The zoom button enables users to maximize the detail View, so that it occupies an entire grid control’s region. In Card Views, the Zoom button is displayed at the View’s top right edge.
Clicking the zoom button maximizes the detail View while hiding all the other Views including the master. The button’s image now displays an ‘X’ sign to indicate the View is maximized.
The following table lists the main properties that affect element appearance.
For Grid Views and their descendants, use the GridViewAppearances.HeaderPanel property.
For Card Views, the Zoom button’s appearance depends upon the current paint scheme.
Custom Draw Event
For Grid Views and descendants, use the GridView.CustomDrawRowIndicator event.
A root master View’s GridOptionsDetail.AllowZoomDetail property must be set to true.
