You need to post the code you're using to insert the product, also do you have any indexes on the Product table?

Try with giving it a Product ID, that must be unique to the each product in your database.
In you code while inserting new Product, catch the exception as follows

C#

try
{
    /*
    Some code for inserting record
    */
}
catch(SqlException ex)
{
    if (ex.Number == 2627)
    {
        MessageBox.Show("Productis already there!");
    }
}

Error Number 2627 for MS-SQL server is for the violation of Unique-Key
Constraint.
