水晶報表未顯示使用Asp.net

我使用Asp.net 4.0和SAP Crystal報表我的問題是，我無法綁定數據集後，顯示到的ReportViewer數據。水晶報表未顯示使用Asp.net

下面是我的aspx設計師代碼

<%@ Page Title="" Language="C#" MasterPageFile="~/Site1.Master" AutoEventWireup="true" CodeBehind="productRepot.aspx.cs" Inherits="ProductionPlanning1.productRepot" %>

產品Report.aspx.cs

protected void rpt_Button1_Click(object sender, EventArgs e) 
    { 
     //DataSet2 DS2 = new DataSet2(); 
     //Fyp_1.Product pp = new Fyp_1.Product(); 
     //DS2.Tables.Add(pp.GetProduct(Convert.ToInt16(matrl_TextBox.Text)).Copy()); 
     //DS2.Tables[0].TableName = "Product"; 
     //CrystalReportProduct TR = new CrystalReportProduct(); 
     //TR.SetDataSource(DS2); 
     //product_CrystalReportViewer1.ReportSource = TR; 
     //product_CrystalReportViewer1.DataBind(); 

     GenerateReport(); 




     //DataSet ds = new DataSet(); 
     //BookTicket_Class BT = new BookTicket_Class(); 
      //ds.Tables.Add(BT.GetBookTicketReport(Convert.ToInt16(TicketNO_TextBox.Text)).Copy()); 
     //ds.Tables[0].TableName = "BookTicket"; 
     //TicketReport TR = new TicketReport(); 
     //TR.SetDataSource(ds); 
     //CrystalReportViewer1.ReportSource = TR; 
     //CrystalReportViewer1.DataBind(); 
    } 

    protected void GenerateReport() 
    { 
     SqlConnection sqlConn = new SqlConnection(@"Data Source=PROZECK- PC\R2MSSQLSERVER;Initial Catalog=FYP;Integrated Security=True"); 

     SqlCommand comd; 
     comd = new SqlCommand(); 
     comd.Connection = sqlConn; 
     comd.CommandType = CommandType.StoredProcedure; 
     comd.CommandText = "spgetproductNEW"; 



     comd.Parameters.Add("@MaterialID", SqlDbType.Int); 
     // int VAL = Convert.ToInt32(matrl_TextBox.Text); 
     if (matrl_TextBox.Text.Trim() != "") 
      comd.Parameters[0].Value = Convert.ToInt32(matrl_TextBox.Text); 
     else 
      comd.Parameters[0].Value = DBNull.Value; 




     SqlDataAdapter sqlAdapter = new SqlDataAdapter(); 
     sqlAdapter.SelectCommand = comd; 

     DataSet2 DS2 = new DataSet2(); 
     sqlAdapter.Fill(DS2, "Product"); 

     //oRpt.SetDataSource(ds); 

     //CrystalReportViewer1.Visible = true; 

     //CrystalReportViewer1.ReportSource = oRpt; 
     CrystalReportProduct TR = new CrystalReportProduct(); 
     TR.SetDataSource(DS2); 
     product_CrystalReportViewer1.ReportSource = TR; 
     // product_CrystalReportViewer1.DataBind(); 




    } 
}

下面是問題的截圖向你描述。

但是當我檢查在水晶報表設計器中的數據顯示它的數據 enter image description here

我綁定的數據第一個代碼是這樣的話，我改變了它在上面的代碼，我貼

 DataSet2 DS2 = new DataSet2(); 
     Fyp_1.Product pp = new Fyp_1.Product(); 
     DS2.Tables.Add(pp.GetProduct(Convert.ToInt16(matrl_TextBox.Text)).Copy()); 
     DS2.Tables[0].TableName = "Product"; 
     CrystalReportProduct TR = new CrystalReportProduct(); 
     TR.SetDataSource(DS2); 
     product_CrystalReportViewer1.ReportSource = TR; 
     product_CrystalReportViewer1.DataBind();

我覺得你只是錯過了最後調用; product_CrystalReportViewer1.Refresh();

你需要刪除參考crystalReport.web DLL，然後添加最新版本的crystalReport.web DLL然後它工作正常。
