how to refresh parent page when I use SP.UI.ModalDialog.OpenPopUpPage?
function OpenCustomDialog(dialogUrl, dialogWidth, dialogHeight, dialogTitle, dialogAllowMaximize, dialogShowClose) {

    var options = {
        url: dialogUrl,
        allowMaximize: dialogAllowMaximize,
        showClose: dialogShowClose,
        width: dialogWidth,
        height: dialogHeight,
        title: dialogTitle,
        dialogReturnValueCallback: Function.createDelegate(null, CloseCallback3)
    };
    SP.UI.ModalDialog.showModalDialog(options);
}

SP.UI.ModalDialog.OpenPopUpPage(dialogUrl, null, dialogWidth, dialogHeight);

function CustomPageRefresh(dialogResult, returnValue) {
    document.location.reload(); //or another method you need to refresh the page in your case
}

function OpenPopupInDialog(dialogUrl, dialogWidth, dialogHeight) {
    SP.UI.ModalDialog.OpenPopUpPage(dialogUrl, CustomPageRefresh, dialogWidth, dialogHeight);
}
