vb.net - 对 Gridview 进行排序时找不到列

Question

我需要帮助对 gridview 进行排序，下面是我的代码：

Protected Sub TaskGridView_Sorting(ByVal sender As Object, ByVal e As GridViewSortEventArgs) Handles GridView1.Sorting

    'Retrieve the table from the session object.
    Dim dt As DataView = dsData.AsDataView


    If dt IsNot Nothing Then

        'Sort the data.
        If (GridView1.SortDirection() = SortDirection.Ascending) Then
            dt.Sort = e.SortExpression & " " & SortDirection.Descending
        Else
            dt.Sort = e.SortExpression & " " & SortDirection.Descending
        End If

        GridView1.DataSource = dt
        GridView1.DataBind()

    End If

我目前得到：找不到列[我正在排序的任何列]

我是 VB 的新手，正在努力学习这一点，我无法使任何其他示例代码工作。

感谢您的帮助。

补充：其他代码：

在页面加载时我运行我的存储过程，然后它绑定数据：

    Dim objConn As IDbConnection = Nothing
    Dim strBlder As New System.Text.StringBuilder
    Dim providerID As String = Request.QueryString("ProviderID")
    Dim providerName As String = Request.QueryString("ProviderName")
    GridView1.PagerSettings.Mode = PagerButtons.NumericFirstLast

存储过程查询：

    GridView1.DataSource = dsData
    GridView1.AllowSorting = True
    GridView1.DataBind()

ASPX 代码：

    <asp:GridView ID="GridView1" runat="server" style="margin-right: 0px" 
        AllowPaging = "True" PageSize = "50" AllowSorting = "true">
        <Columns>
            <asp:CommandField ShowEditButton="True" />
            <asp:TemplateField HeaderText="Status"></asp:TemplateField>
        </Columns>
    </asp:GridView>

代替

If (GridView1.SortDirection() = SortDirection.Ascending) Then
    dt.Sort = e.SortExpression & " " & SortDirection.Descending
Else
    dt.Sort = e.SortExpression & " " & SortDirection.Descending
End If

和

If (GridView1.SortDirection() = SortDirection.Ascending) Then
    dt.Sort = e.SortExpression & " ASC"
Else
    dt.Sort = e.SortExpression & " DESC"
End If
