This example shows how to use the CesiumExt.data.store.DataSourceStore class:

• Each Change in the Grid Panel will be reflected in Cesium.DataSource and Cesium.DataSourceCollection instances.
• And each change on Cesium.DataSource and Cesium.DataSourceCollection will also be reflected in the Grid Panel.

Remark: Double click in the Grid Row to edit the Cesium DataSource.

Have a look at dataSource.js to see how this is done.
