Reloading the Design Canvas while using custom controls

In the process of designing an inherited control, a user control, or a form that contains such custom controls, you might modify the contents or properties of the controls as you work. Depending on whether the element you modify is more than one hierarchical level removed from the base container, you might not see the changes on the base container until you save and reload the design. For convenience, Progress Developer Studio for OpenEdge provides a Reload Design Canvas command, accessible from the Design menu or the Visual Designer context menu.

To make sure that changes to hierarchically nested elements appear on the base container, use the following procedure:

Save the base container.
Make the desired changes to nested elements, directly editing their classes.
With focus on the design of the base container, select Design > Reload Design Canvas or right-click and select Reload Design Canvas. You are prompted to save the container class if you have not done so.
