the flashing behavior?Answer:
You are going to want to try to minimize the repopulation of controls or you will see flashing type behavior. I recommend fully populating the control then prompt the user for single item modifications. This doesn't cause the flashing.Something to keep in mind is you might need to temporarily disable the dialog when a longer background process is running. See DialogProcOptions option 1000.
Here is a code sample that helps show the flashing using option 5 that you were dealing with...
