About Support

TestComplete can recognize Developer Express ExpressVerticalGrid 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 ExpressVerticalGrid ver. 3.3, 3.41, 3.49, 11.1.4 - 15.1.4, 18.1.3, 19.1.2, 20.1.3, 21.1.2.


In order for TestComplete to be able to work with Developer Express ExpressVerticalGrid 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 Implementing Debug Info Agent™ Support in Applications. 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 | ExpressVerticalGrid group of your project’s Object Mapping options. By default, this group contains the following items:

    • TcxVerticalGrid
    • TcxDBVerticalGrid

    You can also command the test engine to recognize custom controls as Developer Express ExpressVerticalGrid controls. See below for information about this.

  • Support for the control is implemented by the Delphi and C++Builder Application Support and Developer Express Control Support plugins. These plugins are installed and enabled automatically as part of the TestComplete Desktop module.

    If you experience issues when working with the controls, select File > Install Extensions from the TestComplete main menu and check whether the plugins are active. (You can find the Delphi and C++Builder Application Support plugin in the Desktop group and the Developer Express Control Support plugin in the Common group.) If the plugins are not available, run the TestComplete installation in the Repait mode.

Recognizing Custom Controls

To command TestComplete to recognize your custom controls as Developer Express ExpressVerticalGrid controls:

  1. Open your project’s Object Mapping options.

  2. Add the control’s class name to the Developer Express Controls | VCL | ExpressVerticalGrid group.

    If you do not know the control’s name, you can ask the control’s developers, or you can view the control’s ClassName property in the Object Browser panel. As an alternative, you can click Add From Screen and select your custom control on screen. TestComplete will retrieve the control’s class name and add it to the selected mapping group automatically. For detailed information, see Object Mapping.

Once the control is mapped, it gets all the properties, methods and actions specific to the Developer Express ExpressVerticalGrid 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 ExpressVerticalGrid 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:
