About Support

TestComplete can recognize Developer Express QuantumGrid controls in Delphi and C++Builder applications. It provides special properties and methods that let you retrieve the controls data and simulate user actions on the controls (see below).

Supported Versions

Supported component versions: Developer Express ExpressQuantumGrid ver. 4 - 11.1.5, 11.2.3 - 14.1.5, 18.1.3.


In order for TestComplete to be able to work with Developer Express QuantumGrid controls, the following requirements must be met:

  • The tested Delphi or C++Builder application must be compiled with debug information. For information on the required compiler settings, see Preparing Application With QuantumGrid Controls for TestComplete. Contact your development team to learn whether your application is compiled with debug information.

    By default, Developer Express VCL components for C++Builder are compiled and distributed without debug information. Therefore, TestComplete cannot obtain access to properties and methods of such VCL controls used in the tested C++Builder Open Application. However, you can re-compile Developer Express VCL components for C++Builder with debug information and then use them in C++Builder Open Applications tested by TestComplete. To learn how to prepare these components for C++Builder applications, see Preparing Developer Express VCL Components for C++Builder Applications.
  • The control’s class name must be specified in the Developer Express Controls | VCL | QuantumGrid group of your project’s Object Mapping options. By default, this group contains the following items:

    • TcxGrid
    Note: As for custom views that are not inherited from any of the above-mentioned views, TestComplete can interact with them only via clicks and keystrokes. In addition, you can make use of QuantumGrid’s internal members to perform the desired actions over these custom views (see Working With Developer Express QuantumGrid - Overview).
  • A license for the TestComplete Desktop module.

  • The Developer Express Control Support plugin. This plugin is installed and enabled automatically.

    If you experience issues when working with the controls, select File > Install Extensions from the TestComplete main menu and check whether the plugin is active. (You can find the plugin in the Common group.) If the plugin is not available, run the TestComplete installation in the Repair mode.

Recognizing Custom Controls

To command TestComplete to recognize your custom controls as Developer Express QuantumGrid controls, open your project’s Object Mapping options and add the control’s class name to the Developer Express Controls | VCL | QuantumGrid group. The class name is specified by the control’s ClassName property. You can get the property value in the Object Browser panel. You can also choose the needed control from screen. For detailed information, see Object Mapping. Once the control is mapped, it gets all the properties, methods and actions specific to the Developer Express QuantumGrid control.

If the specified custom control does not fit the control’s type, then it may not properly respond to commands that TestComplete sends, so recording or playing back user actions over the tested control will cause errors.


When testing Developer Express QuantumGrid controls, you can use properties and methods specific to these controls, as well as properties and methods that TestComplete applies to tested objects, onscreen objects and window objects. For the full list of available properties and methods, see the following topics:

Typical Tasks
