Hi All,
this problem has been resolved. l post my solution here maybe can help you all at sometimes.
1.at the beginning of i encounter this problem. i doubt that the version Dev Express control are not supported by Test Complete. we used the v2013 but TC supported latest version to v2011 vol 2.5. so development team downupgrade it to v2011 vol 2.5. then it still cannot recognized by Test Complete normally.
2.based on above step. i made a small delphi application with same control. found that it works well by TC.
3. find out that the differences betweed this samll app with the Test system is even used the same version of the Delphi xe2 IDE.but the test system used Delphi xe2 was auto upgrade from Delphi 2009, and the small app was built from Delphi xe2 directly.
