Hi Katherine,
Thanks for your answer! But I did as you said but the features are still not saved.
Now there is one more problem I want to need your help.
At the time I create this thread, when I add the feature layers in my feature service to the "Map contents" in my ArcGIS Map Web Part, then I navigate to the "Add Features" and in this panel there are feature templates of the added feature layer so that I can draw these features on the map.
However, now I cannot do that anymore. When I repeat the process of adding feature layers in my feature service to the map, I don't see any feature templates in the "Add Features" anymore, therefore I cannot draw these features on the map.
I have created many different feature service hosted on the ArcGIS Online. And no one in these feature services can provide me capability to draw features on the ArcGIS Map Web Part.
It's strange that, the first time I did add a feature service to the ArcGIS Map Web Part, I can draw features on the map (but the features are not saved)
And now I even cannot draw features on the map (because there is no feature template in the "Add Features")
I would appreciate if my problems are solved.
