Remarks
By default, a DocumentManager-based application displays the single Task Bar thumbnail for the entire form (see the figure below).
If the ShowThumbnailsInTaskBar property is set to DefaultBoolean.True, each non-empty Document will display its own thumbnail. Clicking it selects the corresponding Document. The figure below illustrates this behavior.
You can select the maximum number of thumbnails via the DocumentManager.MaxThumbnailCount property. If the number of thumbnails exceeds this value, only thumbnails for the most recently selected Documents will be displayed.
The ShowThumbnailsInTaskBar property is designed to be used within a TabbedView. Its proper functioning in any other View cannot be guaranteed.
Note
The ShowThumbnailsInTaskBar property requires a desktop that runs Windows Vista (minimum supported client)/Windows Server 2008 (minimum supported server) or a newer operating system version.
