Five records to display on the label

Question

Hi,

I have a table, datagridview and a label on my form. 

I need to display five records on my label one by one with 2 segunds of interval between them. How can I do? 

 

ID | each_number 

______________ 

1               1

2               2

3               3

4               4

5               5

if (e.RowIndex >= 0)
{
    DataGridViewRow row = this.dgvPGC.Rows[e.RowIndex];
    if (dgvPGC != null)
       lblNumber.Text = row.Cells["each_number"].Value.ToString();
}

 Then to display it as I said before on the label I need to click on a button.
