WebCore Grid Population Using XData without Aurelius

[wlandgraf (Wagner Landgraf)]

When invoking service operations with RawInvoke, you should manually set the data to the dataset:

Loading Batch Move XData Stream Query to XDataWebDataSet - Web Core App

But for TXDataWebClient check this link https://doc.tmssoftware.com/biz/xdata/guide/web.html#loading-data-manually XDataWebDataset1.SetJsonData(Response.Result); XDataWebDataset1.Open;

Here is a small example:

Display request of XDataWebClient in WebDbGrid

I have an XDataWebClient via which WebInvoke Json data is requested. This data should be passed to an XDataWebDataSet with XDataWebDataSet.SetJsonData for display in the WebDBGrid. procedure TfClientDatamodul.LoadOrders;  procedure OnSuccess(Response: TXDataClientResponse);  begin    XDataWebDataSetOrders.Close;    //XDataWebDataSetOrders.Connection:=NIL;    //XDataWebDataSetOrders.EntitySetName:='';    XDataWebDataSetOrders.SetJsonData(Response.Result);    XDataWebDataSetOrders.Open;  end;beg…

Web Core / XData Service Query Example

Being new to Web Core and XData, I've been very much impressed at how well everything works. Mixing JS and Delphi code in particular has been endlessly entertaining and super useful for tweaking UI web elements. Setting up new XData services is also amazingly simple and straighforward. Overall it has been as more fun developing in this sandbox than any I can recall! All good. It isn't perfect however, so this post is about outlining how to get a Query from the XData server into Web Core in …

Basically:

1. Use TXDataWebClient to retrieve data from the server directly using more flexible methods (like List). TXDataWebClient also provides you with async-flagged methods, meaning you can call them using await. There is a demo in XData installation folder (\demos\web\clientAsync) that shows how to use it. Once you get data from the client, you can put it in the dataset using SetJsonData and then you can call Open to iterate through the dataset.

procedure TfClientDatamodul.LoadOrders;
  procedure OnSuccess(Response: TXDataClientResponse);
  begin
    XDataWebDataSetOrders.Close;
    //XDataWebDataSetOrders.Connection:=NIL;
    //XDataWebDataSetOrders.EntitySetName:='';
    XDataWebDataSetOrders.SetJsonData(Response.Result);
    XDataWebDataSetOrders.Open;
  end;
begin
  XDataWebClientOrders.RawInvoke('IOrderService.GetOrders', ['10/10/2018', '10/10/2019'], @OnSuccess);
end;
