我有一个信用卡对象的列表。信用卡类如下:绑定列表GridView
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace Client
{
public class CreditCard
{
public String A_Number;
public String A_Name;
public String A_Type;
public String A_Owner_Type;
public String Bank_City;
public String Bank_State;
public String Bank_ZIP;
public String Balance;
public String C_Username;
public CreditCard()
{
}
}
}
在另一类,我想列表绑定到网格视图如下:
protected void Page_Load(object sender, EventArgs e)
{
List<CreditCard> list = (List<CreditCard>)Session["list"];
GridView_List.DataSource = list;
GridView_List.DataBind();
}
不过,我收到以下错误:
The data source for GridView with id 'GridView_List' did not have any properties or attributes from which to generate columns. Ensure that your data source has content.
什么问题?我检查了列表中实际包含数据,所以我不知道它为什么不起作用?这个问题怎么解决?
您可以发布GridView_List控件的ASPX内容吗?看起来像GridView试图访问您的CreditCard对象中不存在的列。 –
