一個RDLC

Question

我寫這個代碼的動態填充：

namespace ImportarAlamo 
{ 
    public partial class RelIndi : Form 
    { 
     public RelIndi() 
     { 
      InitializeComponent(); 
     } 

     private void RelIndi_Load(object sender, EventArgs e) 
     { 
      reportViewer1.Visible = false; 
     } 

    private void button1_Click(object sender, EventArgs e) 
    { 
     reportViewer1.Visible = true; 
     reportViewer1.Reset(); 
     fillrel(); 

     // Here is the part to populate the report : 
     ReportDataSource DS = new ReportDataSource("individual2",fillrel()); 
     reportViewer1.LocalReport.DataSources.Clear(); 
     reportViewer1.LocalReport.ReportPath = @"C:\relatorios\Report8.rdlc"; 
     reportViewer1.LocalReport.DataSources.Add(DS); 
     reportViewer1.LocalReport.Refresh(); 

    } 

    public DataSet fillrel() 
    { 
     DataSet uny = new DataSet(); 

     SqlConnection abre = Tconex.GetConnection(); 
     SqlDataAdapter da2 = new SqlDataAdapter(); 
     SqlCommand llena = new SqlCommand("rel_Noparam", abre); 
     llena.CommandType = CommandType.StoredProcedure; 
     da2.SelectCommand = llena; 
     da2.Fill(uny,"rel"); 
     abre.Close(); 
     return uny; 
    } 

的report8.rdlc什麼都沒有，現在的代碼有沒有錯誤，但我可以把一個表矩陣上的報告，我怎麼顯示的字段???

你忘了數據源添加到集合：

ReportDataSource DS = new ReportDataSource("individual2",fillrel()); 
reportViewer1.LocalReport.DataSources.Clear(); 
reportViewer1.LocalReport.DataSources.Add(DS);
