I am populating a dropdown list using a select query:
There are no null values in the Tape table allowed. However, I would like for there to be a “none” selection option in the dropdown list with a “Selected Value” of -1 (i.e. no selection). Since that “none” selection doesn’t exist in the result set, I should probably be manually adding it in. But I don’t see any property of the dropdown list that can do that, so how could I go about it?
