Question

我已完成Microsoft关于使用SQL Server Reporting Services（SSRS）创建Web App的简短课程（create-drillthrough-rdlc-report-with-parameters-reportviewer）

在课程中，我创建了报告，允许钻取操作并链接另一个报告（使用另一个数据集）。这项工作很好但是为了我的目的，我需要更多地控制这个过程，这就是我创建按钮来执行相同操作的原因。按钮用于从DB检索新值并在当前ReportViewer中显示结果第一个按钮正在执行同一报告（ Report1 ）和数据集（ DataSet1 ）的数据检索像父母报告。第二个是检索另一个报告（ Report2 ）和数据集（ DataSet2 ）的数据。

代码几乎相同，在教程的标准钻取操作期间执行，但是点击第二个按钮（ toReport2 ）没有显示任何重新连接。我不知道这里有什么问题。我检查了数据表结果 - 存在并匹配数据集。浏览WEB中的类似帖子并不是很有帮助。请帮我解决这个问题。

protected void DataSet1Button_Click(object sender, EventArgs e)
{
    this.ReportViewer1.Reset();
    this.ReportViewer1.ProcessingMode = ProcessingMode.Local;
    this.ReportViewer1.LocalReport.DataSources.Clear();

    DataTable dt1 = getDataSet1Data();
    ReportDataSource datasource = new ReportDataSource("DataSet1", dt1);
    this.ReportViewer1.LocalReport.DataSources.Add(datasource);
    this.ReportViewer1.LocalReport.ReportPath = (@"...mypath...\MyApp7\Report1.rdlc");

    this.ReportViewer1.LocalReport.Refresh();
    this.ReportViewer1.Visible = true;

}

protected void DataSet2Button_Click(object sender, EventArgs e)
{
    this.ReportViewer1.Reset();
    this.ReportViewer1.ProcessingMode = ProcessingMode.Local;
    this.ReportViewer1.LocalReport.DataSources.Clear();

    DataTable dt2 = getDataSet2Data();
    ReportDataSource datasource2 = new ReportDataSource("DataSet2", dt2);
    this.ReportViewer1.LocalReport.DataSources.Add(datasource2);
    this.ReportViewer1.LocalReport.ReportPath = (@"...mypath...\MyApp7\Report2.rdlc");

    this.ReportViewer1.LocalReport.Refresh();
    this.ReportViewer1.Visible = true;

}

public DataTable getDataSet1Data()
{
    string constring = "Data Source = x.x.x.x; Initial Catalog = Adventureworks2014; Integrated Security = SSPI";
    using (SqlConnection sqlconn = new SqlConnection(constring))
    {
        string commandText = "SELECT ProductID, Name, ProductNumber, MakeFlag, FinishedGoodsFlag, Color, SafetyStockLevel, ReorderPoint, StandardCost, ListPrice, Size, SizeUnitMeasureCode, WeightUnitMeasureCode, Weight, DaysToManufacture, ProductLine, Class, Style, ProductSubcategoryID, ProductModelID, SellStartDate, SellEndDate, DiscontinuedDate, rowguid, ModifiedDate FROM Production.Product";
        using (SqlCommand sqlcomm = new SqlCommand(commandText, sqlconn))
        {
            using (SqlDataAdapter sqladap = new SqlDataAdapter(sqlcomm))
            {
                using (DataSet1 dset1 = new DataSet1())
                {
                    sqladap.Fill(dset1, dset1.Product.TableName);
                    return dset1.Product;
                }
            }
        }
    }
}
public DataTable getDataSet2Data()
{
    string constring = "Data Source = x.x.x.x; Initial Catalog = Adventureworks2014; Integrated Security = SSPI";
    using (SqlConnection sqlconn = new SqlConnection(constring))
    {
        string commandText = "SELECT PurchaseOrderID, PurchaseOrderDetailID, OrderQty, ProductID, ReceivedQty, RejectedQty, StockedQty FROM Purchasing.PurchaseOrderDetail";
        using (SqlCommand sqlcomm = new SqlCommand(commandText, sqlconn))
        {
            using (SqlDataAdapter sqladap = new SqlDataAdapter(sqlcomm))
            {
                using (DataSet2 dset2 = new DataSet2())
                {
                    sqladap.Fill(dset2, dset2.PurchaseOrderDetail.TableName);
                    return dset2.PurchaseOrderDetail;
                }
            }
        }
    }

DataSet1Button_Click的结果

DataSet2Button_Click的结果

好的，解决了！来自https://stackoverflow.com/users/2400834/tezzo的评论很有帮助。代码很好。问题出在Report2设置中，根据该设置，预计会增加钻取参数。我删除了它，现在正在工作。问题似乎很愚蠢，但我认为，微软应该针对此类情况实施一些通知。

bugfix

SSRS，点击按钮
