Rating

The Rating control provides the ability to select and display ratings. It represents a container of RatingItem objects, which can be selected and deselected.  

Server side

• Getting and setting the control's value
  Use the Rating.Value property to get or set the control's current value.
  
  
• Customizing the control
  The number of items, displayed in the Rating control can be specified either by setting the ItemsCount property to the desired value or by defining individual items. If the ItemsCount property is used, the items will be created automatically and their images will be set according to the specified Theme. The default images can be changed on the root level by setting the ItemsImageUrl, ItemsActiveImageUrl, ItemsSelectedImageUrl and ItemsActiveSelectedImageUrl properties.
  By defining individual items you can customize the appearance of the control by setting specific images to the different items. If the defined items count is less then the specified ItemsCount, the control will generate additional items with the default settings until the value of ItemsCount is reached.  
  Items can be arranged horizontally or vertically by setting the Orientation property.
  The Rating control supports three different selection modes, defined in the RatingMode enumeration.
