SharePoint javascript refresh page is reloading the whole page

Question

In a webpart, I added a button that should trigger a modal dialog, and display a message when the dialog is closed.

The dialog script is handled by this code :

function OpenGenericForm(formUrl, confirmText) {
    ExecuteOrDelayUntilScriptLoaded(function () {
        SP.UI.ModalDialog.showModalDialog({
            url: formUrl,
            dialogReturnValueCallback: function (dialogResult, returnVlue) {
                RefreshPage(dialogResult);
                if (dialogResult == SP.UI.DialogResult.OK) {
                    SP.UI.Notify.addNotification(confirmText, true);
                }
            } 
        });
    }, 'sp.js');
}

And the button is :

<a id="someid" onclick="OpenGenericForm('/Lists/gen test/NewForm.aspx','some message');return false;" href="#">label of the link</a>

The modal is opened as expected, but when it closes, I can see the notification a quarter of seconds, before the whole page is reloaded (and then my notification disappeared.

Isn't a call to RefreshPage(dialogResult) supposed to reload the page using some kind of ajax?

If not, what the correct way to reload content of webparts using ajax?

Answer 1

function portal_openModalDialogContact(URL) {
    var options = SP.UI.$create_DialogOptions();
    options.url = URL;
    options.width = 600;
    options.dialogReturnValueCallback = Function.createDelegate(null, CloseCallback);
    SP.UI.ModalDialog.showModalDialog(options);
}
function CloseCallback(result, target) {

    window.parent.location.href = window.location.href; //This will refresh your page after popup got closed
} 

This will solve your problem

RefreshPage tells the browser to reload the whole page. You would need to use some functionality like in this post to reload update panels (if your webpart content is not in an update panel, it will reload the whole page regardless): http://encosia.com/easily-refresh-an-updatepanel-using-javascript/

The example from the article uses:

<div id="Container" onclick="__doPostBack('UpdatePanel1', '');">
