DockManager.StartSizing Event

Enables specifying whether end-users can resize the dock panels.

Namespace:DevExpress.XtraBars.Docking
Assembly:DevExpress.XtraBars.v17.1.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type StartSizingEventArgs containing data related to this event.

The following StartSizingEventArgs properties provide information specific to this event.
Property Description
Cancel Gets or sets whether the operation performed on the processed panel should be cancelled.
Panel Gets the processed dock panel.
SizingSide Gets the edge of the dock panel which is being dragged.

Expanded Remarks

End-users can resize dock panels by dragging their borders. The StartSizing event fires immediately after an end-user has pressed the mouse button while the mouse cursor is located over a panel's border.

The event parameter's DockPanelEventArgs.Panel property identifies the panel which is about to be resized. The StartSizingEventArgs.SizingSide property represents the dock panel's dragging edge. To cancel the resizing operation before it's started set the event's DockPanelCancelEventArgs.Cancel parameter to true.

Refer to the Controlling Resizing Operations document for more information.
