ASP.NET ListView with DataPager throwing error after going to next page

Question

Hi guys, I have a problem in ListView with DataPager.

I have SqlDataSource

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

and it was binded in ListView. I set my PageSize in DataPager to 5, so after navigating to next page.

It thrown an error

Procedure or function usp_posts_getall has too many arguments specified

in my usp_posts_getall, I only have 1 parameter

@thisCategoryID int

What went wrong?

ok sorry,

I forgot to clear the SelectParameters because in my Page_Load, I have this code:

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

        SqlDataSource1.SelectParameters.Clear();  // <<--- and I forgot this
        SqlDataSource1.SelectParameters.Add(param);

it's working now
