Returnvalue Not Accepted In Update / Delete Command

Hi,

I tried to use the RETURN_VALUE of a stored procedure in updata / delete commands with a sql-datasource and a stored procedure.

The thing works fine with the insert command.
But it fails with "too many arguments..." in delete / update.

I also tried to handle the updating event like this:


protected void sqldsReportSelect_Updating(object sender, SqlDataSourceCommandEventArgs e) {
   SqlParameter sqP = new SqlParameter("RETURN_VALUE", SqlDbType.Int);
   sqP.Direction = ParameterDirection.ReturnValue;
   e.Command.Parameters.Add(sqP);
}

It brings the same error.

Do I make something wrong or is this a bug?

Regards

Manfred
