DataSource Caching Modes

GridGroupingControl provides built-in support for data caching. This prevents the need for querying the data from the datasource for every postback and callback roundtrip and thus improves the grid performance by reducing the load time. GridGroupingControl provides two such caching modes as given below.

• ViewState - The datasource object will be serialized and added to view state.
• Session - The datasource object is added to session
• None - This option turns off data caching and the datasource must be initialized for every postback and callback.
