The Rating control allows your users to add customized rating capability to their applications. The control allows you to display rating images to the end users and record their input when they tap on an image.
It stores the current rating (value). It is set when the user tap on a RatingItem (usually displayed as a star). It also can be set by code, for example, to show decimal values.
It stores the user’s average rating. The average value is determined by the value specified for each rating item. This is determined by setting the Value property for each RatingItem object in the RatingItems collection. The average value is then calculated based on which item was clicked and the number of clicks (RatingCount).
It stores how many times the user has voted.
Display the Rating control horizontally or vertically.
