GridView+ObjectDataSource分页问题

Question

我利用GridView+ObjectDataSource设置GridView的分页显示，后台代码如下：[System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Select, true)]
        public IQueryable<FruitDroppingSurvey> GetImagoSurveyInfoByView2(int monitoringPointId, string drosophilaType, int maximumRows, int startRowIndex)
        {
            PestInfoDatabaseModelContainer Entity = new PestInfoDatabaseModelContainer();
            IQueryable<FruitDroppingSurvey> _FruitDroppingSurvey_view2 = (from c in Entity.FruitDroppingSurvey
                                                                          where c.MonitoringPointID == monitoringPointId
                                                                          where c.DrosophilaType.Equals(drosophilaType)
                                                                          orderby c.Time,c.SurveyPointID
                                                                          select c);
            return _FruitDroppingSurvey_view2;
        }        //分页计数;
        public int GetCountFruitDroppingSurvey(int monitoringPointId, string drosophilaType, int maximumRows, int startRowIndex)
        {
            IQueryable<FruitDroppingSurvey> _FruitDroppingSurvey_view2 = (from c in Entity.FruitDroppingSurvey
                                                                          where c.MonitoringPointID == monitoringPointId
                                                                          where c.DrosophilaType.Equals(drosophilaType)
                                                                          orderby c.Time, c.SurveyPointID
                                                                          select c);
            if (_FruitDroppingSurvey_view2!=null)
            {
                return _FruitDroppingSurvey_view2.Count();
            } 
            else
            {
                return 0;
            }
        }然后将GetImagoSurveyInfoByView2绑定到ObjectDataSource，
再设置ObjectDataSource的分页EnablePaging,MaximunRowsParameterName,SelectedCountMethod,StartRowIndexParameterName
再将GridView的AllowPaging设置为True.
上述各项绑定正常，但是在运行的时候，GridView能正常显示，但是数据全部显示在一页，并没有
实现分页？？？
请赐教，百分百结贴。

IQueryable<FruitDroppingSurvey> _FruitDroppingSurvey_view2 = (from c in Entity.FruitDroppingSurvey
                                                                          where c.MonitoringPointID == monitoringPointId
                                                                          where c.DrosophilaType.Equals(drosophilaType)
                                                                          where c.Time.Year==year
                                                                          where c.Time.Month==month
                                                                          orderby c.Time, c.SurveyPointID
                                                                          select c)
                                                                          .Skip(startRowIndex)
                                                                          .Take(maximumRows);
