FeatureLayer missing features at full extent.

Question

I have an dynamic layer in an msd. Its the only layer in the msd. When the map first comes up at Full Extent only some of the features display. As so: If I change it to a ArcGISDynamicMapServiceLayer if works. As so: Whats wrong? I need a feature class because I need the "Where" method. 9.3.1 SDE Desktop, ArcGIS Server GIS - Web Application, ArcGIS Server - GIS Services are all on 10 sp 1

You are right, when using FeatureLayer Snapshot mode (default), 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 and 1000 for ArcGIS Server 10, but this limit is configurable using the Parameters tab of the Service Properties dialog box in ArcCatalog or Manager. This seems to be a related thread: http://forums.arcgis.com/threads/19467-Query-Task-only-returns-500-records-even-after-changing-MaxRecordCount-to-3000-in-cfg

Here's an example of using LayerDefinitions: http://help.arcgis.com/en/webapi/silverlight/apiref/ESRI.ArcGIS.Client~ESRI.ArcGIS.Client.ArcGISDynamicMapServiceLayer~LayerDefinitions.html

Its just missing alot of features when I use the featurelayer.

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). 
In this case, try with the OnDemand mode (see sample).
 How do you set the layer definition on the ArcGISDynamicMapServiceLayer? What method? Do you have an simple code example?

I don't think there is a sample in the interactive SDK, but the documentation about the 'LayerDefinitions' should be very helpful : http://help.arcgis.com/en/webapi/silverlight/apiref/ESRI.ArcGIS.Client~ESRI.ArcGIS.Client.ArcGISDynamicMapServiceLayer~LayerDefinitions.html
