SSRS，单击按钮后在ReportViewer中更改报表

Question

I have finished the short course from Microsoft about creating Web App with reports from SQL Server Reporting Services (SSRS) (create-drillthrough-rdlc-report-with-parameters-reportviewer)

During the course, i have created report, that allows drillthrough operation and links another Report (with another Dataset). That work's fine but for my purposes I need more control about the process, that's why I have created buttons to perform the same operation. Buttons are for retrieving new values from DB and showing results in current ReportViewer First button is performing data retrieving for the same report ( Report1 ) and dataset ( DataSet1 ) like parent report. Second one is retrieving data for another report ( Report2 ) and dataset ( DataSet2 ).

Code is almost the same, which was executed during standard drillthrough operation from tutorial, but hitting second button ( toReport2 ) does not showing any reuslts. I don't know what is wrong here. I have checked the datatables results - the are existing and match the datasets. Going through of similar posts in WEB was not really helpfull. Please help me to resolve this.

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;
                }
            }
        }
    }

Alright, solved! Comment from https://stackoverflow.com/users/2400834/tezzo was helpfull. Code is fine. The problem was in Report2 settings, according which, addtional drillthrough parameter was expected. I have delete it and its working now. Problem seems to be silly but i my opinion, Microsoft should implement some notification for such cases.
