title: Simply retrieving all records from a store
body: <p>Instead of retrieving a single row of data from my store, how can I modify the following code to retrieve all records?</p>
  
  <pre><code>var store = Ext.data.StoreManager.lookup('MyStore');
          store.setProxy({
              type: 'pagingmemory',
              data: store.getAt(0)
            });
          store.load();
  </code></pre>
  
  <p>Any thoughts? </p>
