Question

私はフォームのいずれかでWebアプリケーションを開発していますが、奇妙な問題があります。私は使用している私には非常に奇妙な問題です！ページのIpPostBackもpageloadイベントで、助けてください私は.....ここ

 protected void grdmanageloans_RowCommand(object sender, GridViewCommandEventArgs e) 
    { 
     if (e.CommandName == "Info") 
     { 
      try 
     { 
      int loanid = Convert.ToInt32(e.CommandArgument); 
      Session["Loanid"] = loanid; 
      Session["Edit"] = "Edit"; 
      TabContainer1.ActiveTabIndex = 1; 
      Session["TabContainer1"] ="loantab"; 
      Session["Tabloan"] = "Tabloan"; 
      Response.Redirect("Mortgageclient.aspx"); 

     } 
     catch { } 
        } 
     if (e.CommandName == "Delete") 
     { 
      try 
      { 

       int LoanId = Convert.ToInt32(e.CommandArgument); 

       var PmtScheduleHistory = from del in mortgageentity.Pmt_Schedule_History where del.Loan.Loan_ID == LoanId select del; 
       var LoanPayment = from del in mortgageentity.Payments where del.Loan_ID == LoanId select del; 

       if (PmtScheduleHistory.Count() > 0) 
       { 
        var DelPmtScheduleHistory = (from del in mortgageentity.Pmt_Schedule_History where del.Loan.Loan_ID == LoanId select del).First(); 
        mortgageentity.DeleteObject(DelPmtScheduleHistory); 
        mortgageentity.SaveChanges(); 
       } 
       var Getpayments = from db in mortgageentity.Payments where db.Loan_ID == LoanId select db; 
       if (Getpayments.Count() > 0) 
       { 
        foreach (var i in Getpayments) 
        { 
         mortgageentity.DeleteObject(i); 
         mortgageentity.SaveChanges(); 
        } 
       } 

       if (LoanPayment.Count() > 0) 
       { 
        var DelPmtScheduleHistory = (from del in mortgageentity.Payments where del.Loan_ID == LoanId select del.Payment_Status.PaymentStatus_ID).First(); 
        mortgageentity.DeleteObject(DelPmtScheduleHistory); 
        mortgageentity.SaveChanges(); 
       } 

       var deletedata = (from del in mortgageentity.Loans where del.Loan_ID == LoanId select del).First(); 
       mortgageentity.DeleteObject(deletedata); 
       mortgageentity.SaveChanges(); 
       BindData(); 
      } 
      catch { } 
     } 

     if (e.CommandName == "AddNewloan") 
     { 
      Session["Addnewloan"] = "Addloan"; 
      Response.Redirect("Information.aspx"); 
     } 
    }

Answer 1

これを試してみてください：

<asp:LinkButton ID="lnkeinfo" runat="server" CausesValidation="false" CommandName="Info" 
                      CommandArgument='<%# Bind("Loan_ID") %>'>Information</asp:LinkButton> 

Answer 2

セッションでこれらのパラメータを保存しないようにRESTfulアーキテクチャを使用し、密接に結合されたページを作るのはなぜですか？ 情報という名前のリンクを、ボタンの代わりに（データをポストバックする）グリッドに作成し、それらの末尾にクエリ文字列と追加します。これはより良いアプローチであり、結果は同じです。
