How to detect DataGridView CheckBox event change?

Question

I have a winforms app and want to trigger some code when a checkbox embedded in a DataGridView control is checked / unchecked. Every event I have tried either

Answer 1

The Code will loop in DataGridView and Will check if CheckBox Column is Checked

private void dgv1_CellMouseUp(object sender, DataGridViewCellMouseEventArgs e)
{
    if (e.ColumnIndex == 0 && e.RowIndex > -1)
    {
        dgv1.CommitEdit(DataGridViewDataErrorContexts.Commit);
        var i = 0;
        foreach (DataGridViewRow row in dgv1.Rows)
        {
            if (Convert.ToBoolean(row.Cells[0].Value))
            {
                i++;
            }
        }

        //Enable Button1 if Checkbox is Checked
        if (i > 0)
        {
            Button1.Enabled = true;
        }
        else
        {
            Button1.Enabled = false;
        }
    }
}
