Examples of com.extjs.gxt.ui.client.store.Record

com.extjs.gxt.ui.client.store.Record
Records wrap model instances and provide specialized editing features, including modification tracking and editing capabilities.
Rather than editing a model from a store directly, record can be used to "buffer" any changes to the model. Changes can be "committed" or "rejected" at both the record and store level.
Record instances can be retrieved from the container store by calling @link {@link Store#getRecord(ModelData)}. To get a list of modified records call @link {@link Store#getModifiedRecords()}. Code snippet:
```
 Record record = store.getRecord(store.getAt(0)); record.set("foo", "bar"); List<Record> modified = store.getModifiedRecords(); for (Record r : modified) { } store.commitChanges(); 
```

      stopEditing(true);
    }


    hideTooltip();
    M model = (M) grid.getStore().getAt(rowIndex);
    Record r = getRecord(model);
    RowEditorEvent ree = new RowEditorEvent(this, rowIndex);
    ree.setRecord(r);


    Element row = (Element) grid.getView().getRow(rowIndex);
