Using PopUp to display FeatureLayer information with Xamarin.Forms

ThomasVercoutre

I am trying to display information from a feature layer using PopUp.

I am using the Esri.ArcGISRuntime.Xamarin.Forms nuget package.

I saw that you can specifiy a PopupDefinition on the FeatureLayer but how to display information on the MapView.

I'd like to open a popup when a user click on a feature but did not find any sample.

Any idea ?

Cheers

I also spent hours in search for sample code to display pop-up on the MapViewer. It seems to me this is a very fundamental and essential function of the MapViwer. Hopefully ESRI can quickly put up sample for how to display pop-up that already defined in a webmap and layer for a MapViewer.

Agree: the SDK is great!

Thanks,

Thanks, but how do I display the pop-up ? I don't need to get the pop-up to iterate through the attributes (I can just query the feature).

To get to the popup on all/any layers for a tapped location , you will have to call MapView.IdentifyLayersAsync(),or you can call MapView.IdentifyLayerAsync to get info for a specific layer. The result of Identify "IdentifyLayerResult" has Popups property that will return popup info on a layer(s).

Side note, if layer has sublayers then you would need to get the SublayerResults and then check for popups for that sublayer.

Just to give an idea I quickly typed following code to demonstrate how to get the popup from a featurelayer. This is not a functional code. Let me know if you still have problems and I will put together a quick sample.

IReadOnlyList<IdentifyLayerResult> results = await MyMapView.IdentifyLayersAsync(Position, tolerance, false,Features);

foreach (IdentifyLayerResult identifyLayerResult in results)

{

if (identifyLayerResult.Error != null)

{

//Display error

}

else if (identifyLayerResult.Popups?.Count > 0)

{

//Get the popup for geoelement

var ge=identifyLayerResult.Popups[0].GeoElement;

//get attributes

foreach (KeyValuePair<string, object> element in ge.Attributes)

{

// do something

}

else if (identifyLayerResult.SublayerResults?.Count > 0)

{

foreach (var sublayer in identifyLayerResult.SublayerResults)

{

if (sublayer.Popups?.Count > 0)

{

////Get the popup from sublayer

var sublayerGE=(sr.Popups[0].GeoElement);

}

....

}

Sorry did not find any solution for the moment. Not sure if pop up is supported for the moment

Did you end up finding a solution to this? I am having a similar issue.
