  <pre><code>ReportViewer1.Reset();
  
  //Data Source
  DataTable dt = GetData();
  ReportDataSource rds = new ReportDataSource("DataSet1", dt);
  ReportViewer1.LocalReport.DataSources.Add(rds);
  
  //Path
  ReportViewer1.LocalReport.ReportPath = "Report3.rdlc";
  
  //Refresh
  ReportViewer1.LocalReport.Refresh();
  
  
  private DataTable GetData()
  {
      DataTable dt = new DataTable();
      string connStr = @"Data Source= OVI-PC\SQLEXPRESS; Database =RdlcDB; Integrated Security= true;";
      using (SqlConnection cn = new SqlConnection(connStr))
      {
          SqlCommand cmd = new SqlCommand("SELECT  CustomerID ,CompanyName,ContactName,ContactTitle,Address,City,Country,Phone FROM Customers",cn);
          cn.Open();
          SqlDataReader reader = cmd.ExecuteReader();
          dt.Load(reader);
      }
  
      return dt;
  }
