How to get the combobox control value in a datagridview in windows form?

I am working with a windows app and have a form that contains a datagridview that has bound and unbound controls. My dropdowns have 2 parts - item and the value. (A = some value1; B = some value2, and so on). Item = A;B... Value = some value1; some value2.....

The user sees this in the dropdown - "some value1"

The value going into the subtable is: "A = somevalue1"

I need to enter Item "A" into the database table, but am having difficulty grabbing it.

The text fields load to the database fine. How do I get the correct value from the datagridview dropdowns?

I currently have:

for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
    for (int j = 0; j < dataGridView1.Columns.Count; j++)
    {
        if ((dataGridView1.Rows[i].Cells[j].Value != null) &&
             (dataGridView1.Rows[i].Cells[j].Value.ToString().Trim() != ""))
        {
            myRow[dataGridView1.Columns[j].Name.Trim()] = dataGridView1.Rows[i].Cells[j].Value.ToString().Trim();
            l_blnWrite = true;
        }
        else
        {
            l_blnWrite = false;
            break;
        }
    }
    if (!l_blnSavedRecord)
     {
         if(l_blnWrite)
             ds.Tables[l_strTable].Rows.Add(myRow);
     }
 }
