在使用AccessDataSource時UPDATE不起作用vb asp.net

我在使用我的asp.net項目中的UPDATE命令時遇到問題。該項目允許用戶通過登錄頁面登錄，登錄頁面將用戶名和密碼與數據庫中的記錄相匹配，並將用戶名保存爲cookie。然後我有一個設置頁面，我想允許用戶編輯他們的帳戶詳細信息，但是當我使用UPDATE功能時，查詢執行時沒有任何錯誤，但不會發生更新。我正在使用一個AccessDataSource和一個UpdateCommand，希望有人可以找到我的代碼的問題，並引導我的方向正確。在此先感謝在使用AccessDataSource時UPDATE不起作用vb asp.net

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) 


    Dim sqlcmd As String 
    sqlcmd = "SELECT FirstName, SecondName, UserName, DOB, Password FROM UserTable WHERE UserName = '" & Request.Cookies("UserInfo")("userName") & "'" 
    AccessDataSource1.SelectCommand = sqlcmd 

    If (Not Page.IsPostBack) Then 

     Dim sqlcmd2 As String 
     sqlcmd2 = "UPDATE [UserTable] SET [FirstName] = ?, [SecondName] = ?, [UserName] = ?, [DOB] = ?, [Password] = ? WHERE [UserID] = ? AND ISNULL (([FirstName] = ?) OR ([FirstName] IS NULL AND ? IS NULL)) AND (([SecondName] = ?) OR ([SecondName] IS NULL AND ? IS NULL)) AND (([UserName] = ?) OR ([UserName] IS NULL AND ? IS NULL)) AND (([DOB] = ?) OR ([DOB] IS NULL AND ? IS NULL)) AND (([Password] = ?) OR ([Password] IS NULL AND ? IS NULL))" 
     AccessDataSource1.UpdateCommand = sqlcmd2 

    End If 

End Sub

      UpdateCommand = "UPDATE [UserTable] SET [FirstName] = ?, [SecondName] = ?, [UserName] = ?, [DOB] = ?, [Password] = ? WHERE [UserID] = ? AND ISNULL (([FirstName] = ?)

     </UpdateParameters> 
     </asp:AccessDataSource> 
     <asp:GridView ID="GridView1" runat="server" DataSourceID="AccessDataSource1"> 
      <Columns> 
       <asp:CommandField ShowEditButton="True" /> 
      </Columns> 
     </asp:GridView> 
<div> 
</div> 
</div> 
</form>

很抱歉，如果它是所有有點凌亂，但是這是我的第一篇文章，我不完全知道我在做什麼。
