Let's take a look at the problems discussed in this chapter:
The rating system included in the package of the ASP.NET AJAX controls works very well for a flat rating system. It has no issues with showing five stars horizontally or vertically, providing simple mouse over capabilities, capturing click events, and providing several properties to capture the selected input. What it doesn't do well is provide you with a way to capture multiple subratings for a piece of content. That is what we will build here! Clicking on the rate this link will throw up a modal window.
In the modal window, the user will have several dynamically generated attributes to apply individual ratings to. All these ratings are then aggregated to provide the final rating for that item.
Once we have received the rating for an item, we will thank the user for his/her input.
With the next view of this item, we will display the average rating.
