Remarks

Note

This material discusses types and namespaces that are obsolete. For more information, see Deprecated Types in Windows Workflow Foundation 4.5.

ActivityPreviewDesigner is a sequential activity designer that displays all of its child activity designers in a strip that appears at the top of its design surface. When one of the child designers is selected, its representation is displayed in a preview window that the activity preview designer hosts below the strip. The ActivityPreviewDesigner has a preview mode and an edit mode. Preview mode allows the user to view the entire representation of the selected designer without scrolling; however, preview mode does not allow the user to modify the selected activity designer. Edit mode allows the user to modify the selected activity designer.
