我搜索了高和低如何实现这一点在我的网页上。我有一个顶级的gridview,它允许排序和嵌套的网格视图,当页面编译'x'嵌套的网格视图时,动态生成的动态html div可以在用户命令中从不可见变为可见。我遇到的问题是,我无法弄清楚如何在不折叠div的情况下对这些嵌套的gridviews进行排序/导致回发。添加排序到一个嵌套的Gridview ASP.net与C#
下面示出了如何在主gridview的(gvSalesDiv)和嵌套的GridView(gvTheDivisionCustomers)在asp.net生成
<asp:GridView ID="gvSalesDiv" AllowSorting="true" onsorting="GridView1_Sorting" runat="server" GridLines="Both" OnRowDataBound="gvOrderLineDetail_RowDataBound" AutoGenerateColumns="False"

HeaderStyle-Font-Size="Medium" Visible="true">
<Columns>
<asp:TemplateField HeaderText="Toggle Detail">
<ItemTemplate>
<a href="javascript:switchViews('div<%# Eval("SalesDivision") %>');">
<img id="imgdiv<%# Eval("SalesDivision") %>" alt="toggle" border="0"
src="/salesconsole/toggle-off.png" />
</a>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="SalesDivision" HeaderText="Sales Division">
<ItemStyle Font-Bold="True" ForeColor="CornflowerBlue" HorizontalAlign="Center"></ItemStyle>
</asp:BoundField>
<asp:BoundField DataField="LastDay" SortExpression="LastDay" DataFormatString="{0:C}" HeaderText="Last 24 Hours" >
</asp:BoundField>
<asp:BoundField DataField="LastWeek" SortExpression="LastWeek" DataFormatString="{0:C}" HeaderText="Last 7 Days" >

<asp:BoundField DataField="CustomerID" HeaderText="ID"/>

我填充上的Page_Load主GridView和使用OnRowDataBound方法创建嵌套GridView的。我有一个主gridview的排序方法,它也能正常工作。下面是嵌套GridView中OnSorting方法,这是我在哪里卡住了...我不能访问该对象
protected void GridView2_Sorting(Object sender, GridViewSortEventArgs e)
{
// TO DO : Sort the nested gridview....All I can get at is the sort expressions or
cast the sender into a gridview but even then I wouldn't know the correct SQL query to bind with unless I knew which 'div' I was in...
}
谢谢你,我可以看到这将如何工作,接下来的问题是,这会导致页面状态丢失,即。当我点击排序内部网格视图时,Div会崩溃,因为外部网格视图是'重新绑定'。你有什么想法,我怎么能保持divs的状态? – AndyBryce 2013-03-05 12:30:04
也许你可以尝试使用Ajax UpdatePanel控件来强制gridview在没有完整页面回发的情况下重新加载。 – Cerbi 2013-03-05 12:41:40
