Answer 1

Try this :

int sum = 0;
for (int i = 0; i < dataGridView1.Rows.Count; ++i)
{
   sum += Convert.ToInt32(dataGridView1.Rows[i].Cells[1].Value);
}

Answer 2

LoadingRow event gives you the current DataGridRow , so you need to access the corresponding Item to that DataGridRow .

So, Change this

   string s = dataGrid1.Columns[2].GetCellContent(e.Row).ToString();

to something similar to :

   MyItem item = Dgrd.ItemContainerGenerator.ItemFromContainer(e.Row) as MyItem;
   if (item != null)
   {
       System.Diagnostics.Debug.WriteLine(item.Name);
   }

or,

    MyItem i =  e.Row.DataContext as MyItem;        
    if (item != null)
    {
        System.Diagnostics.Debug.WriteLine(item.Sku);
    }
