Hi,
I'm using esri ArcGIS JavaScript API V3.22 for our product and I'm trying to get the cost time for a graphics layer rendering after pan / zoom the map.
I take a scripts and could not fire the events of 'update-start' and 'update-end' for a GraphicsLayer.
How to fire these events on GraphicsLayer?
Thanks,
Leo
