Hi,
Currently we are evaluating Html Elements and are planning to use its professional version.
We are stuck with below problem.
Currently we use ngRx Stores, Actions, Reducers to request, process, retrieve  the data for example –

1. Request –
   <div>
   <div>this.store.dispatch(new FileAction.GetGridData(payload))</div>
   <div>2. Response – is store with subscribe</div>
   </div>
   <div>
   <div>this.store.select(‘data’).subscribe((state => {</div>
   <div>if (state.data) {</div>
   <div>if (state.data.data &&state.data.data.length >0) {</div>
   <div>this.data=JSON.parse(JSON.stringify(state.data.data));</div>
   <div>this.total=state.data.data_size;</div>
   <div>} else {</div>
   <div>this.data = [];</div>
   <div>this.total=0;</div>
   <div>}</div>
   <div>}</div>
   <div>}))</div>
   </div>
   <div></div>
   <div></div>
   <div></div>
   <div>Now we are planning to use Smart Element Grid for Request/Response. Can you guide how we can do that. FYI we are trying to follow</div>

We are not sure, how to update our code to make use for SmartGrid.
