HI,

 

We are developing the app. where user can draw object on map and want to save the location and map extent with all drawn graphics on it to the our server using some serialize JSON representation of that state. and when user come afterward by clicking location Item we want to re-render same state with all last graphics we had drawn on it using same serialize JSON object from server. how to achieve this feature in ArcGIS javascript API. do we need to write our own feature layer if yes then how to do it?
