我的CRV(Crystal Reports Viewer)中存在登录问题.

第一次打开水晶报表时，它完全可以正常运行.
但是，当我进入水晶报表的第二页时，它显示了数据库登录"对话框.

我尝试将属性EnableDatabaseLogin设置为false，但无法正常工作.

DataSet getRpt()
      {
              CrystalReport2 myRpt = new CrystalReport2();
              string myConstr = ConfigurationManager.AppSettings["ConnectionString"];
              SqlConnection myConnection = new SqlConnection(myConstr);
              SqlDataAdapter myAdapter = new SqlDataAdapter();
              DataSet3 myDataSet = new DataSet3();
              SqlCommand MyCommand = myConnection.CreateCommand();
          try
          {

              CrystalReportViewer1.DisplayGroupTree = false;
              CrystalReportViewer1.DisplayToolbar = true;

              MyCommand.CommandText = "ProcNamet";
              MyCommand.CommandType = CommandType.StoredProcedure;
              myAdapter.SelectCommand = MyCommand;

              myAdapter.SelectCommand.Parameters.Add(new SqlParameter("@myPara1",Convert.ToInt32(txtDays.Text)));
              myAdapter.SelectCommand.Parameters.Add(new SqlParameter("@myPara2", Convert.ToString(DropDownList1.SelectedValue)));
              myAdapter.SelectCommand.Parameters.Add(new SqlParameter("@myPara3", Convert.ToString(DropDownList2.SelectedValue)));

              myAdapter.Fill(myDataSet, "ProcName");
              myRpt.SetDataSource(myDataSet);
              CrystalReportViewer1.ReportSource = myRpt;
          }

          catch (Exception ex)
          {
              string strEX;
              strEX = ex.ToString();
          }
          return myDataSet;

      }

      private void Page_Init(object sender, EventArgs e)
      {
          if (!IsPostBack)
          {
              DataSet myD = getRpt();
          }
      }

      protected void Page_Load(object sender, EventArgs e)
      {
         if (!IsPostBack)
         {
             DataSet myD = getRpt();
         }
       
      }
      protected void btnPreview_Click(object sender, EventArgs e)
      {


          if (!IsPostBack)
          {
              DataSet myD = getRpt();

          }
      }

      protected void CrystalReportViewer1_Init(object sender, EventArgs e)
      {
          if (!IsPostBack)
          {
              DataSet myD = getRpt();
          }
      }

      protected void CrystalReportViewer1_Navigate(object source, CrystalDecisions.Web.NavigateEventArgs e)
      {
          if (!IsPostBack)
