I am using Delphi 5 and I like to use LookupCombos to select data although there are times when you want to unselect the data. This creates a problem. I have been using cached updates on the lookup table to enter a record with a null value that I never post to the dataset. This way the lookup list has another selection in it to unselect the data.
I wish there was a control like DBLookupComboBox and DBComboBox in which you can mix the lookup data with entered TString data.
Please help if you can.
