重複插入ASP.NET

這讓我在上週瘋狂。我已經閱讀了許多有關這個問題的問題和答案，但仍然無法解決我的問題。我已經檢查了所有可能的事件觸發，並找不到任何。重複插入ASP.NET

我kondisi.aspx：

<!-- some header here --> 

       <form id="form1" runat="server" class="form-horizontal"> 
        <div class="box-body"> 
         <div class="form-group"> 
          <label class="col-sm-2 control-label text-right">Kondisi :</label> 
          <div class="col-sm-10"> 
           <asp:textbox id="tbkondisi" runat="server" cssclass="form-control" textmode="MultiLine"></asp:textbox> 
          </div> 
         </div> 

         <asp:label id="lInfo" runat="server" cssclass="error" visible="False"></asp:label> 
         <asp:label id="linfoberhasil" runat="server" cssclass="berhasil" visible="False"></asp:label> 

         <div class="box-footer text-center"> 
          <dxe:aspxbutton id="btSimpan" runat="server" text="Simpan" cssclass="btn btn-primary" enabledefaultappearance="False"></dxe:aspxbutton> 
          <dxe:aspxbutton id="btBatal" runat="server" text="Reset" cssclass="btn btn-danger" enabledefaultappearance="False"></dxe:aspxbutton> 
         </div> 

         <asp:hiddenfield id="hfID" runat="server" /> 
         <asp:hiddenfield id="hfMode" runat="server" /> 

<!-- some grid and footer here -->

btSimpan點擊事件，處理的按鈕：

Protected Sub btSimpan_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btSimpan.Click 
    Try 
     If Validasi() Then 
      If hfMode.Value = "Insert" Then 
       Insert() 
       linfoberhasil.Visible = True 
       linfoberhasil.Text = "Simpan Berhasil" 
      Else 
       Update(hfID.Value) 
       linfoberhasil.Visible = True 
       linfoberhasil.Text = "Update Berhasil" 
      End If 
     End If 
    Catch ex As Exception 
     Response.Write("<b>Error button simpan :</b>" & ex.ToString) 
    End Try 
End Sub

這是檢查重複的項目驗證函數：

Private Function Validasi() As Boolean 
    Try 
     clear_label() 
     If hfMode.Value = "Insert" Then 
      If tbkondisi.Text.Trim = "" Then 
       lInfo.Visible = True 
       lInfo.Text = "Nama kondisi masih kosong" 
       Return False 
      End If 

      sqlstring = "SELECT ID FROM KondisiPengiriman " & _ 
         "WHERE Nama_Kondisi = '" & tbkondisi.Text.Replace("'", "''") & "' " & _ 
         "AND [status] = 1 " 
      result = SQLExecuteScalar(sqlstring) 

      If result <> "" Then 
       lInfo.Visible = True 
       lInfo.Text = "Nama kondisi sudah ada" 
       Return False 
      End If 

     End If 

     If hfMode.Value = "Update" Then 
      If tbkondisi.Text.Trim = "" Then 
       lInfo.Visible = True 
       lInfo.Text = "Nama kondisi masih kosong" 
       Return False 
      End If 
     End If 


     Return True 
    Catch ex As Exception 
     Throw New Exception("Error function Validasi : " & ex.ToString) 
    End Try 
End Function

而且這裏clear_label（）函數重置所有領域：

Private Sub clear_label() 
    lInfo.Visible = False 
    lInfo.Text = "" 
    linfoberhasil.Visible = False 
    linfoberhasil.Text = "" 
End Sub

最後插入（）函數：

Private Sub Insert() 
    Try 
     sqlstring = "INSERT INTO KondisiPengiriman " & _ 
        "(Nama_Kondisi, UserName, [status]) VALUES " & _ 
        "('" & tbkondisi.Text.Replace("'", "''") & "', '" & Session("UserId") & "', 1)" 
     hasil = SQLExecuteNonQuery(sqlstring) 

     If hasil > 0 Then 
      load_grid_kondisi() 
      clear() 
     End If 

    Catch ex As Exception 
     Throw New Exception("<b>Error function insert :</b> " & ex.ToString) 
    End Try 
End Sub

似乎驗證（）剛剛接觸一個時間，它插入2倍，這是同時插入了SQL跟蹤：

我想不出什麼原因引起的這一點，似乎函數只是運行1次，但插入指令的2倍。幫助和指導來解決這個真正appreaciated。非常感謝你。

在visual studio中附加調試器，設置斷點，查看調用堆棧以查看導致雙觸發的原因。 – Steve

在另一個說明中，使用'SqlParameters' .... – Codexer

@steve：它說'這是不是有效的斷點位置'，當我嘗試在insert（）函數中設置時，但我已經試過在insert給我重複的插入。 –

對不起，我以爲SQLExecuteNonQuery(sqlstring)是內置命令。顯然這是自定義功能，它檢查了備份服務器的兩個實例名稱。並在設置中，這2個實例名稱指向同一個服務器，它是什麼使雙重插入。

現在通過刪除一個實例名來完成。謝謝。
