All controls included in the ASPxDocking Suite (such as ASPxDockPanel, ASPxDockZone and ASPxDockManager) contain advanced client-side and server-side events. These controls allow you to control the behavior of dock panels and zones.

Typical end-user actions (such as drag and dock actions) invoke common events for all key elements of the panel docking functionality.

StartDragging and EndDragging events, specific to ASPxDockPanel ( StartPanelDragging and EndPanelDragging specific to ASPxDockManager), allow you to respond to the corresponding end-user actions performed on a panel.
BeforeDock and AfterDock events are common for ASPxDockPanel, ASPxDockZone and ASPxDockManager. They fire before and after a panel is docked to a zone, which allows you to cancel panel docking if required.
BeforeFloat and AfterFloat events are common for ASPxDockPanel and ASPxDockManager. They fire before and after a panel is undocked from a zone, which allows you to cancel the action if required.

The table below lists available client-side and server-side common docking events.

Event	Dock Manager Events	Dock Zone Events	Dock Panel Events
