Question

我有一个简单的CrystalReports defigned。屏幕截图：

我在Form Load

中填充DataSet

    protected override void OnLoad(EventArgs e)
    {
        CrystalReport2 report = new CrystalReport2();

        DataSet data = GetData();

        report.SummaryInfo.ReportTitle = "My Company Billing Report";

        report.SetDataSource(data);

        DateTime startTime = new DateTime(2015, 10, 1);

        Debug.WriteLine("Start Time: " + startTime);

        DateTime endTime = startTime.AddMonths(1);

        Debug.WriteLine("End Time: " + endTime);

        report.SetParameterValue("StartTime", startTime);
        report.SetParameterValue("EndTime", endTime);

        crystalReportViewer1.ReportSource = report;

        //crystalReportViewer1.Refresh();

        base.OnLoad(e);
    }

    private static DataSet GetData()
    {
        string connectString = ConfigurationManager.ConnectionStrings["TimeSheetContext"].ConnectionString;

        SqlConnection connection = new SqlConnection {ConnectionString = connectString};

        SqlCommand sqlCmd = new SqlCommand
        {
            CommandType = CommandType.Text,
            Connection = connection,
            CommandText = "SELECT * FROM tblTimeWorked ORDER BY Link2Customer, Link2Worker, DateWorked, Location"
        };

        BillingDataSet ds = new BillingDataSet();

        SqlDataAdapter da = new SqlDataAdapter(sqlCmd);
        int blah = da.Fill(dataSet: ds, srcTable: "tblTimeWorked");
        Debug.WriteLine("# of TimeWorked Records: " + blah);

        sqlCmd.CommandText = "SELECT * FROM tblActivity";
        da = new SqlDataAdapter(sqlCmd);
        blah = da.Fill(dataSet: ds, srcTable: "tblActivity");
        Debug.WriteLine("# of Activity Records: " + blah);

        sqlCmd.CommandText = "SELECT * FROM tblCustomer";
        da = new SqlDataAdapter(sqlCmd);
        blah = da.Fill(dataSet: ds, srcTable: "tblCustomer");
        Debug.WriteLine("# of Customer Records: " + blah);

        sqlCmd.CommandText = "SELECT * FROM tblWorker";
        da = new SqlDataAdapter(sqlCmd);
        blah = da.Fill(dataSet: ds, srcTable: "tblWorker");
        Debug.WriteLine("# of Worker Records: " + blah);

        return ds;
    }

格式是我想要的，但似乎缺少一些条目。在我看来，只有第一人（工人）被选中，而其他人都没有。我是按客户分组，然后是CrystalReports中的员工。我没有对数据集进行任何过滤。我使用Sql Server Management Studio验证了记录。

记录选择是：

    {tblTimeWorked.DateWorked}  >= {?StartTime} and {tblTimeWorked.EndTime}  < {?EndTime} and {tblTimeWorked.Link2Activity} = 2

为什么CrystalReports会在群组中跳过记录？

Answer 1

我首先要尝试从Crystal Report中删除Group1和Group2，然后运行报告，以确认水晶报告确实包含了您期望的所有详细信息行。此外（也许更重要的是），在报告中包含多个数据集似乎很奇怪。只需修改您的第一个CommandText，即可包含拉动您需要的其他链接字段所需的连接（例如，客户名称，员工姓名）。这将简化事情。
