我收到以下错误,我无法解决。
<%@ Page Language="VB" MasterPageFile ="~/Master.master" AutoEventWireup="false" CodeFile="test.aspx.vb" Inherits="test" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">
<asp:GridView ID="GridView1" PageSize ="50" runat="server" AllowPaging="True" AllowSorting="True"
AutoGenerateColumns="False" DataKeyNames="ID">
<Columns>
<asp:TemplateField HeaderText="ID">
<ItemTemplate>
<%# Container.DataItemIndex + 1 %>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="Dname" HeaderText="Player" SortExpression="Dname" />
<asp:BoundField DataField="City" HeaderText="City" SortExpression="City" />
<asp:BoundField DataField="GTScore" HeaderText="Score"
SortExpression="GTScore" />
</Columns>
</asp:GridView>
</asp:Content>
这是我的.aspx代码
Partial Class test
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim fDate As Date = New Date(Today.Year, Today.Month, 1)
Dim tDate As Date = New Date(Today.Year, Today.Month, Date.DaysInMonth(Today.Year, Today.Month))
GridView1.DataSource = Game.SelectToppersOfMonth1(fDate, tDate)
GridView1.DataBind()
End Sub
End Class
这是我的.aspx.vb代码。我只是从函数SelectToppersOfMonth1调用存储过程
我存储过程中的select查询是
SELECT TOP 100 A.[dispName] as [Dname], A.[city] as [City], SUM(B.[score]) as [GTScore]
FROM [Players] A,[Games] B
WHERE A.[ID]=B.[playerID] AND B.[startedOn] BETWEEN @fromDate AND @toDate
GROUP BY A.[dispName], A.[city] ORDER BY [GTScore] DESC
我收到错误

答案 0 :(得分:2)
只需从页面标记DataKeyNames="ID"
中删除它,因为您的查询未返回任何ID
列并且会破坏绑定。或者修改您的SQL
查询以返回ID列。

您在DataKeyNames属性中引用ID,它不在您的SQL查询中。这是正常的吗?
