Question

我想在asp.net中从gridview创建一个数据表。这就是我到目前为止所拥有的。我想使用jquery datatables插件创建一个可以过滤和排序的表。有没有办法从gridview，使用sql数据源执行此操作，或者还有其他我需要做的事情，比如创建一个html。唯一的问题是我需要能够更新表或动态。

您需要首先将页面元素放在正确的位置，然后尝试链接Javascript文件并在正文中调用jQuery函数，这需要在head部分中完成：

<head>
    <script src="DataTables-1.9.4/DataTables-1.9.4/media/js/jquery.js"></script>
    <script src="DataTables-1.9.4/DataTables-1.9.4/media/js/jquery.dataTables.min.js"></script>
    <script>
        $(document).ready(function () {
            $('#GridView1').dataTable();
        });
    </script>
</head>

另请注意，您必须使用GridView的ID初始化DataTable。搜索将自动启用，要启用过滤，您必须使用TemplateFields代替BoundFields，请参阅http://www.dreamincode.net/forums/topic/222381-insert-data-using-gridview-footerrow/以获取如何转换它们的示例。最后，在Code Behind中，您需要强制GridView生成正确的<thead>，<tbody>和<tfoot>部分：

    gvPortfolio.UseAccessibleHeader = true;
    gvPortfolio.HeaderRow.TableSection = TableRowSection.TableHeader;
    gvPortfolio.FooterRow.TableSection = TableRowSection.TableFooter;

只需添加<FooterStyle CssClass="FilterCell" />（或某些此类内容）即可为每个页脚单元格添加一个类，然后使用该类连接您的过滤：

$("tbody td.FilterCell").each(function (i) {
    this.innerHTML = fnCreateSelect(oTable.fnGetColumnData(i));
    $('select', this).change(function () {
        oTable.fnFilter($(this).val(), i);
    });
});

您可以在http://datatables.net/release-datatables/examples/api/multi_filter_select.html找到此示例的其余部分。请注意，如上所示，您正在查找GridView生成的<td>元素，而不是示例所期望的<th>元素。

有没有办法在asp.net中从gridview创建数据表？
