Use the command with care, many actions in components are linked through events.

The most common use-case - preventing a component from repainting with each small operation:

//will repaint component 3 times


grid.add({ text:'111'});
grid.add({ text:'222'});
grid.add({ text:'333'});


//will repaint component only once
grid.data.blockEvent();
grid.add({ text:'111'});
grid.add({ text:'222'});
grid.add({ text:'333'});
grid.data.unblockEvent();
grid.refresh();
