我在使用 DataPager 的 ListView 中遇到问题。

我有 SqlDataSource

<asp:SqlDataSource ID="SqlDataSource1" runat="server"
    ConnectionString="<%$ ConnectionStrings:ADSConnectionString %>"
    SelectCommand="usp_posts_getall" SelectCommandType="StoredProcedure">
</asp:SqlDataSource>

它被绑定在 ListView 中。我将 DataPager 中的 PageSize 设置为 5，因此在导航到下一页后。

它抛出了一个错误

过程或函数 usp_posts_getall 指定的参数过多

在我的usp_posts_getall中，我只有 1 个参数

@thisCategoryID 整数

什么地方出了错？

好的，对不起，

我忘了清除 SelectParameters，因为在我的 Page_Load 中，我有以下代码：

        参数 param = new Parameter();
        param.Name = "thisCategoryID";
        参数.Type = TypeCode.Int32;
        param.DefaultValue = SelectedCategoryID.ToString();

        SqlDataSource1.SelectParameters.Clear(); // <<--- 我忘了这个
        SqlDataSource1.SelectParameters.Add(param);

它现在正在工作
