1.编写数据拷贝函数（封装起来，便于多处调用）；

public class GeoMapLoad
    {
        public static void CopyAndOverwriteMap(AxMapControl axMapControl, AxPageLayoutControl axPageLayoutControl)
        {
            IObjectCopy objectCopy = new ObjectCopyClass();
            object toCopyMap = axMapControl.Map;
            object copiedMap = objectCopy.Copy(toCopyMap);
            object overwriteMap = axPageLayoutControl.ActiveView.FocusMap;
            objectCopy.Overwrite(toCopyMap,ref overwriteMap);
        }
    }

2.axMapControl加载的数据发生重绘时，需要联动，所以在axMapControl的OnAfterScreenDraw事件中，需添加获取axMapControl控件中当前所显示的地理范围代码，并将当前显示范围传给axPageLayoutControl控件ActiveView对象的FocusMap中，同时调用拷贝方法；

private void axMapControl1_OnAfterScreenDraw(object sender, IMapControlEvents2_OnAfterScreenDrawEvent e)
        {
            IActiveView pAcv = axPageLayoutControl1.ActiveView.FocusMap as IActiveView;
            IDisplayTransformation displayTransformation = pAcv.ScreenDisplay.DisplayTransformation;
            displayTransformation.VisibleBounds = axMapControl1.Extent;//设置焦点地图的可视范围
            axPageLayoutControl1.ActiveView.Refresh();
            GeoMapLoad.CopyAndOverwriteMap(axMapControl1, axPageLayoutControl1);
        }

3.axMapControl加载的数据发生变化时，需要联动，所以在axMapControl的OnMapReplaced事件中需要调用数据拷贝的方法；

private void axMapControl1_OnMapReplaced(object sender, IMapControlEvents2_OnMapReplacedEvent e)
        {
            GeoMapLoad.CopyAndOverwriteMap(axMapControl1, axPageLayoutControl1);
        }

4.axMapControl中的数据显示状况发生变化时，需要联动，所以在axMapControl的OnViewRefreshed事件中需要调用数据拷贝和图层刷新的方法；

private void axMapControl1_OnViewRefreshed(object sender, IMapControlEvents2_OnViewRefreshedEvent e)
        {
            axTOCControl1.Update();
            GeoMapLoad.CopyAndOverwriteMap(axMapControl1, axPageLayoutControl1);
        }
