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.

Gets or sets whether to cancel the drag operation.  
Gets the number of columns or rows to move.  
Gets the column or row index of the drag.  
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.  
Gets the view in which the columns or row are being dragged.  

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.

This example does not allow the first four columns to be moved.
fpSpread1.AllowColumnMove = true;

fpSpread1.ColumnDragMove +=new FarPoint.Win.Spread.DragMoveEventHandler(fpSpread1ColumnDragMove);

private void fpSpread1ColumnDragMove(object sender, FarPoint.Win.Spread.DragMoveEventArgs e)
      if (e.Index < 3)
            e.Cancel = true;
FpSpread1.AllowColumnMove = True

Dim eh As FarPoint.Win.Spread.DragMoveEventHandler = AddressOf Fpspread1ColumnDragMove
AddHandler FpSpread1.ColumnDragMove, eh

Private Sub Fpspread1ColumnDragMove(ByVal sender As Object, ByVal e As FarPoint.Win.Spread.DragMoveEventArgs) Handles FpSpread1.ColumnDragMove
      If e.Index < 3 Then
            e.Cancel = True
End Sub
