Question

我被分配将旧版本的一些.Net项目转换为.net 4.0版本。我使用ODAC驱动程序替换ODBC驱动程序。一切顺利，直到我发现gridview的问题，当我尝试删除一行时，我得到非法字符Oracle异常。 gridview位于更新面板中。我收到的异常是Microsoft Jscript运行时错误：Sys.WebForms.PageRequestManagerServerErrorException：ORA-00911：无效字符。以下是网格视图和sqldatasource的代码。 linkbutton使用sqldatasource的delete参数触发删除。

Answer 2

我找到了一个使用网格视图的行删除事件的简单替代方法。我刚删除了asp页面的sqldatasource中的删除参数，然后将冲突检测设置为覆盖更改。

    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()

删除gridview行时出现无效字符错误
