Question

我刚接手一个asp.net/vb网站，我肯定还在学习。我收到以下错误：BC30451：未声明'ByOwner'。由于其保护级别，它可能无法访问。

我用：

调用数据源

<asp:GridView ID="CaseCountByOwner" runat="server" AllowSorting="true" DataSourceID="ByOwner"

以下是代码文件中的内容：

    HitMe.AddHit(Request.UserHostAddress, Request.UserAgent, Request.Url.ToString)

    If user.Length() = 0 Then
        Return
    Else

非常感谢任何帮助，更值得赞赏的是一个关于开始使用.net应用程序的良好资源的链接。

Answer 1

您需要在页面中的某处SqlDataSource使用ID“ByOwner”

例如：

<asp:SqlDataSource ID="ByOwner" runat="server" />

请注意，您声明GridView的数据源为“ByOwner”。

Answer 2

我建议你使用SP，而不是在sql中编写硬编码查询，你可以编写存储过程，这将给出最佳结果。

Stored Procedure

Stored Procedure with C#

Stored procedure to return scalar values

Answer 3

您需要找到声明对象ByOwner的位置。是否有一个控件在同一页上具有ByOwner的ID属性？

如何使命令可访问？
