How to make the graphic of featurelayer invisible?

[TengJiang]

I have encountered a problem. I want to control the graphic visbile/invisible, but I found it can't wok when the graphic is from featurelayer. The featurelayer is from feature service. So is there some solutions?

both not work.

Thanks

Does anyone have any idea? I use FeaturelayerView.filter to realize the effect, but I don't make sure if it is the best way.
