This example demonstrates how to incorporate RadRating into RadGrid. This way the user can rate the items loaded in the Grid. You can choose whether or not to allow a single user to rate an item more than once. The example allows an item to be rated only once. The respective Rating control becomes read-only (i.e. RadRating1.ReadOnly = true), after the item has been rated.

Please note that the changes in the data will be persisted per Session only. The data will be reset next time you visit the page.

The user is allowed to rate an item only once. The respective Rating control becomes read-only after the item is rated.
