刪除gridview行時出現無效字符錯誤

Question

我被分配將舊版本的一些.Net項目轉換爲.net 4.0版本。我使用ODAC驅動程序替換ODBC驅動程序。一切都很順利，直到我發現GridView的問題，當我嘗試刪除一行時，我得到了非法字符Oracle異常。 gridview在更新面板內。我收到的異常是Microsoft Jscript運行時錯誤：Sys.WebForms.PageRequestManagerServerErrorException：ORA-00911：無效字符。以下是網格視圖和sqldatasource的代碼。 linkbutton使用sqldatasource的deleteparameters觸發刪除。

Answer 1

我發現使用網格視圖的行刪除事件容易替代。我只是刪除了ASP頁面的sqldatasource中的刪除參數，然後將衝突檢測設置爲覆蓋更改。

Sqldatasource1.DeleteCommand = "DELETE FROM code_owner WHERE code_owner_ID = :original_code_owner_ID" 
    Sqldatasource1.DeleteParameters.Add("original_code_owner_ID", GridView1.DataKeys(e.RowIndex).Values("code_owner_ID").ToString) 
    Sqldatasource1.Delete() 
    GridView1.DataBind() 

Answer 2

嘗試，敷瓦特/ BEGIN和END

BEGIN CODE_OWNER WHERE CODE_OWNER_ID = ? END
