Create custom control
You may wish to reuse a default control that you have placed in the design area and configured. You can do this by saving the configuration as a custom control.
To do this, right click on the body of the control. This will open up context menu, from which you should select the '‘define as custom'' option.
The application will then request a name for the control.
Once you have named it, the custom control will be added to the control type list.
