ASP.NET配置数据源是不是返回任何东西?

标签: asp.net sql database data-binding

我正在选择当前用户的表格数据:

SELECT [ConfidenceLevel], [LoveLevel], [HappinessLevel] FROM [UserData] WHERE ([UserProfileID] = @UserProfileID)

我已将控件设置为唯一的用户ID,并且它获得了正确的值:

HTML: <asp:Label ID="userID" runat="server" Text="Labeluser"></asp:Label>

C#: userID.Text = Membership.GetUser().ProviderUserKey.ToString();  

然后我使用Configure Data Source窗口在where子句中使用它 唯一ID =控制然后controlID userID (填写.text给我)

我编译并运行但没有显示表应该在哪里。有什么建议?

以下是它创建的代码:

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
    DataSourceID="SqlDataSource1">
    <Columns>
        <asp:BoundField DataField="ConfidenceLevel" HeaderText="ConfidenceLevel" 
            SortExpression="ConfidenceLevel" />
        <asp:BoundField DataField="LoveLevel" HeaderText="LoveLevel" 
            SortExpression="LoveLevel" />
        <asp:BoundField DataField="HappinessLevel" HeaderText="HappinessLevel" 
            SortExpression="HappinessLevel" />
    </Columns>
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:ConnectionStringToDB %>" 
    SelectCommand="SELECT [ConfidenceLevel], [LoveLevel], [HappinessLevel] FROM [UserData] WHERE ([UserProfileID] = @UserProfileID)">
    <SelectParameters>
        <asp:ControlParameter ControlID="userID" Name="UserProfileID" 
            PropertyName="Text" Type="Object" />
    </SelectParameters>
</asp:SqlDataSource>

我已经在asp.net页面上回答了,但如果你没看到那个我也会在这里做...

取出对sqldatasource代码生成的“对象”的任何引用......

应该是:

            PropertyName =“Text”/&gt;

如果你有更新并插入和删除,你也必须从那里删除它......
