Remove graphics layer doesn't work

LeLuong — Thu, 14 Oct 2021 22:12:24 GMT

All,

I'm trying to remove the graphics layer on map. Codes did go through

graphicsLayer.RemoveElements(graphicsLayer.GetSelectedElements());

but nothing happened. My graphics layer is still there. Am I missing something?

protected async override void OnClick() { //Get the graphics layer var graphicsLayer = MapView.Active.Map.GetLayersAsFlattenedList().OfType<GraphicsLayer>().FirstOrDefault(); await QueuedTask.Run(() => { //Remove existing graphicsLayer if (graphicsLayer != null) { graphicsLayer.RemoveElements(graphicsLayer.GetSelectedElements()); } });

Thanks!

Hi,

Your code removes selected elements of graphics layer. To remove graphics layer you need to remove map layer using QueuedTask.Run like this :

MapView.Active.Map.RemoveLayer(graphicsLayer);

Thank you very much @GKmieliauskas . I actually wanted to remove all elements. I should use

graphicsLayer.RemoveElements(graphicsLayer.GetElements()); instead of

graphicsLayer.RemoveElements(graphicsLayer.GetSelectedElements());
