DataStore + Grid + SmartRender

Can grid load data from dataStore with smartRendering?
I used both dataStore and smartRendering ,but when I’m scrolling,I find some rows not showing.
Does dataStore and smartRendering work with each other friendly?

my code as below:

mygrid.init();
mygrid.enableSmartRendering(true, 50);
var jsonList = eval('json.' + listKey);
myGridDataStore =  new dhtmlXDataStore();
myGridDataStore.parse(jsonList);
mygrid.sync(myGridDataStore);

Unfortunately your issue cannot be reconstructed locally.
The grid synced with datastore should work well with smart rendering.
If issue still occurs - please, provide a complete demo where the issue can be reconstructed to support.dhtmlx.com.
