A detail tooltip is a popup window that appears while hovering over the master-detail expand button of a master row. The tooltip displays captions of all detail Views associated with the master row. The end-user can click a caption to open the corresponding detail View.
The following table lists the main properties affecting element appearance.
By default, a detail tooltip displays the name of the corresponding master-detail relation. To change the display text, use the detail View’s BaseView.ViewCaption property or GridView.MasterRowGetRelationDisplayCaption event.
