In this question, I asked about breaking a dataset into subsets, and got a good response. Now I have the opposite problem. I’ve got two different datasets, representing objects of two different subclasses of a common ancestor, and I need to have the same TDBLookupComboBox search both of them at the same time, using two properties, ID # and Name, that exist in the parent class.
A lookup field allows you to look things up from multiple source fields, but only in the same dataset, not two different ones. And a lookup control only allows you to specify one lookup field to search. Does anyone know how I could get data from both datasets to appear together in the combo box?
Create your own TDBLookupComboBox that takes multiple data sources. . . . I’ve created DB aware controls before (specifically drop down combo boxes). They are pretty easy to do and give you all the control you need.
