The [TestCaseSource] attribute will allow you to do this. You can create a function that returns an enumerable list of test cases

public IEnumerable GetTestCases()
{
    SqlDataAdapter da = new SqlDataAdapter("Select * From GetProductDetailsTest;", Connection);
    Database1DataSet.GetProductDetailsTestDataTable dt = new Database1DataSet.GetProductDetailsTestDataTable();
    da.Fill(dt);

    foreach (Database1DataSet.GetProductDetailsTestRow dr in dt.Rows)
    {
        yield return dr;
    }
}

then you can pass a TestCaseSource in:

    [Test, TestCaseSource("GetTestCases")]
    public void GetProductDetailsTest(Database1DataSet.GetProductDetailsTestRow dr)
    {
        if (pm.GetProductById(dr.productId) == null)
            Assert.Fail("Id of test case: " + dr.id + ", Product id of failure: " + dr.productId);
        }
    }
