I find a bypass solution in creating a point which intercept my layer and return the feature attributes values in a rowcollection.
here is the code :
'requete pour afficher les enregistrements issus d'un intersection avec un point ou un polygone
Dim layer As FeatureLayer = TryCast(ESRI.ArcGISExplorer.Application.Application.SelectedItems(0), FeatureLayer)
' allow the user to digitize a point on the map
Dim point1 As ESRI.ArcGISExplorer.Geometry.Point = ESRI.ArcGISExplorer.Application.Application.ActiveMapDisplay.TrackPoint()
Try
' query the feature layer for the features that intersect the point
Dim rowCollection As RowCollection = layer.Table.Search(New Filter(point1, FilterSearchOptions.Intersects))
Dim elt As Row = rowCollection.ElementAt(0)
Dim numprop As String = elt.Values(10)
MsgBox(numprop)
Catch ex As NullReferenceException
System.Windows.Forms.MessageBox.Show("No features were selected. Please try again.")
End Try
