如何指定Gridview選中某一列中等于特定值的行

例如：需要Gridview選中“欄目名稱”為“辦事指南”的那行，注意DataKeyNames中必須有“欄目名稱”，否則将會出現錯誤！！不知道誰還有更好的方法解決這個問題，小女子在此熱盼高手指教：

        <asp:GridView ID="GridView1" runat="server" DataSourceID="ObjectDataSource1" DataKeyNames="欄目編号,欄目名稱" BackColor="White" BorderColor="White" BorderStyle="Ridge" BorderWidth="2px" CellPadding="3" CellSpacing="1" GridLines="None">

            <Columns>

                <asp:CommandField ShowDeleteButton="True" ShowSelectButton="True" />

            </Columns>

            <FooterStyle BackColor="#C6C3C6" ForeColor="Black" />

            <RowStyle BackColor="#DEDFDE" ForeColor="Black" />

            <SelectedRowStyle BackColor="#9471DE" Font-Bold="True" ForeColor="White" />

            <PagerStyle BackColor="#C6C3C6" ForeColor="Black" HorizontalAlign="Right" />

            <HeaderStyle BackColor="#4A3C8C" Font-Bold="True" ForeColor="#E7E7FF" />

        </asp:GridView> 

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

        Dim Row As GridViewRow

        For Each Row In GridView1.Rows

            'Dim KeyValue As String = GridView1.DataKeys(Row.RowIndex).Value  取得“欄目編号”列的值,Value也可以寫成Values(0) ,Values的索引是與Gridview中的DataKeyNames相對應的

            Dim KeyValue As String = GridView1.DataKeys(Row.RowIndex).Values(1)  '取得“欄目名稱”列的值

            If (KeyValue = "辦事指南") Then

                GridView1.SelectedIndex = Row.RowIndex

            End If

        Next

    End Sub
