public event ColumnMovingEventHandler ColumnMoving

Event Data

The event handler receives an argument of type ColumnMovingEventArgs containing data related to this event. The following ColumnMovingEventArgs properties provide information specific to this event.

Property	Description
Cancel (Inherited from System.ComponentModel.CancelEventArgs)
Column (Inherited from Infragistics.Win.UltraWinListView.CancelableColumnEventArgs)	Returns the UltraListViewColumnBase with which this instance is associated.

Example

The following code sample demonstrates how the UltraListView's ColumnMoving and ColumnMoved events can be handled to conditionally prevent a column from being moved, and change the visible position of a column:

For an overview of how to handle events in Visual Basic or Visual C#, see Event Handlers in Visual Basic and Visual C#. For specific information and code examples illustrating how to consume events in your application, see Consuming Events in the .NET Framework Developer's Guide.
