QueryTask Issue

[Anonymous User]

Original User: tgorrie

QueryTask does not select features directly beneath the input geometry (polyline), only those that cross it. Features from both input and selection layers come from the same data source layer so they should match geometrically. I have tried all spatial relationships (touches, intersect, etc) none work. If I use the extent geometry (polygon) then the query works but I get too many other unwanted records in the result.

I have also tried the same spatial query in ArcGIS desktop and it works correctly.

Any thoughts?

Thanks.

Have you tried using Editor's Select command? You can set SelectionMode to Polyline.
You can refer to this sample: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#FeatureLayerSelection
