Fires on the client side before a panel is made floating (undocked from a zone) and allows you to cancel the action.
The BeforeFloat event handler receives an argument of the ASPxClientDockManagerProcessingModeCancelEventArgs type. The following properties provide information specific to this event.
Gets or sets a value indicating whether the action which raised the event should be canceled.
(Inherited from ASPxClientProcessingModeCancelEventArgs)
|panel||Gets the panel currently being processed.|
Gets or sets a value that specifies whether the event should be finally processed on the server side.
(Inherited from ASPxClientProcessingModeEventArgs)
|zone||Gets the zone currently being processed.|
Write a BeforeFloat event handler to perform specific actions on the client side before each time the panel is made floating. You can use the event parameter's properties to identify a panel (ASPxClientDockManagerCancelEventArgs.panel) and a zone (ASPxClientDockManagerProcessingModeCancelEventArgs.zone) from which the panel is undocked.
Note that if the cancel property is set to true in the event's handler, the execution of the current command is canceled on the client side, and therefore no further processing is performed (that is the panel is not floated). If the command execution is not canceled (the cancel property is set to the default false value), further event processing depends upon the processOnServer property setting.
If the processOnServer property is set to false, the BeforeFloat event is completely handled on the client side, using the assigned JScript handler without a postback to the server.
Setting the processOnServer property to true indicates that the final processing of the event should be performed on the server side, and so a round trip to the server is required. During such a round trip, the corresponding server-side ASPxDockManager.BeforeFloat event is fired, which when handled, allows any desired server-side action to be performed.
