c# - 在 ASPX 页面上获取 'too many parameters passed' 到存储过程

Question

我无法弄清楚这个错误。我在 ASPX 页面上有一个网格，用于显示 SQL Server 2008 数据库中存储过程的数据。当页面加载时，我收到以下错误:

"Procedure or function <sp_name> has too many arguments specified."

这是网格和数据源的代码:

<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AutoGenerateColumns="False"
        DataSourceID="SqlDataSource1" ShowFooter="True" OnRowDataBound="GridView1_RowDataBound"
        AllowSorting="True">
        <Columns>
            <asp:BoundField DataField="MerchantID" HeaderText="ID" InsertVisible="False" ReadOnly="True"
                SortExpression="MerchantID" />
            <asp:BoundField DataField="MerchantName" HeaderText="Merchant" SortExpression="MerchantName" />
            <asp:BoundField DataField="RapidTuitionID" HeaderText="RapidTuition ID" SortExpression="RapidTuitionID" />
            <asp:BoundField DataField="DateCreated" HeaderText="Enrolled" SortExpression="DateCreated" />
            <asp:TemplateField HeaderText="Commands">
                <ItemTemplate>
                    <asp:LinkButton ID="ImpersonateUserLinkButton" runat="server" OnClick="Command_Click"
                        CommandName="impersonate" CommandArgument='<%# Eval("MerchantID") %>' CssClass="table_command">Impersonate</asp:LinkButton>
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
        <EmptyDataTemplate>
            No data to display.
        </EmptyDataTemplate>
        <PagerStyle CssClass="pager" />
    </asp:GridView>
    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:Development %>"
        SelectCommand="sp_GatewayMerchants" SelectCommandType="StoredProcedure">
        <SelectParameters>
            <asp:ControlParameter ControlID="PromotionPlaceHolderTop$StartDate" Name="StartDate"
                DefaultValue="1/1/2010" PropertyName="Text" Type="DateTime" />
            <asp:ControlParameter ControlID="PromotionPlaceHolderTop$EndDate" Name="EndDate"
                DefaultValue="12/31/2010" PropertyName="Text" Type="DateTime" />
            <asp:ControlParameter ControlID="PromotionPlaceHolderTop$StatusActive" DefaultValue="true"
                Name="StatusActive" PropertyName="Checked" Type="Boolean" />
            <asp:ControlParameter ControlID="PromotionPlaceHolderTop$StatusDeactive" DefaultValue="true"
                Name="StatusDeactive" PropertyName="Checked" Type="Boolean" />
        </SelectParameters>
    </asp:SqlDataSource>

这是存储过程的代码:

ALTER PROCEDURE [dbo].[sp_GatewayMerchants] 
    -- Add the parameters for the stored procedure here
    @StartDate DateTime, 
    @EndDate DateTime,
    @StatusActive bit,
    @StatusDeactive bit
AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;

    -- Insert statements for procedure here
    SELECT 
        m.MerchantID AS [ID],
        m.MerchantName,
        CASE m.StatusFlag WHEN 1 THEN 'Active' ELSE 'Deactive' END AS [Status],
        m.RapidTuitionID,
        m.DateCreated
    FROM
        Merchant m
    WHERE
        (CONVERT(varchar,m.DateCreated,112) BETWEEN CONVERT(varchar,CONVERT(DATETIME,@StartDate,101),112) AND CONVERT(varchar,CONVERT(DATETIME,@EndDate,101),112))
        AND
        (
            (@StatusActive = 1 AND m.StatusFlag = 1)
            OR 
            (@StatusDeactive = 1 AND m.StatusFlag = 0)
        )
    ORDER BY
        m.MerchantName
END

数据源传递 4 个参数，存储过程接受 4 个参数，但是当页面显示时，我收到上述错误。我在这里遗漏了什么吗？

编辑:这是模板列后面的代码。但我不确定这如何导致 SP 出现额外的参数。

        protected void Command_Click(object sender, EventArgs e)
    {
        var merchantID = Convert.ToInt32(((LinkButton)sender).CommandArgument);

        switch (((LinkButton)sender).CommandName)
        {
            case "impersonate":
                var gs = GatewaySession.Parse(Page.User.Identity.Name);
                gs.Role = GatewaySession.RoleEnum.Merchant;
                gs.MerchantID = merchantID;
                gs.CustomerID = -1;

                FormsAuthentication.SetAuthCookie(gs.ToString(), false);

                Page.Session["MerchantID"] = gs.MerchantID;

                Response.Redirect("/Merchant/Default.aspx");
                break;
        }
    }

如果我删除 ASP:LINKBUTTON 代码就可以工作。那么为什么 LINKBUTTON 会导致这种情况呢？

使用 Profiler 并检查哪些参数真正传递给 SP。
