ArcGIS Mobile 10 for WPF - Annotation Layer

[DavidBeni]

Hello everyone,

I search a solution for this problem since several days, and my first conclusion is that is not possible...
But if someone meet this problem and got a solution ?

I work with the ArcGIS Mobile 10 API for WPF, and i want to add a part of my annotation layer in my map.

I've got a MobileCache Object, set with ArcGIS Server.

public MobileCache LocalMobileCache { get; set; }

Then I asked this cache to retrieve an annotation layer, called "Annotation".

var annotationLayer = (from f in LocalMobileCache.FeatureLayers
                             where f.Name == "Annotation"
                             select f).FirstOrDefault() as AnnotationLayer;

Next, I want to retrieve only a certain portion of these data and displaying it on my card.

QueryFilter filter = new QueryFilter();
filter.WhereClause = "Request???";
using (FeatureDataReader reader = annotationLayer.GetDataReader(filter, null))
{
    while (reader.Read())
    {
        //How to get here the annotation and display it on the map ?
    }
}

With this solution, I can collect the information I need with the request, but I can't display it on the map. The geometry of the reader look like a rectangle...

Is it possible with the ArcGIS Mobile 10 API for WPF ?

Thanks in advance.
