例如：绑定使用JQuery返回数据表到的GridView的方法
public DataTable GetCountries()
{
//all sql connection
//fetching data into a datatable
return objDataTable // returns a datatable
}
public void BindGridView()
{
GridView1.DataSource = GetCountries();
GridView1.DataBind();
}
，我可以上面的代码实现的事情是结合一个GridView， 但我想GridView1使用JQuery和数据表来绑定由GetCountries（）方法返回...
请任何人都可以给我一个最简单的例子...？
