我目前面臨的一個問題，而試圖填充我的網格， 其數據源基本上是一個Object Data Source這樣必須實現IConvertible：錯誤：對象，而試圖填充radgrid控件

我得到這個錯誤，我不明白爲什麼？ 有誰知道這可能來自哪裏？
編輯：這是我選擇我的數據的地方：
public static List<Agir> GetNewAgirsByClient(int idContact)
{
DataClassesActilogDataContext db = ContextSingleton.GetDataContext();
List<Agir> ListeAgir;
var v = from i in db.Agir
where (i.Agir_Contact.Any(a => a.idContact == idContact)
|| i.Projet.Projet_Contact.Any(a => a.idContact == idContact))
&& (i.idEtatIncident == 1 || i.idEtatIncident == 11) && i.Accord == null
select i;
ListeAgir = v.ToList();
return ListeAgir;
}
這裏是跟蹤：

你已經在各自的數據類型所有的人，似乎是一個不匹配呢？ – V4Vendetta 2012-03-02 11:43:56
當我設置ObjectDataSource時，radgrid中的所有代碼都是自動生成的。所以，我認爲這是正確的！ – Slrg 2012-03-02 11:47:36
請使用堆棧跟蹤更新帖子，並且您是否正在做特別的選擇？ – V4Vendetta 2012-03-02 11:53:58
