Iterate through specific col in DGVs' & compare the string values

I got 2 datagrid views, First datagrid 1st col or Index 0 & the Second datagrid 1st col or Index 0. How can i loop through a specific col in the datagridviews and look for the string values,if it matches with the list then go to a function.

My approach is not working. How can i do this?

private void b_calculate_Click(object sender, EventArgs e)
{           
    List<string> value = new List<String>() { "AE0", "AT1", "AT2", "AT3"};
    value = new List<string>(datagridview1.Columns[0].Index);
    List<string> value2 = new List<String>() { "BE0", "BT1", "BT2", "BT3"};
    value2 = new List<string>(datagridview2.Columns[0].Index);

     //First Combination
    if((value.ToString() == "AT1" || value.ToString() == "AE0" || 
         value.ToString() == "AT2")
          && 
         (value2.ToString() == "BT1" || value2.ToString() == "BE0"))
    { 
        gottoFunction1();
    }
    //Second Combination
    if((value.ToString() == "AT1" || value.ToString() == "AT2" )
            && 
           (value2.ToString() == "BT1" || value2.ToString() == "BT2"))
    { 
        gottoFunction2();
    }
}

Here's a routine that iterates through all available rows in both DataGridViews and does the processing shown in your method:

private void b_calculate_Click(object sender, EventArgs e)
{
    for (var i = 0; i < dataGridView1.RowCount; i++)
    {
        if (dataGridView2.RowCount <= i)
            break;

        var cellFromDG1 = dataGridView1.Rows[i].Cells[0];
        var cellFromDG2 = dataGridView1.Rows[i].Cells[0];

        if (cellFromDG1.Value == null || cellFromDG2.Value == null)
        {
            // this could be the empty row that allows you to
            // enter a new record
            continue;
        }

        var value = cellFromDG1.Value.ToString();
        var value2 = cellFromDG2.Value.ToString();

        if ((value == "AT1" || value == "AE0" || value == "AT2") &&
                (value2 == "BT1" || value2 == "BE0"))
        {
            gottoFunction1();
        }

        if ((value == "AT1" || value == "AT2") &&
            (value2 == "BT1" || value2 == "BT2"))
        {
            gottoFunction2();
        }
    }
}
