We are evaluating TestComplete to test our application. My application uses third party controls like Infragistics and MindFusion Controls. I tested TestComplete against the Infragistics controls and found that it recognizes almost every control used in my application (with some exceptions though).
Regarding Mindfusion controls, it does not recognize these controls. My application uses DiagramView class and Diagram class of MindFusion.

TestComplete does not provide special support for MindFusion controls. Try using the controls' native methods which are available to TestComplete when the application is compiled with debug information. Also, I recommend that you see the following FAQ article .
