Refresh don't update the values. To update the values set the updated values in the groupbox again.

Here's a sample to help you

foreach (Control ctrl in this.Controls) {
    switch (ctrl.GetType) {
        case typeof(TextBox):
            ((TextBox)ctrl).Text = string.Empty;
            break;
        case typeof(ComboBox):
            ((ComboBox)ctrl).Items.Clear();
            break;
        default:
            throw new Exception("This type of control is not handled!!! Need to add a case for type " + ctrl.GetType.ToString);
    }
}
