How to show / display markers previusly added into UniMap?

[ElCherchu]

Hello developers

I working a project with TUnimaps and after adding the markers on the map, when closing and open the application they aren't longer there.

How can I show on the map the previously added markers?

Tranks.

I'm using delphi 10.2

Unigui 1.90.0.1555

Hi Hayri for your response.

I explain..

I open my Unigui application, I add one or severals markers to a UniMap, I close my application and when I open the application again all the markers I had added before desapears from map.

The question is, How to show the markers previosly added into the map.

Thank again..

Hi, You should save created markers to your database and load them when map is ready

Not, what is the most recommend way to do that?,

How can I get the Lat and Lon in the map?

thanks.

Please open "Unimap - Draw" Demo.

in UniMap1MarkerCreated you will have access to newly created Marker. 

you can check Marker.Latitude and Marker.Longitude properties.

Sorry Hayri in UniMap1MarkerCreated demo has

procedure TMainForm.UniMap1MarkerCreated(Sender: TObject;
  var Marker: TUniMapMarker);
begin
  with Marker do
  begin
    Popup.content:='A New Marker';
    AddToMap;
    OpenPopup;
  end;
end;

I not see the way to access to the markers that I had created before.

I try to explain again, I want to show, to see, to display all the markers that I had created into the map before.

I don't know how to display the markers created before when I open the application.

How can I do that?

Thanks.

Hello

You should have latitude and longitude of markers.

Please use onMapReady event and add them in to map.
