Hi,
I have a feature layer with like 20,000 features, and one of my requirements is to change the color of the feature upon user selection. I tried to do this by simply changing the PointStyle that's used to render the feature in the same feature layer, which requires a refresh.
The amount of time it takes for the refresh to occur upon user selection is too long, so I have some design questions.
Would it perform better if I created a separate layer for rendering the selected features?
Is there any way to invalidate a small region of the screen?
Thanks,
Greg
