在实际项目开发中，我找到了一种利用GridView实现分级效果的方法，最终效果图如下：
以下是实现代码：
Aspx页面
复制代码 代码如下:
<asp:GridView SkinID="GridView" runat="server" AutoGenerateColumns="false"
Width="100%" AllowPaging="true" PageSize="10">
<Columns>
<asp:TemplateField HeaderStyle-Width="1%">
<ItemTemplate>
<asp:Image runat="server" ImageUrl="~/images/dn.gif" />
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" />
</asp:TemplateField>
<asp:BoundField DataField="CustomerID" HeaderText="客户编号" HeaderStyle-Width="10%">
<ItemStyle HorizontalAlign="Center" />
</asp:BoundField>
<asp:BoundField DataField="CompanyName" HeaderText="公司名称" HeaderStyle-Width="10%">
<ItemStyle HorizontalAlign="Center" />
</asp:BoundField>
<asp:BoundField DataField="ContactName" HeaderText="联系人" HeaderStyle-Width="10%">
<ItemStyle HorizontalAlign="Center" />
</asp:BoundField>
