@John_Codd_LearnThenShare Sound like you are needing this link then. https://doc.arcgis.com/en/web-appbuilder/10.9.1/create-apps/add-custom-widgets.htm

Jay, You are on the right tract with the distance and unit stuff. A far as querying the buffer graphic. Just get the graphic from the bufferGraLayer graphics property. let buffGeom = bufferGraLayer.graphics[0].geometry; Or just keep a global var of the buffGeom in your app from the BufferGeom function.

So this is the response I get from my web service {"suggestions":["123","1231","1232","1233","1234","1235","1236","1237","1238","1239","12333","12334","12335","12335","12336","12337","12339","12340","12341","12342","12343","12344","12345","12346","12347","12348","12349"]} And yours is: [{"texto":"Arroio Areal"},{"texto":"Arroio Arenal"},{"texto":"Arroio Baje"},{"texto":"Arroio Bolacha"},{"texto":"Arroio Candiota"},{"texto":"Arroio Caracá"},{"texto":"Arroio Castelhano"},{"texto":"Arroio Cavera"},{"texto":"Arroio Chico Loma"},{"texto":"Arroio Chuí"},{"texto":"Arroio da Pintada"},{"texto":"Arroio das Lavras"},{"texto":"Arroio Del Rei"},{"texto":"Arroio Do Bote"},{"texto":"Arroio dos Ratos"},{"texto":"Arroio Francisco Alves"},{"texto":"Arroio Garupa"},{"texto":"Arroio Grande"},{"texto":"Arroio Ibacuru"},{"texto":"Arroio Ibirocai"},{"texto":"Arroio Jacaré"},{"texto":"Arroio Jaguarão-Chico"},{"texto":"Arroio João Dias"},{"texto":"Arroio Não Sabia"},{"texto":"Arroio Pelotas"},{"texto":"Arroio Pequiri"},{"texto":"Arroio Petim"},{"texto":"Arroio Pinhal"},{"texto":"Arroio Pirai"},{"texto":"Arroio Portão"},{"texto":"Arroio Ribeiro"},{"texto":"Arroio Ribeiro Pequeno"},{"texto":"Arroio Saicã"},{"texto":"Arroio São Lourenço"},{"texto":"Arroio Sutil"},{"texto":"Arroio Taquara"},{"texto":"Arroio Taquarembozinho"},{"texto":"Arroio Telho"},{"texto":"Arroio Vacaquá"},{"texto":"Arroio Velhaco"},{"texto":"Arroio Vira Carreta"},{"texto":"Lagoa dos Barros"},{"texto":"Rio Carreiro"}] The BIG difference is you are returning an array of objects and mine is returning an object that has a property containing an array of strings... So in the def.then of my code I am doing array.map(resp.suggestions, lang.hitch(this, function(val){ iterating through the resp.suggestions (where resp is an object and suggestions is a property of that object and is an array). In your case it would be more like: array.map(resp, lang.hitch(this, function(val){
var item = new MenuItem({
label: val.texto,
onClick: lang.hitch(this, function (evt) {

So are you saying that in the Suggest_TextBox.js code you are getting the results you would expect from your C# web service inside the def.then portion of the _popup function? I do not see 'arr' variable in the code I provided so I am a little confused.

@VictoriaJadot So I just did some testing in a web scene and had no issues using this widget when the clicked layer has a popup enabled/configured (and buildings are highlighted). I can see from your image that you still have the scene views popup enabled (and it shows not fields, so that leads me to wonder if your buildings layer has popups configured). In this widgets settings you are cautioned to disable the views popups unless you want the views popup on the map and this widgets panel to show the same data.

@JamesFaron There seems to be some issue right now downloading apps from 1.9. So I have patched 1.7 version of this widget. I did test these same changes in EB 1.9 and it works, but I just cannot download the 1.9 version app of this widget.

@JohnCodd Custom widgets have two options WAB Dev deployed on your own web server, and ArcGIS Enterprise (Portal) that your organization has deployed. If you are working with just AGOL WAB then you are out of luck.
