Occurs when AllowColumnMove is true and the user drags to move a column.

Syntax

Visual Basic (Declaration)
Public Event ColumnDragMove As DragMoveEventHandler

Visual Basic (Usage)	Copy Code
Dim instance As FpSpread Dim handler As DragMoveEventHandler AddHandler instance.ColumnDragMove, handler

C#
public event DragMoveEventHandler ColumnDragMove

Event Data

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

Property	Description
Cancel	Gets or sets whether to cancel the drag operation.
Count	Gets the number of columns or rows to move.
Index	Gets the column or row index of the drag.
MoveContent	Gets or sets whether the move operation moves the contents of the rows or columns (and rows or columns in between) without changing the index mapping.
View	Gets the view in which the columns or row are being dragged.

Remarks

This event is raised by the OnColumnDragMove method when the user drags to move a column, which can only happen when the AllowColumnMove property is true. The MoveContent property defaults to false when the control is bound; true otherwise.

For more details on the individual event arguments, refer to DragMoveEventArgs members.

Example

This example does not allow the first four columns to be moved.
