Creating Popup Definition

HS_PolkGIS — Thu, 07 Nov 2024 16:41:50 GMT

I have a simple Identify Layer tool, that should be displaying information in a popupviewer, however only the Title is being displayed in the PopupViewer Control.

Simplified example is below after following the Configure Clusters sample.

I have tried creating a PopupDefinition in numerous ways but the only thing that displays in the popupviewer is the Title. The rest remains blank. I have to be missing something.

Xaml

<esri:PopupViewer x:Name="popupViewer" Margin="5" Width="375" MaxHeight="400"/>

Xaml.cs

private async void PolkMapView_GeoViewTapped(object sender, Esri.ArcGISRuntime.UI.Controls.GeoViewInputEventArgs e) { //Hardcoded the Specific Layer FeatureLayer _layer = (FeatureLayer)_mapView.Map.OperationalLayers[27] ?? new FeatureLayer(); var results = await _mapView.IdentifyLayerAsync(_layer, e.Position, 3, true); //Resulting Pop is NOT Null and HAS a PopupDefinition with Fields var p = results.Popups.First(); if (p != null) { popupViewer.Popup = p; popupViewer.Visibility = System.Windows.Visibility.Visible; Console.WriteLine("Title " + p.Title.ToString() + " Field count: " + p.PopupDefinition.Fields.Count()); } }

PopupDefinition (Feature Layer is loaded from a .geodatabase file; Renderer and Label Definitions are created along with the PopupDefinition - only the popup is having issues)

parcelPolyLayer.IsPopupEnabled = true; PopupDefinition newP = new PopupDefinition() { Title = "My Custom Title"}; PopupField newF = new PopupField() { Label = "Strap", FieldName = "JOIN_STRAP", IsEditable = true, IsVisible = true, StringFieldOption = PopupStringFieldOption.SingleLine }; newP.Fields.Add(newF); parcelPolyLayer.PopupDefinition = newP;

Hi @HS_PolkGIS,

I've managed to reproduce the issue you're seeing.

I'm going to check to see if there is another way to achieve this and get back to you.

Thanks for your question.

Could you try setting height instead of the maxheight? I wonder if it is rendering, but just not sizing itself right.

That would have been a nice easy fix but unfortunately, still the same except a bigger popup.

<esri:PopupViewer x:Name="popupViewer" Margin="5" Width="375" Height="250" MaxHeight="400" />

Thanks for confirming. On second look I realize you're adding to Fields and not Elements.
Try this instead:

PopupDefinition newP = new PopupDefinition() { Title = "My Custom Title" };
PopupField newF = new PopupField() { Label = "Strap", FieldName = "JOIN_STRAP", IsEditable = true, IsVisible = true, StringFieldOption = PopupStringFieldOption.SingleLine };
newP.Elements.Add(new TextPopupElement("This is just some <b>generic text</b> you can add"));
newP.Elements.Add(new FieldsPopupElement(new[] { newF }) { Title = "Attributes" });

Making a little progress.

All of the "static" text is appearing in the Popup but I am getting binding errors. All the original code is the same but I used the suggested TextPopupElements and the FieldsPopupElement lines... Adding a AttachmentsPopupElement with displaytype of list did not resolve anything.

The first error happens on app loading and the 2nd happens when the popup is set in the geotapped event. The error seems to be expecting an AttachmentsPopupElement and not the FieldsPopupElement.

Is the JOIN_STRAP field name correct? Did you make sure the feature you got is fully loaded and has that attribute in it?

You can ignore the binding errors for now

The field name is correct, and I did try a few other fields, including surrounding with [brackets]. I added screenshots while stepping through in case you can see anything.

Fields in the Table and Attributes on the Layer. Then the FieldPopupElement which has the single field item - newF.

Also included how the Table and FeatureLayer are loaded and the exact code used to create the definition.

Thank you for the help on this.

Geodatabase? parcelsDb = LoadGeodatabase(localPath); parcelsTable = parcelsDb.GetGeodatabaseFeatureTable("SVA_MGIS"); var parcelPolyLayer = new FeatureLayer(parcelsTable); parcelPolyLayer.LoadAsync().Wait(); parcelPolyLayer.IsPopupEnabled = true; PopupDefinition newP = new PopupDefinition() { Title = "My Custom Title" }; PopupField newF = new PopupField() { Label = "Strap", FieldName = "JOIN_STRAP", IsEditable = true, IsVisible = true, StringFieldOption = PopupStringFieldOption.SingleLine }; newP.Elements.Add(new TextPopupElement("This is just some <b>generic text</b> you can add")); newP.Elements.Add(new FieldsPopupElement(new[] { newF }) { Title = "Attributes" }); parcelPolyLayer.PopupDefinition = newP; //Layer is then added to Map.OperationalLayers

> Also included how the Table and FeatureLayer are loaded

I was referring to the feature itself. Try adding (feature as ILoadable)?.LoadAsync(); before assigning it to the popup. Also assert that the feature itself does have that attribute populated.
Lastly set a breakpoint on the Popup that is returned from identify, call "await Popup.EvaluateExpressionsAsync()" and inspect "EvaluatedElements" and verify the fields are present

Re: Creating Popup Definition

HS_PolkGIS — Fri, 08 Nov 2024 16:59:45 GMT

Added the LoadAsync, doesn't appear to make a difference, and EvaluatedElements to the GeoTapped Event.

I can see the 2 evaluated elements, text and field, both have the properties set as expected.

I can even see the correct value when looking at the FormattedValue...But still only the Titles and text field are displaying in the popup.

//Added LoadAsync but nothing changes with/without await _layer.LoadAsync(); var results = await PolkMapView.IdentifyLayerAsync(_layer, e.Position, 3, true); //The FormattedValue is Correct when looking at the EvaluatedElement var p = results.Popups.First(); await p.EvaluateExpressionsAsync(); var evalElements = p.EvaluatedElements; popupViewer.Popup = p;

Hmm that all looks good. I haven't been able to reproduce that behavior. Is there any chance you could share a small sample that reproduces the issue using some public data?

Re: Creating Popup Definition

HamishDuff — Mon, 11 Nov 2024 15:27:42 GMT

@HS_PolkGIS my problem was addressed by adding the line:

newP.Elements.Add(new FieldsPopupElement(new[] { newF }) { Title = "Attributes" });

Are you still having issues?

Re: Creating Popup Definition

HS_PolkGIS — Tue, 12 Nov 2024 13:14:45 GMT

I am looking into getting a public set to provide here.

If it helps, this project is for a conversion from old ArcReader map that was using .gdb files to a map package using .geodatabase file as the source.

Our use of the popup is limited to one feature, so we might simply make a custom display and move on for now.

Re: Creating Popup Definition

HS_PolkGIS — Tue, 12 Nov 2024 13:32:13 GMT

Yes, after adding that line the popup still only displays the Titles and static Text Field elements. The popup definition does have the correct evaluated field values which can be seen stepping through code.

Re: Creating Popup Definition

HamishDuff — Tue, 12 Nov 2024 16:35:47 GMT

I see in another response you've mentioned looking into providing a public set of data for us to try to reproduce your issue with.

If you are able to do that it would be helpful as I'm unable to reproduce the issue here.

Re: Creating Popup Definition

StreeterRobert — Tue, 22 Jul 2025 22:00:19 GMT

Wondering if there was a resolution to this issue. I am running into the same problem. Popup is only displaying the value of the first field of type text in the attribute table.

Stepping through the code in Visual Studio indicates all expected field names and values are present on the popup's EvaluatedElements property.

Since we haven't been able to reproduce, there hasn't been any progress. If you have a reproducer you can share, I'll be more than happy to take a look.
