無法在使用VB.NET中的DataSet的GridView中進行排序

我試圖對GridView進行排序，該列中有6列是DataSet的數據綁定。所有這些數據都是通過stored procedure調用的。我已經瀏覽了interweb上不同的帖子和教程，並最終得到了我認爲對我的頁面最好的一個。但是這一個，我不斷收到一個錯誤，無法在使用VB.NET中的DataSet的GridView中進行排序

異常類型：System.IndexOutOfRangeException
消息：找不到列LoanOfficer

我願意幫助這個方法，甚至建議一種處理排序的不同方法。這裏是我的代碼：
ASPX

<asp:GridView ID="dgvBranchChange" runat="server" AutoGenerateColumns="False" AllowPaging="True"

代碼隱藏

Protected Sub dgvBranchChange_Sorting(sender As Object, e As GridViewSortEventArgs) 

    'Retrieve the current table 
    Dim dsBranchChange As DataSet 
    Dim asParams(0) As IDbDataParameter 
    Dim lDB As New RHubCoreFunctions.RHubDB 
    asParams(0) = lDB.dpCreateDataParameter("@AccountID", DbType.String, 8, AccountSelected.AccountID) 
    dsBranchChange = lDB.GetDataSet("ssp_Account_LO_Branch_Change", asParams) 

    Dim dt As DataView = dsBranchChange.Tables(0).AsDataView 

    If dt IsNot Nothing Then 

     'sort the data 
     If (dgvBranchChange.SortDirection() = SortDirection.Ascending) Then 
      dt.Sort = e.SortExpression & " ASC" 
     Else 
      dt.Sort = e.SortExpression & " DESC" 
     End If 

     dgvBranchChange.DataSource = dt 
     dgvBranchChange.DataBind() 
    End If 

End Sub

編輯： 我發現我用錯了的SortExpression。我使用的是與標題文本相同的文本，就像所有演練/教程中給出的那樣。但它必須與從表中獲取數據的列名相同，即SQL表。

但現在我只能按升序的第一列，僅此而已
