Programmatically adding list to datagridview

Question

I have procedure that programmatically adding list to datagridview. For Example:

public List<Color_INFO> addrowtocolors()
{    
    List<Color_INFO> result = dal.GetColor();
    for (int i = 0; i < list.Count; i++)
    {
         var index = grdColors.Rows.Add();
         grdColors.Rows[index].Cells["Code"].Value = result[i].Code.ToString();
         grdColors.Rows[index].Cells["Desc"].Value = result[i].Desc.ToString();
    }
    return null;
}

But when I call it is adding 3 same rows to datagridview , and in list i have only one.

I know that I can use dataset option , but that not fit for my needs.

Thanx.

As per my comment... I've also removed the return value as it seemed strange to just return null. (or even the proposed list based on your function name).

public void addrowtocolors()
{    
    for (int i = 0; i < result.Count; i++)
    {
         var index = grdColors.Rows.Add();
         grdColors.Rows[index].Cells["Code"].Value = result[i].Code.ToString();
         grdColors.Rows[index].Cells["Desc"].Value = result[i].Desc.ToString();
    }
}

or

public void addrowtocolors()
{    
    for (int i = 0; i < list.Count; i++)
    {
         var index = grdColors.Rows.Add();
         grdColors.Rows[index].Cells["Code"].Value = list[i].Code.ToString();
         grdColors.Rows[index].Cells["Desc"].Value = list[i].Desc.ToString();
    }
}
