What is the best way to lazy load a feature layer for a map? In my application, I have a map and handful of layers, some are turned off by default on launch. These feature service layers that are off by default I would like to delay loading until the user clicks that layer's on/off check box. Is this possible within the ArcGIS Online JS API? The solution I've brainstormed so far is to set the layer's url to an empty feature service when the layer is first instantiated. Inside the checkBox.on("change") function I would change the url to the correct feature service url, refresh() the layer, then proceed with the rest of the code that handles the layer rendering and tables. I don't want to reinvent the wheel when possible, so I'm looking for a documented or better way of handling this while I roll my own solution.

Thanks for the reply, this is an interesting implementation of a testLayer() function. I'm giving this a try in my application right now!

Thanks for the helpful reply - I've implemented something similar and this appears to be what I need.

The web app, web map (and all the feature layers I created and included in the map) are set to share publicly.

Before I load and begin querying all the feature service layers in my map that I have created with the ArcGIS JavaScript API, I would like to first verify that the service is responding. What I'm trying to accomplish is to check if any urls are not responding, and if so, skip those feature services and allow my application to keep loading without them. What is the best/recommended way to do this?

Unfortunately I do not have access to Esri tech support as this is for a personal project using the free version of AGOL. I'm stumped by this because it worked fine for months up until Wednesday, then all of the sudden the errors started appearing. I had made no changes to the web app or map recently.

I'm currently attempting to embed a web app into my page. The web app is hosted in ArcGIS Online (not my organization's portal).

I did. Maybe I'm misinterpreting things, but isn't the X-Frame-Options header something that is set on Esri's side? I'm not hosting the web map, Esri is - I'm just using the html that is generated when I click "share" on my web map. I don't see any mention of X-Frame-Options headers in this help page: Embed maps, apps, and groups—ArcGIS Online Help

I'm also having this issue. All of the sudden today Chrome and Firefox and IE will not display my embedded web app on a web page, giving me the "Refused to display 'https://www.arcgis.com/home/signin.html?returnUrl=http%3A//www.arcgis.com/apps/View/index.html%3Fappid%...' in a frame because it set 'X-Frame-Options' to 'deny'."

Today I've started getting this error message when attempting to view my we bpage which contains an embedded AGOL web app in an iframe: <iframe style="height: 90vh" src='http://www.arcgis.com/apps/View/index.html?appid=...' frameborder='0' scrolling='no'></iframe> Refused to display 'https://www.arcgis.com/home/signin.html?returnUrl=http%3A//www.arcgis.com/apps/View/index.html%3Fappid%...' in a frame because it set 'X-Frame-Options' to 'deny'.
GET https://www.arcgis.com/home/signin.html?returnUrl=http%3A//www.arcgis.com/apps/View/index.html%3Fappid%... net::ERR_BLOCKED_BY_RESPONSE I'm just wondering if there's anything I need to configure in the map or app itself in order to ensure it displays on my page, regardless of whether the client is logged into ArcGIS Online in their browser or not. Or is it not possible to disaply a web map/app in an iframe if the client is not logged into AGOL? edit: I'm marking this as "assumed answered" as the cause of the issue was determined to be a layer in the map did not have the proper sharing settings. I set the layer to share with the public, and the embedded app displayed correctly in my web page.

I need to insert a new row into a featureless table in a file geodatabase, but I can't seem to find anything the ArcGIS Pro SDK community samples or pro snippets. Does anybody know how this can be done and/or can point me in the right direction?

I've noticed that sometimes I get a System.ArgumentException when attempting to add a layer at this line: LayerFactory.Instance.CreateLayer(new Uri(uri), map) var 'uri' is a string containing the full path of a .lyrx file (ex: "D:\Data\my_layer.lyrx"). If the path is on a shared network drive, some of the time I get the exception. I'm also unable to navigate to that folder in the ArcGIS Pro Catalog. Sometime it does work, however but it seems random. There is no loss of connection to the folder in Windows Explorer when this error occurs. Is it possible to force a refresh or reconnect to the network folder before attempting to access files? Has anyone else experienced a similar issue?

Thanks for this! Do you happen to remember which community sample demonstrates this? I must just not be seeing it...

I'm having a hard time figuring out how to get the currently selected item in a ComboBox. I couldn't find anything demonstrating this in the ArcGIS Pro SDK Community Samples, but I may have missed or overlooked this. The RibbonControls solution demonstrates the combo box and button click, but I can't figure out how to get the combo box selection when the button is clicked. Can anyone point me in the right direction?
