例子 ：

public DataTable GetCountries()  
{  
//all sql connection  
//fetching data into a datatable


return objDataTable // returns a datatable  
}


public void BindGridView()  
{  
GridView1.DataSource = GetCountries();  
GridView1.DataBind();  
}

我可以在上面的代码中实现的是绑定 GridView，但我想使用 JQuery 和 GetCountries() 方法返回的 DataTable 绑定 GridView1...

请任何人都可以给我一个最简单的例子......？

你也可以使用jtable。它更灵活地集成。请看这个链接：

使用WithAspNetWebFormsPage 方法

或者您也可以从 codeproject 下载源代码：
