In your original code, You have the .Tostring in the wrong place. The way you have it, you are trying to ".ToString" the .ADD method of the columns collection of the datagridview. I assume you what to "ToString" the brandID. So change the code to...

Code:

---

public void FillBrandMaster(){
            foreach (Brand _brand in _brands)
                dataGridView1.Columns.Add(_brand.BrandID.ToString());               


        }
