Remarks
Using the ItemCheckMode property you can specify whether multiple item selection is enabled, and how gallery items can be checked. This property overrides the base BaseGallery.ItemCheckMode property to specify a different default value.
If single item selection is enabled, you can allow an end-user to close the PopupGalleryEdit popup window on a gallery item click. To accomplish this, set the PopupGalleryEditGallery.CloseOnItemClick property to true and the RepositoryItemPopupGalleryEdit.ShowButtons property to false.
If multiple selection is enabled, it is recommended that you save/discard the current selection by clicking the OK and Cancel buttons embedded in the popup window. The visibility of these buttons is specified by the RepositoryItemPopupGalleryEdit.ShowButtons property.
