You should be able to change the header cells after you've set the datasource:

    if (dataGridView1.Columns["Value"] != null)
        dataGridView1.Columns["Value"].HeaderText = "Key";
    if (dataGridView1.Columns["Expiration"] != null)
        dataGridView1.Columns["Expiration"].HeaderText = "Expire";
