OnDemand mode (online)

Explore a feature layer that is in OnDemand mode. In OnDemand mode, only features within the current map extent are retrieved. As the map extent changes, additional features are requested for the newly visible areas. The service enforces a maximum number of features returned per query. The red points in the map are the active features from the Block Point feature layer. The blue points in the map are those graphics from the Census dynamic layer. Blue points are visible only when the feature layer has returned the maximum number of features it can and there is no red point available to overlay the blue point. Pan to a new area to activate the features in that extent. Zoom out about three levels (three mouse wheel clicks or press the down arrow key three times) and notice that blue points appear from the dynamic layer. The feature layer has returned its maximum number of records. Zoom in and notice that red points replace some blue points when mouse is released. Click an active feature to view attributes of that feature.
