Set User Interaction Behavior

The application end-user can navigate, select, and move thumbnails within the ThumbnailXpress™ control, between multiple ThumbnailXpress controls, and between multiple applications. The application establishes how the user will interact with the control, by setting the following ThumbnailXpress properties:

Enable User Interaction

ThumbnailXpress enables end-user navigation of thumbnails via user-generated events. To enable the ThumbnailXpress control to handle user-generated events, set the Enabled property.

Set Selection Behavior

The SelectionMode property specifies the behavior that is desired when an end-user selects a thumbnail.

Set Drag and Drop Behavior

To enable the end-user to drag and drop thumbnails within the ThumbnailXpress component, set IntraComponentThumbnailDragDropEnabled.

To enable the end-user to drag and drop thumbnails between multiple ThumbnailXpress controls, set InterComponentThumbnailDragDropEnabled.

To enable the end-user to drag thumbnails from the ThumbnailXpress component to another application, set EnableAsDragSourceForExternalDragDrop.

To enable the end-user to drag thumbnails from other applications into the ThumbnailXpress component, set EnableAsDropTargetForExternalDragDrop.

The Shift key must be held down during a drag-and-drop operation to move multiple selected thumbnail items.

Set Directory Drill Down Behavior

If DblClickDirectoryDrillDown is enabled, then when the end-user double clicks on a folder icon in the ThumbnailXpress component, the thumbnails of images within the directory will be displayed. This enables the end user to navigate through folder structures to locate thumbnails of interest.
