Change Visibility of Features in a Layer by Query?

[UlfGrimhardt]

Hi

i have a Silverlight-App with one ArcGISDynamicMapServiceLayer that consists of two sublayers.
The sublayer show Point and Line features.
Now i need to highlight specific features by a findquery. But instead of just highlighting the features it would be the best if only those queryied features would be visible and the other point-features would disappear.

Is this possible? To change the visibility of specific features in a layer? I know i can do this in ArcMap via QueryManager in the Layer Options. But is it possible in Silverlight?

You can use the LayerDefinitions property for this: http://help.arcgis.com/en/webapi/silverlight/apiref/ESRI.ArcGIS.Client~ESRI.ArcGIS.Client.ArcGISDyna...
