Detemine if FeatureLayer is visible in current extent.

Question

Hi,

I have subscribed to the map extent changed event.I want to check if my feature layer is visible or not in this extent.

How could I do that? I looked into the FeatureLayer members and could not find any thing that would indicate its visibility.

Any help is appreciated.

Somehow I overlooked this visible property of the FeatureLayer.It should solve my issue now.
Appreciate your help.

It looks like I have to use Layer base class and use its visible property.

Each instance of FeatureLayer does indeed have a visible property.
Since FeatureLayer is added to map, its extent would always intersect map's extent.So, how extent intersection is gonna work for me?Please correct me if I am wrong.

Why would a FeatureLayer's extent always intersect the map's current extent?

About extent stuff. Since FeatureLayer is added to map, its extent would always intersect map's extent.So, how extent intersection is gonna work for me?Please correct me if I am wrong.Do not mind but I am very much new to this API.I find it very difficult to program with this API.You know, things are easy with SL api.
