        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        Response.Cache.SetExpires(DateTime.Now.AddSeconds(-1));
        Response.Cache.SetNoStore();
    %>
        <p>
            <table style="width:100%;">
                <tr>

<UpdateParameters>
                <asp:Parameter Name="UserName" Type="Int32" />
                <asp:Parameter Name="UserPrivilegeName" Type="String" />
                <asp:Parameter Name="UserPassword" Type="String" />
                <asp:Parameter Name="UserPrivilegeId" Type="Int32" />
            </UpdateParameters>

您的参数名称是@UserPassword。

也许这就是问题。
