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. ...

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? ... View more

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. ... View more

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? ... View more

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? ...

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? ...
