I am saving in Database and getting the ID back of the row saved in the database.  The Information is saved in the database but the ID doesnt come.  The interger which is supposed to have the integer is always -1

any suggestions
SQL in Datalist (DAL):
INSERT INTO [reiter] ([Vorname], [Nachname], [Verein], [Land], [Pferd_name], [Pferd_ID], [Pferd_herkunftsland]) VALUES (@Vorname, @Nachname, @Verein, @Land, @Pferd_name, @Pferd_ID, @Pferd_herkunftsland);

SELECT SCOPE_IDENTITY()

functions in BBL
[System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Select, false)]
    public DAL.reiterDataTable getReiterByReiterID(int reiterid)
    {
        return Adapter.GetReiterByID(reiterid);
    }
   
    [System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Insert, true)]
    public int InsertReiter(string Vorname, string Nachname, string Verein, string Land, string Pferd_name, string Pferd_ID, string Pferd_herkunftsland)
    {

        int localreiterID = Convert.ToInt32(Adapter.InsertReiter(Vorname, Nachname, Verein, Land, Pferd_name, Pferd_ID, Pferd_herkunftsland));
        return localreiterID;        
    }
Presentation layer
ObjectDataSource1.InsertParameters["vorname"].DefaultValue = Vorname.Text;
        ObjectDataSource1.InsertParameters["nachname"].DefaultValue = Nachname.Text;
        ObjectDataSource1.InsertParameters["verein"].DefaultValue = Verein.Text;
        ObjectDataSource1.InsertParameters["land"].DefaultValue = Land.Text;
        ObjectDataSource1.InsertParameters["Pferd_name"].DefaultValue = Name.Text;
        ObjectDataSource1.InsertParameters["Pferd_ID"].DefaultValue = FeifID.Text;
        ObjectDataSource1.InsertParameters["Pferd_herkunftsland"].DefaultValue = Pferd_Land.Text;
        int reiterint =  ObjectDataSource1.Insert();
        Nachname.Text = reiterint.ToString();:

DECLARE @RV INTEGER
SET @RV=SCOPE_IDENTITY()
RETURN @RV             <--this is what sends it back

im using visual studio (im new with this) do i put this instead of "select scop...()" in the sql query.  secondly: do you really think the sql queryis  reason for the false ID returned (is always -1).  I´ve used it in other situations with success????

Yes, it goes in the TSQL stored procedure, instead of "select scope..."
