Maptips - Is there a feature count limitation?

BrandonIves — Thu, 12 Aug 2010 12:14:09 GMT

I have a map with some water utility data. I have a feature mousetip come up on mouseover event. In my mxd I have a feature class with about 27,000 features. When I run my app through VS2008 I only get 500 of the features to symbolize with the default red point dot. Is there a limitation to the amount of features?

I know that 500 came up because I added a clusterer to see the total count at full extent.

Also is there a way to turn off the default point symbology for the maptip? I would rather there not be a point or outline for the feature class I am using. Is there maybe a way to have no color on the symbol?

Thanks

Also I was looking at the ESRI samples (http://resources.esri.com/help/9.3/arcgisserver/apis/silverlight/samples/start.htm) and noticed that all their samples have less than 500 features. The max I saw was 305 in the example for features.

The service may have reached its limit of how many features it can return at once (the default is 500 for ArcGIS Server 9.3.1, 1000 for ArcGIS Server 10, 1000 for MapIt)... as mentioned here:http://help.arcgis.com/en/webapi/silverlight/help/creating_featurelayer.htm

You can set the FeatureLayer.Symbol property depending on the geometry type (Marker symbols for Points, Line symbols for Polylines, Fill symbols for Polygons) or apply a renderer to FeatureLayer.Renderer. Either these properties can be set with any symbol of your choosing as long as it makes sense (matching the geometry type).

Check out our Symbol Gallery, Renderer and Custom Symbol samples:
This is for API v2.0 http://help.arcgis.com/en/webapi/silverlight/samples/start.htm
and API v1.2

Thanks for the quick response.

Is the mode property only available in API 2.0? I am on API 1.2 and mode is not available.
