The amount of space available on the screen is more limited with IDC controls than with IDD applications. Large dialog boxes in particular do not work well with the limited space. In IDC controls, large dialog boxes are replaced with overlay panels that use the full control space and a clickable path in the title bar to navigate back to the starting panel.

As an example, here is the main display of the Hierarchy Manager control.

When the user selects an entity in the graph and chooses View Detail, a full panel overlay is used to display the entity information. The title bar of this panel consists of a clickable path showing the title of the main page and the current page. Clicking on the title of the main page returns to that view.
