Webapp- Show points within a selected polygon

RickeyFight

I have over 3 million points. I cannot have my server displaying all these points on a map a the same time.

What I want to do is when a building is selected, show all points within that polygon.

I know about this example:

Select with Feature Layer | ArcGIS API for JavaScript

I am not sure that will work because I don't want a buffer I want to use another Layer.

Thank you

Yep you can use the same idea as the sample you linked to but instead of using a buffer you'll just use the geometry of the other layer. Here's an example that selects all the points within a census block group.

Select with feature layer

If you look at the code you'll see that we setup a click handler for the block feature layer and when its clicked we query the point feature layer using the clicked geometry.
