protected override bool OnMouseMove(MouseEventArgs eventArgs)
{
    //Allow other components to process this event by not returning true.
    if (mouseDown)
    {
        workflowView.ScrollPosition = new Point(eventArgs.X, eventArgs.Y);
    }
    return false;
}

Protected Overrides Function OnMouseMove(ByVal eventArgs As System.Windows.Forms.MouseEventArgs) As Boolean
    ' Allow other components to process this event by not returning true.
    If mouseDown Then
        workflowView.ScrollPosition = New Point(eventArgs.X, eventArgs.Y)
    End If
    Return False
