Real-Time Updates

The DataGrid component is optimized for real-time updates. You should bind it to a DataSource that contains a store and use the push(changes) method to update the store's data. The rows with changed data are rerendered (see the DataGrid's repaintChangesOnly property). The DataSource object also provides properties that control its behavior when it receives a push. For example, reshapeOnPush is set to true in this demo to allow summaries to be recalculated.

Grids in the detail sections are updated in real time as well. All the grids share the same ordersStore that receives pushes, but it is filtered to show only a specific product's orders for each grid.
