Question

我有一个填充了数据库中数据的GridView。我使用mssql函数获取我的数据。这就是我获取数据的方式：

private void GetNoLocationScanAddress(GridView grid, int week)
        {
            try
            {
                FunctionDataContext function = new FunctionDataContext();
                List<Fn_GetNoLocationAddressGroupedResult> address = function.Fn_GetNoLocationAddressGrouped("0X", week).ToList();
                grid.DataSource = address;
                grid.DataBind();
            }
            catch (Exception exception)
            {
                Console.WriteLine("ERROR in GetNoLocationScanAddress() method. Error Message : " + exception.Message);
            }
        }

问题是我已经在我的函数中对数据进行排序。我还使用Switch案例来确定选择哪些数据进行查看。

 protected void WeekSelector_OnIndexChanhed(object sender, EventArgs e)
        {
            switch (RadioButtonList.SelectedIndex)
            {
                case 0:
                    GetScanErrorsAddress(Grid, Convert.ToInt32(WeekSelector.SelectedValue));
                    Grid.DataBind();
                    break;

                case 1:
                    GetScanErros(Grid, Convert.ToInt32(WeekSelector.SelectedValue));
                    Grid.DataBind();
                    break;

                case 2:
                    GetNoLocationScanAddress(Grid, Convert.ToInt32(WeekSelector.SelectedValue));
                    Grid.DataBind();
                    break;

                case 3:
                    GetNoLocationScan(Grid, Convert.ToInt32(WeekSelector.SelectedValue));
                    Grid.DataBind();
                    break;
            }
        }

函数sql：

SELECT     TOP (100) PERCENT Request1.RequestID, TrackIT.dbo.Sending.Barcode, TrackIT.dbo.Address_View.AdrID, TrackIT.dbo.Address_View.Name, 
                      TrackIT.dbo.Address_View.Street, TrackIT.dbo.Address_View.HouseNo, TrackIT.dbo.Address_View.Postal, TrackIT.dbo.Address_View.City, 
                      TrackIT.dbo.Address_View.Country, Request1.Latitude +','+  Request1.Longitude AS Location,  Case when(Request1.Latitude<>'')then cast(1 as bit) else cast(0 as bit) end AS showLocation, Request1.ReceivedDate
FROM         (SELECT DISTINCT RequestID, LTRIM([Content]) AS Barcode, Latitude, Longitude, ReceivedDate
                       FROM          dbo.RequestWithLocation
                       WHERE      (Site LIKE @Site) AND ([Content] <> '') AND (AddressID = '0') AND (ReceivedDate > DATEADD(day, -@ReceivedDate, GETDATE()))) AS Request1 INNER JOIN
                      TrackIT.dbo.Sending ON Request1.Barcode = TrackIT.dbo.Sending.Barcode INNER JOIN
                      TrackIT.dbo.Address_View ON TrackIT.dbo.Sending.DeliveryAdrID = TrackIT.dbo.Address_View.AdrID

ORDER BY TrackIT.dbo.Address_View.AdrID

任何人都可以帮我吗？

Answer 1

您可以使用 - Linq（OrderBy或OrderByDescending）来对List<Fn_GetNoLocationAddressGroupedResult>进行排序。

EG。

address.OrderBy(x => x.Country);            // ascending
address.OrderByDescending(x => x.Country);  // descending

Answer 2

根据您的评论，如果用户必须能够通过按列标题对gridview进行排序，并且如果您使用的是标准ASP.NET System.Web.UI.WebControls.GridView，则只需“启用排序”即可，在属性窗格中，通过将“AllowSorting”设置为true或通过控件右上角的“弹出”选中“启用排序”。
