Instant Feedback Mode
- 2 minutes to read
The DevExpress Grid Control for Silverlight includes support for multiple binding modes, each designed to address a specific problem and to make working with data easier and faster. Alongside the standard binding mode, the grid also provides the Instant Feedback UI Mode.
Instant Feedback Mode is an asynchronous mode. With this mode, you will no longer experience any UI freezing as data operations will be performed asynchronously, in a background thread. This results in a Grid Control and application that will always remain highly responsive. The user can continue to scroll through records, and even re-sort, re-group and re-filter the control's data.
To activate this feature, use our specially designed data source - or DevExpress.Xpf.Core.ServerMode.RiaInstantFeedbackDataSource. To see the Instant Feedback mode in action, take a look at the RIA Instant Feedback module in the Silverlight DXGrid Main Demo.

The grid control provides two events that fire after asynchronous data loading has been started and completed. These events are: GridControl.AsyncOperationStarted and GridControl.AsyncOperationCompleted. The GridControl.IsAsyncOperationInProgress property indicates the current status of asynchronous data loading.
