Highlight on FeatureLayer

PaoloF — Thu, 09 Sep 2021 10:23:17 GMT

Hi everyone into Community.

I have an Angular application where I load portalID item derivede from DXF file as FeatureLayer and I highlight layer polygons according to selection.

I woud like to dinamically change color before highlighting the resulting feature, but setting it in highlightOptions of the mapView doesn't affet the result.

The following is the code I wrote:

public highlight(filter: string) { console.log(this.mapView.highlightOptions.color); this.mapView.highlightOptions.color = new Color('green'); console.log(this.mapView.highlightOptions.color); this.mapView.whenLayerView(this.featureLayer).then((layerView) => { const query: Query = new Query(); query.returnGeometry = true; query.outFields = ['*']; query.where = "Text='" + filter + "'"; this.featureLayer.queryFeatures(query).then((result) => { if (this.highlightState) { this.highlightState.remove(); } console.log(this.mapView.highlightOptions.color); this.highlightState = layerView.highlight(result.features) as Handle; }); }); }

As you can see, I added console.log instruction to check the setting when I call the function and I try to change its value: during execution when I enter first time into the function I see that setting is initialized as made in mapView definition (RED), it's correctly modified to GREEN, but the highlight item is always shown in RED.
When I call again the function, the setting is GREEN from the beginning, but highlight is in RED.

May any of you explain what I'm doing wrong?
Thanks in advance, best regards.

Hi everyone.

I solved by myself the issue I post this morning in following way:

this.mapView.set('highlightOptions', { color });

where color is a string variable containing the color I desire to show.
