How to concatenate 2 fields from a dataset using LiveBindings?

问题

Is there a way to use the Live Binding Designer to concatenate 2 database fields to a component?

For example I have a MemTable for client, I want to concatenate the FirstName and LastName (fullname) to a label.

If there is a way to do that, I understand that the binding will be in one direction only (Database fields --> ComponentProperty).

回答1:

For something simple like this...you can use the AfterScroll Event of your Dataset

  if Dataset.Active and (Dataset.RecordCount > 0) then  
    label1.Caption :=Dataset.FieldByName('FirstName').AsString + ' ' + Dataset.FieldByName('LastName').AsString;

The easyest way to do with LiveBinding, is to use the CustomFormat property of the LinkFillControlToField :

Just use this format text as the example is the question: Self.Owner.FirstName.text + " " + Self.Owner.LastName.text
