RDLC-本地報告處理期間發生錯誤。報告定義無效

Question

我有一個報告窗體「Form1ReportSale」。在它的加載事件中，我想根據來自另一個表單的ID生成RDLC報告。當我將我的程序置於調試模式時，DataSet會返回期望值，但會引發錯誤。

請查收附件

我 「Form1ReortSale」 加載事件代碼如下：

public partial class Form1ReportSale : Form 
{ 
    string CS; 
    private string id; 
    public string UserID 
    { 
     get { return id; } 
     set { id = value; } 
    } 
    public Form1ReportSale() 
    { 
     InitializeComponent(); 
     CS = ConfigurationManager.ConnectionStrings["BikeDB"].ConnectionString; 
    } 

    private void Form1ReportSale_Load(object sender, EventArgs e) 
    { 
     this.WindowState = FormWindowState.Maximized; 
     //DataSet1NewCustomerBike dsCustomers = GetData(id); 
     reportViewer1.ProcessingMode = ProcessingMode.Local; 
     reportViewer1.LocalReport.ReportPath = @"E:\Working Area\Directorate Of IT Project\Own Practices\BikeShowRoom\BikeShowRoom\Reports\Form1ReportSale.cs"; 
     DataSet ds = new DataSet(); 
     ds = getDataByID(Convert.ToInt32(id)); 
     ReportDataSource datasource = new ReportDataSource("DataSet1Customer",ds.Tables[0]); 
     this.reportViewer1.LocalReport.DataSources.Clear(); 
     reportViewer1.LocalReport.DataSources.Add(datasource); 
     reportViewer1.LocalReport.Refresh(); 
     reportViewer1.RefreshReport(); 
    } 

    private DataSet getDataByID(int ID) 
    { 
     DataSet ds = new DataSet(); 
     using (SqlConnection con = new SqlConnection(CS)) 
     { 
      SqlCommand cmd = new SqlCommand("SELECT * FROM AddNewBike WHERE ID = '"+ID+"'", con); 
      SqlDataAdapter ad = new SqlDataAdapter(cmd); 
      con.Open(); 
      ad.Fill(ds); 
     } 
     return ds; 
    } 
}

檢查出你給的路徑：

reportViewer1.LocalReport.ReportPath = @"E:\Working Area\Directorate Of IT Project\Own Practices\BikeShowRoom\BikeShowRoom\Reports\Form1ReportSale.cs"; 

Form1ReportSale報告擴展應該是.rdlc而不是.cs ...複製你給你報告的專有名稱...或者試試這個

reportViewer1.LocalReport.ReportPath = "~/Reports/Form1ReportSale.rdlc";
