Feature layers don't display on the map (WPF Application)

deleted-user-i8mW0s-ySag1 — Thu, 16 Oct 2014 10:05:07 GMT

With the release of ArcGIS Runtime SDK 10.2.4, I've read the developer's guide and tried to do the various tutorials.

But I have a problem with the part "Add a feature layer to provide operational data" (https://developers.arcgis.com/net/desktop/guide/access-feature-data-in-the-cloud.htm).

When I add a feature layer on the base map, it doesn't display at all, no matter how I try (by XAML or by code). I even used the layer.InitializationException to check if it was correctly loaded. All I can see is the basemap without the swimming pool permits layer.

For your informations, I'm working with Visual Studio 2013 Express Edition.

Can you please help me to find what I'm doing wrong?

Thanks in advance for your answers.

Here's the code I use for my basic project (WPF Application in Visual Basic):

Looks like the PoolPermit feature server<http://sampleserver6.arcgisonline.com/arcgis/rest/services/PoolPermits/FeatureServer> is no longer working well.

Even the arcgis.com viewer<http://www.arcgis.com/home/webmap/viewer.html?url=http%3A%2F%2Fsampleserver6.arcgisonline.com%2Farcgis%2Frest%2Fservices%2FPoolPermits%2FFeatureServer&source=sd> is not able to display the features.

Error returned by the server:

{"error":{"code":500,"message":"Error performing query operation","details":[]}}

Indeed, you're right, thanks. But the PoolPermit feature service was working yesterday! I was able to open it directly in arcgis.com.

Homever, my problem remains. I've tried to create an application with internal datas using an

ArcGISDynamicMapServiceLayer and a FeatureLayer (like the example). The first was visible but not the second. And I could see all my features with the ArcGIS.com Map viewer.

Does Spatial References match with MapView and FeatureLayer?

For the ESRI example, I suppose (that's the goal of a tutorial). Regarding my local datas, the 2 layers are in the same coordinate system, yes.

PoolPermit service is up again. I tested your code and it seems working.

Could you try again?

If you are experiencing issue with another services, please share your code so we can reproduce the issue.

Thanks.

Thank you for your help.

Indeed, The PoolPermit is up again. But my code still doesn't work on my side. For your information, I've created a WPF application (Visual Basic) in Visual Studio Express 2013 (my test platform is on Windows 7). I've pasted my code in the MainWindow.xaml and this is the result I get:

Could it be a problem with the Visual "Express" edition? Or with some parameters of the solution? (I've left everything by default) I've also tried a WPF application in C# with the same result.

Have you checked if there is any errors when layer is loaded? You can access to that from MapView.LayerLoaded event.

Also could you check what data is fetched from the server using Fiddler etc.

Thank you for your tips.

I've tried the mapView.LayerLoaded event and the PoolPermits layer was loaded successfully.

And here's a screenshot of the traffic data through Fiddler:

Everything seems allright.

I've opened the tiles under the FeatureServer (in Fiddler) and there isn't any pool drawed on the map (only the base map).

Here's the complete url sent:

What was the response from the server?

I tried the code that you posted in the original post and it seems to work for me. Going to test that in express edition but need to install it first.

Just for kicks, can you try to set CultureInfo to en-US or GB and see if that helps. I assume that you are using some other. Or can you let me know what you are using?

Tested with VB.NET and Express edition of VS. Also tried with "fr-CH" but cannot find any issues.

Can you zip your project and send it directly to me (see email from profile)?

Sorry, but I cannot find your email under your profile, nor in your vcard.

But you can access my project here:

Microsoft OneDrive

oh, need to check that.

Tried your zip and it works for me. You were using Win7?

deleted-user-i8mW0s-ySag1 — Fri, 17 Oct 2014 10:09:34 GMT

It worked? Very strange. Yes I'm on Win7 with the SDK 10.2.4. I'll try on another desktop this afternoon and write you back.

Thanks for your tests.

I've done a fresh install of Visual Studio 2013 Express with the ArcGIS Runtime 10.2.4 on another Win7 platform and It worked!

The only "major" difference between the two is that I had the Runtime 10.2.3 Beta on my Desktop before. Could it be a part of the problem?

Good to hear that you have managed to solve that issue. It shouldn't affect but it's good practice to remove all references to Beta SDK before installing RTM.

I have run into the same issue, it quite weird.

Still don't know how to fix it.

wpf application, Windows 8.1, visual studio 2013 ultimate, arcgis runtime sdk 10.2.4 (or 10.2.5)

feature layer not displaying.

Does the query towards the service return correct features? Is there any initialization errors on FeatureLayer / ServiceFeatureTable? Is there any errors in ServiceFeatureTable's Updated event?
