Question

好的，我真的对这个人感到愚蠢....

我有这堂课：

Public Class whatever
Public id as string
Public name as string
public date as string
end class

我使用此代码：

dim personlist as new arraylist

dim person as new whatever
person.id="1"
person.name="bozo"
person.date="6-6-6"
personlist.add(person)

然后我再说一遍，这样我就可以用我想要在gridview中显示的所有信息填充我的arraylist。

问题在于：

gridview1.datasource = personlist
gridview1.databind()

执行时，我收到错误消息：

The data source for GridView with id 'gdpersonlist' did not have any properties or attributes from which to generate columns.  Ensure that your data source has content.

任何人都可以帮助我，或者让我指出正确的方向吗？！

Answer 1

尝试使用属性而不是字段。网格视图的数据绑定不适用于字段。

Public Class whatever
  Public _id as string
  Public name as string
  public date as string

  Public Property Id As String 
    Get 
      Return _id
    End Get
    Set (value as String )
      _id = value
    End Set
  End Property

  ' repeat for all 3 fields
end class

将arraylist绑定到网格视图（部分无论......）
