您好我有DataTable绑定到Gridview。但需要将知道绑定到jqxgrid或jqxdatatable。谷歌搜索了这么多次后，我没有得到适当的解决方案。
DataTable tb1= qry.GetTicketDetails();
serviceWindow.DataSource = tb;
serviceWindow.DataBind();
这就是我现在正在做的事情。
在jquery中，我可以使用下面显示的XML。
var source =
{
dataType: "json",
dataFields: [
{ name: 'name', type: 'string' },
{ name: 'type', type: 'string' },
{ name: 'calories', type: 'int' },
{ name: 'totalfat', type: 'string' },
{ name: 'protein', type: 'string' }
],
id: 'id',
url: "data/ticket.XML", //how to take datatable from code behind file
};
答案 0 :(得分：4)

粘贴......
通过查询替换查询.....
Donot Supply Datafeild和Column Def。在.aspx页面
这是完全动态的解决方案!!!
