The example stores dashboard layouts using a DevExpress memory-based dataset ([TdxMemData]).
You can modify the application to use any other [TDataSet] descendant instead.
To review our data module implementation, see the following file: [uData.pas]/[uData.cpp].

Once you assign a new dashboard layout (and, optionally, a UI interaction state),
