數據表是不是在生產服務器上載，但在當地

Question

DataTable的工作完美結合後，在生產服務器上載，但在當地和現場服務器工作完全是後不綁定：IIS 7.0

下面是C＃代碼。

protected void FillGrid(string Paravalue) 
{ 
    try 
    { 
     bo.Para1 =Request.QueryString["ApplicationStatus"].ToString();pplicationStatus 
     bo.Para2 = Session["Userid"].ToString();// SubmittedBy 
     bo.Para3 = Paravalue;//Paravalue 
     DataTable dt = bl.Get_Applications(bo); 
     GridView1.DataSource = dt; 
     GridView1.DataBind(); 

     if (dt.Rows.Count > 0) 
     { 

      lbl_texxt.Text = dt.Rows[0]["PositionTitle"].ToString(); 
     } 
     else 
     { 

      lbl_texxt.Text = "No Data"; 
     } 
     if (GridView1.Rows.Count > 0) 
     { 
      btnExport.Visible = true; 
     } 
     else 
     { 
      btnExport.Visible = false; 
     } 
    } 
    catch (Exception ex) 
    { 
    Console.WriteLine("er" + ex); 
    } 
} 

下面是Gridview代碼。

 <asp:GridView ID="GridView1" runat="server" DataKeyNames="PositionId" 
       AllowSorting="True" AlternatingRowStyle-CssClass="alt" 
       AutoGenerateColumns="False" CssClass="mGrid"

     </ItemTemplate> 
     <HeaderStyle Width="200px" HorizontalAlign="Left" VerticalAlign="Middle" />

     <ItemStyle Width="140px" HorizontalAlign="Center" VerticalAlign="Middle" Font-Bold="true" Font-Underline="true" CssClass="grid_row1_action" /> 
    </asp:TemplateField> 
    <asp:TemplateField HeaderText="PositionId" Visible="false"> 
     <ItemTemplate> 
     <asp:Label ID="lbl_ProjectID" runat="server" Text='<%# Eval("PositionId") %>'></asp:Label> 
     </ItemTemplate> 
    </asp:TemplateField> 
    </Columns>

    </EmptyDataTemplate> 
</asp:GridView> 

我將live db恢復到本地，並檢查工作正常，顯示32000個數據到本地主機的gridview中。還有一件事是它在顯示No Data之後花時間加載到活動服務器。同樣保持try catch塊並獲得'無數據'和ApplicationStatus查詢字符串值的變化，那麼該數據顯示低於10000萬條記錄。

GrivView-尋呼港島線由數據源對象被tunned並加載基於的PageIndex（按需）中的記錄，並從除去的GridView尋呼。

我看到你的問題在你的編碼中沒有錯誤。但是可能會在您用於填充數據表的類中錯誤地定義連接字符串。所以，請在同一頁面上寫下所有內容，不要在某些時間使用班級來查找錯誤。你可以使用下面的代碼。它可能會幫助你找到錯誤。

protected void FillGrid(string Paravalue) 
{ 
    try 
    { 
     bo.Para1 = Request.QueryString["ApplicationStatus"].ToString();//ApplicationStatus 
     bo.Para2 = Session["Userid"].ToString();// SubmittedBy 
     bo.Para3 = Paravalue;//Paravalue 
     //DataTable dt = bl.Get_Applications(bo); 
     SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["your connection name"].ConnectionString); 
     DataTable dt = new DataTable(); 
     SqlCommand cmd = new SqlCommand("your query or procedure name", con); 
     cmd.Parameters.AddWithValue("Para1", bo.Para1); 
     cmd.Parameters.AddWithValue("Para1", bo.Para1); 
     cmd.Parameters.AddWithValue("Para1", bo.Para1); 
     SqlDataAdapter da = new SqlDataAdapter(cmd); 
     da.Fill(dt); 
     GridView1.DataSource = dt; 
     GridView1.DataBind(); 

     if (dt.Rows.Count > 0) 
     { 

      lbl_texxt.Text = dt.Rows[0]["PositionTitle"].ToString(); 
     } 
     else 
     { 

      lbl_texxt.Text = "No Data"; 
     } 
     if (GridView1.Rows.Count > 0) 
     { 
      btnExport.Visible = true; 
     } 
     else 
     { 
      btnExport.Visible = false; 
     } 
    } 
    catch (Exception ex) 
    { 
     Console.WriteLine("er" + ex); 
    } 
}
