[英]GridView: Database error when running on server, works fine on localhost
我正在一個項目中，我必須在gridview中返回以下列，並且可以通過0-7過濾器縮小搜索范圍。
我可以在本地計算機上完成此操作，但是它返回錯誤，提示我在服務器上運行它時無法在數據庫源中找到ProjectTitle字段。 其余的代碼很好，因為當我從GridView中刪除ProjectTitle列時沒有顯示錯誤。 以下是我的代碼。

有什么建議會導致這種情況嗎？
您確定遠程數據庫包含字段ProjectTitle嗎？
如果更改localhost連接字符串localhost，以便它使用遠程數據庫（但仍使用localhost項目），您是否還會收到錯誤消息？ （這將確定問題是在代碼中還是在數據庫中。）
