Keep page number on Datatable

[phenrir]

Hi,

I'm using a datatable with (client side) pagination and I'd need to store the current page number of the table.
What I want is that when the user navigates to another page and then comes back to the page where the datatable is, the table
is on the same page it was before.

I've seen the attribute "page" of the datable and I think it will be useful for this, but I don't know how can I retrieve the page number from the table or, instead, detect the user's clicks on forward and backward buttons.

Can anyone help me?
Thanks a lot!

Nobody? I'm kinda lost

I would guess your best bet is to use jQuery to hook the onclick event for the paginator buttons. You'll probably want to use the proxying pattern shown on the jQuery website to ensure the current functionality attached to the buttons still executes. But you could proxy the onclick, and then add in an Ajax call to your bean.

Hope that gives an idea?

Cheers,

Matt

Code: Select all

yourdatatableWidgetVar.getPaginator().getPage()

Also PrimeFaces datatable does not do client side pagination (it was before), it does ajax pagination only.

Hello,

By the way, the documenation doesn't mention that paginator is an Yahoo paginator. You can call all available methods on Yahoo paginator http://developer.yahoo.com/yui/docs/mod ... nator.html after you got it with dataTableWidget.getPaginator(). You can even register a callback 'changeRequest' firing with pagination and update all stuff you need via p:remoteCommand in your callback.

Should it not be

Code: Select all

var pagActual = tablaWidget.getPaginator().getCurrentPage();

?

I don't get it...
I'm trying to figure out how to get the datatble page in the backbean like you're explaining but .... i don't understand.
You say you can use the widgervar.getPaginator.getPage(), but how can i pass that value to the bean?

Hi,

Did you get this to work?
Do we have to do it in the JavaScript?
In my case, I have a back button on my application to go back to the data table after navigating to the detail page.
How can I set the page value in this case?

Code: Select all

yourdatatableWidgetVar.getPaginator().getPage()

what is the yourdatatableWidgetVar object? I tried Widget, which did not work.

Thanks
Vinaya

Page attribute works read only at the moment, feel free to create an issue ticket so we can work on this to update the bound value to the page attribute like page="#{bean.value}".
