Occurs before a column header is moved by the end user.
Syntax
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.
