Input Behavior
The user input in RadGanttView is controlled by a special behavior class. The BaseGanttViewBehavior class is responsible for handling the keyboard, mouse, and context menu. It defines a number of methods which are virtual and custom implementations are easy to achieve as all of the base logic can be overridden. The behavior class is exposed by the RadGanttView.GanttViewBehavior property.
The following KB article features an example for creating a CustomGanttViewBehavior with custom logic handling the mouse and keyboard.
The table below lists all of the virtual methods related to the Mouse, Keyboard, and Context Menu in the BaseGanttViewBehavior class.
