}

private void ApplyValidationSummarySettings() {
    vsValidationSummary1.RenderMode = (ValidationSummaryRenderMode)Enum.Parse(typeof
        (ValidationSummaryRenderMode), rblRenderMode.SelectedItem.Value.ToString());
    vsValidationSummary1.ShowErrorAsLink = chbShowErrorAsLink.Checked;
}

private void ApplyEditorsSettings() {
    ASPxEdit[] editors = new ASPxEdit[] { tbName, tbEmail };
    foreach(ASPxEdit editor in editors) {
        editor.ValidationSettings.ValidateOnLeave = chbValidateOnLeave.Checked;
        editor.ValidationSettings.SetFocusOnError = chbSetFocusOnError.Checked;
    }
}
