Hi Luther,
If I add a few values to a page <div ala an Ajax button - and the user hits
refresh on the page, the new values I've added go away.
The user is completing a form - but hasn't formally submitted the form yet -
so there is nothing stored in the database yet. The browser naturally
re-renders the <textarea and <input values to the screen - but wipes out
content to any <divs I might have dynamically added data to.
There is a DOM event on 'unload' on the <body> tag that can be used to
notify the user about what will happen in this case; i.e. they will lose
the data they have entered if they refresh.
Have a look at ModalWindow since it implements an unload event for just
this case.
It seems like you should be able to add an AttributeModifier on the body
tag and then craft an interface where you particular component can
contribute a javascript callback to the main unload callback maybe via
an IModel<String>.
Another option if your forms are small enough is to just push an ajax
get request with customized parameters or
AjaxFormComponentUpdatingBehavior when the data is changed (i.e. bind
the callback to the 'onblur' event) This will populate the server side
models and allow a rerender to work properly.
Regards,
Mike
