Sorry for making so much noise to the Forums... just in case someone may have same issue. Here is the solution:
- Install Infragistics NetAdvantage Windows Forms 2009.2 on my computer
- In order for TestComplete to be able to work with my controls as with
InfragisticsWinGrid objects, the control’s class name must be specified in the Infragistics Controls | UltraGrid group of your project’s
Object Mapping options. So manually add my control's class name into Project Properties --> Object Mapping --> Infragistics Controls
Now my TestComplete is working perfectly with my tested application.
Good luck to everyone!
Nancy
