Go Up to Display Controls

The taskbar component provides control and information for your application in the Windows taskbar, for Windows 7, Windows 8 or Windows 10.

Using taskbar buttons, you can:

  • Show / update the progress of a specified progress bar in the taskbar button.
  • Display several different color states representative of the associated progress bar.
  • Overlay images on the application taskbar icon.
  • Add multiple buttons on the thumbnail preview of the application in the taskbar.
  • Register your 'tabs' (forms) to display more than one image in the taskbar preview.
    You can show the form as-is in the preview, or clip a region of the form, or generate a new image and display it.

To use the taskbar component and show the taskbar features properly:

  • The application must be running on Windows 7, Windows 8 or Windows 10.
  • A Windows Aero Theme has to be enabled (not included in Windows 7 Home Basic or Windows 7 Starter).

Use the ProgressMaxValue and ProgressValue properties to display the progress associated with the application:


The progress indication can have different colors depending on the state of the application. You can set the color using the ProgressState property:
