NavBarControl.NavDragOver Event

Fires repeatedly when a link is being dragged and is allowed to be dropped.

Namespace:DevExpress.XtraNavBar
Assembly:DevExpress.XtraNavBar.v17.2.dll

Expanded Syntax

Expanded Event Data

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

The following NavBarDragDropEventArgs properties provide information specific to this event.
Property Description
AllowedEffect Gets which drag-and-drop operations are allowed by the originator (or source) of the drag event.
Data Gets the System.Windows.Forms.IDataObject that contains the data associated with this event.
Effect Gets or sets the target drop effect in a drag-and-drop operation.
Group Gets a group into which a dragged item is about to be or has been dropped.
InsertPosition Gets the position within the group to which the link is about to be or has been dropped.
KeyState Gets the current state of the SHIFT, CTRL, and ALT keys, as well as the state of the mouse buttons.
X Gets the x-coordinate of the mouse pointer, in screen coordinates.
Y Gets the y-coordinate of the mouse pointer, in screen coordinates.

Expanded Remarks

The NavBarControl allows end-users to perform link drag and drop operations. Write a NavDragOver event handler to perform repeated actions when a link is being dragged and it is allowed to be dropped.

Use the DragDropFlags and NavBarGroup.DragDropFlags properties to control the component's behavior in relation to link drag and drop operations.

Expanded Example

The sample code below represents a NavDragOver event handler. The event handler prohibits dropping to all but the last item in the group. The target group is identified via the NavBarDragDropEventArgs.Group property of the event's parameter. The dropping position is obtained via the NavBarDragDropEventArgs.InsertPosition property.
