Is the identify function not possible in the version 100

Pierre-JeanMuller

I tried to do an identify 

var task = MainMapView.IdentifyLayerAsync(srtmValueLayer, e.GetPosition(MainMapView), 0,false ,1);

I get this error in the task result of the task :

Error = {"Invalid argument: Identify parameters do not specify a region in the view extent."}

According to the list that shows the implemented functionalities in the version 100:

Choosing the right version | ArcGIS for Developers 

The ImageServiceLayer is not implemented. So do I have to change to the version 10.2.7 in order to have an identify function?

This should work in v100. What event are you using and what's e.GetPosition(MainMapView)'s value when you get this error? 

<SPAN class="keyword token">var</SPAN> position <SPAN class="operator token">=</SPAN> e<SPAN class="punctuation token">.</SPAN><SPAN class="token function">GetPosition</SPAN><SPAN class="punctuation token">(</SPAN>MainMapView<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN>

You can also try the following code. Using GeoViewTapped, you can pass either specific layer or identify all layers. In the identified result, notice that ArcGISMapImageLayer have results in SublayerResults and FeatureLayer have results in GeoElements.
