Question

我有一个gridview，当我搜索一个特定的字符串时，我对我的过滤结果进行排序，但是gridview显示所有已排序，我丢失了我的过滤结果。任何想法？

ASP：

        <asp:GridView ID="GridViewWinners" runat="server" AutoGenerateColumns="False" 
            CellPadding="4" DataKeyNames="PlayerID" DataSourceID="SqlDataSource4" ForeColor="#333333" 
            GridLines="Horizontal" Width="858px" 
            onselectedindexchanged="GridViewWinners_SelectedIndexChanged" 
            AllowSorting="True" Visible="False">
            <AlternatingRowStyle BackColor="White" ForeColor="#284775" />
            <Columns>
                <asp:CommandField ShowSelectButton="True" />
                <asp:BoundField DataField="PlayerID" HeaderText="PlayerID" ReadOnly="True" 
                    SortExpression="PlayerID" Visible="False" />

gridview控件实际上不进行排序，它使用数据源控件对数据进行排序。 gridview控件将排序表达式传递给数据源控件，如果数据源控件能够这样做，则数据源控件将根据表达式进行排序。
