    Hello Damon,

    Thank you for writing. 

    You can find below a sample code snippet demonstrating how to access the start/end date of the dragged task element:
    this.radGanttView1.GanttViewElement.DragDropService.PreviewDragStart += DragDropService_PreviewDragStart;
    private void DragDropService_PreviewDragStart(object sender, Telerik.WinControls.PreviewDragStartEventArgs e)
        GanttViewTaskElement taskElement = e.DragInstance as GanttViewTaskElement;
        if (taskElement != null)
            e.CanStart = true;
            GanttViewDataItem item = ((GanttViewTaskItemElement)taskElement.Parent).Data;
            Console.WriteLine("Start: " + item.Start + " End: " + item.End);

    I hope this information helps. Should you have further questions I would be glad to help.
