Instant Feedback™ UI Mode
The DevExpress Silverlight Grid Control includes support for multiple binding modes, each designed to address a specific use case and to make working with data easier and faster.
Alongside the standard binding mode which is effective when working with small to medium sized datasets, the Silverlight Grid also provides the Instant Feedback™ UI mode that should be used for large datasets.
Instant Feedback™ UI Mode can be used with WCF RIA Services.
When you activate Instant Feedback™ UI mode, your end-users will no longer experience any UI lock-ups.
Data operations will be performed asynchronously - in a background thread - and both the Grid Control and your application
will always remain responsive to end-user actions.
The following animation demonstrates Instant Feedback™ UI Mode (the data source contains 1.6 million records).
During processing, the Silverlight Grid can optionally provide visual feedback for end-users.
By default, a dedicated indicator button is displayed to the left of column headers.
Optionally, a specialized panel can be displayed above the Grid while loading data asynchronously.
To activate this feature, use our data source - XPInstantFeedbackSource or RiaInstantFeedbackDataSource.
