Page Rating example using Page Objects
At the EPiServer Techforum in Oslo last week, I showed a quick and dirty page rating feature for CMS 6 using Page Objects and Dynamic Content. The source code for that can be found here .
The project consists of 3 class:
- The Rating object. This is the Page Object that holds the rating data for the page
- The RatingDC which provides the IDynamicContent implementation
- The RatingControl which is the Dynamic Content User Interface control.
To test it out, copy the Rating assembly dll to a CMS RC1 site’s bin folder. Create a Rating folder under the site root folder and then copy the RatingControl.ascx to that. Under that folder create a folder called Images. To that folder copy the star.png file.
You will then need to register the Dynamic Content in the site’s episerver.config file as shown below:
<dynamicContent> <controls> <add description="Displays a Rating facility" name="Rating" type="EPiServer.Samples.RatingDC, Rating" /> </controls> </dynamicContent>

What happens with the cached PageData object when the page is saved using the same version? Is it left unchanged or removed from the cache?
Hi,
At the moment all changes to page objects will involve the affected page being removed from the cache. We hope to make some small changes before CMS 6 is released so if only the actual object has changed (the item that is stored in the Dynamic Data Store) then we do not need to save the PageData and therefore the cache remains in tact.
Obviously, if new page objects are added or existing ones removed from the PageObjects collection on PageData that a save is required and the cache will still be emptied.

Sounds good :) Removing the page from cache everytime someone votes wouldn't be very optimal, looking forward to the release of CMS6.
