嵌套Grid，光棍月大放送，不藏着掖着。实在写的不好，没脸藏啊~只考虑显示排序修改什么的都不管！
<f:TemplateField ColumnID="griditem" Hidden="true" RenderAsRowExpander="true">
<ItemTemplate>
<div runat="server" id="divItem" class="expander">
</div>
</ItemTemplate>
</f:TemplateField>
F(‘<% =Grid1.ClientID%>‘).view.on(‘expandBody‘, function (rowNode, record, expandRow, eOpts) {
//传到后台，参数为行ID，行绑定的数据ID
F.customEvent(‘GridItem_‘ + rowNode.id + ‘_‘ + record.get(‘ItemId‘));
});
<f:Panel runat="server" ID="PanelGrid1" Height="0px" Hidden="false">
<Items>

<f:TemplateField Width="60px" HeaderText="序号">
<ItemTemplate>
<asp:Label runat="server" Text=‘<%# Container.DataItemIndex + 1 %>‘></asp:Label>
