THank you. It seems that Chrome and Edge cannot render the whole page. If you scroll down you will see that it cuts off . Firefox can display the whole code but it displays it in one line :(. So, I have to manually to insert the line breaks to make it readable.  ESRI is aware of the issue and they are looking into it. THanks. ... View more

Hi Robert. The solution you posted at https://community.esri.com/t5/arcgis-api-for-javascript-questions/does-the-class-quot-esri-toolbars-navigation-quot/td-p/567061 cannot be rendered in its whole. There are issues with the ESRI website and it can't display the whole solution. Can you please post it again? Thanks. ... View more

It sounds like you need to create a custom simple widget with a button which calls a geo service on onclick. ... View more

Yes, off course it is possible. You have to make your custom widget to start  at the  startup. See Config.js of the app below. Then write the Js to act as soon as the user enter the code in the widget to perform the query. "widgets": [{ "uri": "widgets/YourWidget/Widget", "id": "YourWidget", "IsController": false, "name": "YourWidget", "openAtStart": true },   ... View more

I don't know how comfortable you are with JS but I changed the code on the screening widget to not require a layer to be selected before you create a map. Or you can create a custom widget to do that. Here is some code that I used to create custom buffer.     mysymbol = new SimpleFillSymbol(SimpleFillSymbol.STYLE_NONE, new SimpleLineSymbol(SimpleLineSymbol.STYLE_DASHDOT, new Color([255, 0, 0]), 2), new Color([255, 255, 0, 0.25])); geodesicBuffer.distances = [thebufferdistance]; geodesicBuffer.unit = bufferunit; geodesicBuffer.outSpatialReference = this.map.spatialReference; geodesicBuffer.geodesic = true; geodesicBuffer.unionResults = true; bufferGraphicsLayer = new GraphicsLayer(); esriConfig.defaults.geometryService.buffer(geodesicBuffer, lang.hitch(this, function (evt) { resultEvent = evt[0]; var geodesicUserGraphic = new Graphic(); geodesicUserGraphic.setAttributes({ "name": "Buffer" }); geodesicUserGraphic.geometry = resultEvent; geodesicUserGraphic.symbol = mysymbol; bufferGraphicsLayer.add(geodesicUserGraphic); this.map.addLayer(bufferGraphicsLayer);     ...

THat what the screening tool does. You select which graphic you want want to buffer around (in your case, point) then define the distance to buffer around.  ... View more

The screening tool does buffer as well and you can print a report about the features are within the buffer zone. No spatial analysis or other licenses are required. ... View more

Robert, in my case the features are added through custom code. I have done so many times with no issues. This time the filter, Zoom to, Clear Selection tools are disabled and cannot select an individual row. This time, I didn't specify a unique id. The features are defined by:   thegraphic.setAttributes({ "Label": label, "Param1": param1, "Param2": param2, ---------------- })     ... View more

I had a similar need. I just created a feature layer with the queried features and add to the map. The AT will show that layer under a new tab and list only the queried features. ... View more

I personally didn't print any AT from the print widget. Just export to the csv and then print it from there (notepad or excel). ... View more

I came across the same issue a while ago, and I posted this solution. https://community.esri.com/t5/web-appbuilder-custom-widgets/export-to-csv-from-a-featurelayer-with-no-url/m-p/846221 ... View more

For a custom widget, I found it a lot easier to use one of the bare bones widgets that are under the samplewidgets folder located at "<WAB location>\client\stemapp\widgets\samplewidgets". You can modify one these widgets with your code. Then, you can add it in the widgets folder of your app and add an entry in the app's config.json. For other completed widgets like the ElevationProfile, you can  either edit the WAB app or manually add the widget in the widget folder the same way you can do for a custom widget as I described earlier.   ...

I don't know what is your level of JS experience but here is a post for the same issue. You can use the same script to select a layer to be visible or not. https://community.esri.com/t5/web-appbuilder-custom-widgets/make-layer-visible-after-layerlist-widget-has-opened/td-p/846584 ... View more

Standalone. No, this the first time I am trying this script from: https://enterprise.arcgis.com/en/server/latest/administer/windows/backup-utility.htm ... View more
