Hi, Here is the code for taking the screenshot of the map. I think you have to use your own hosted layers to get the layers in the screenshot. With this code you can download the image with high resolution. If you want to decrease resolution then you have to the below statements. canvas.toDataURL("image/jpg", 0.5); I can't attach the supported file here so you can download the below mentioned script files from the internet 1. html2canvas.js and html2canvas.svg.js 2. html2proxy.php from the screenshot widget 3. filesaver also from the screenshot widget. <!DOCTYPE html> <html> <head> <title>Test screen shot</title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no"> <link rel="stylesheet" href="https://js.arcgis.com/3.23/esri/css/esri.css"> <style> #tools { top: 20px; color: #444; height: auto; font-family: arial; right: 20px; margin: 5px; padding: 10px; position: absolute; width: 115px; z-index: 40; border: solid 2px #666; border-radius: 4px; background-color: #fff; } html, body, #mapDiv { padding:0; margin:0; height:100%; } button { display: block; } #mapDiv{ height: 100%; } </style> <script type="text/javascript" src="html2canvas.js"></script> <script type="text/javascript" src="html2canvas.svg.js"></script> <script type="text/javascript" src="CanvasToBlob.js"></script> <script type="text/javascript" src="fileSaver.js"></script> <script src="https://js.arcgis.com/3.23/"></script> <script> var map; require([ "esri/map", "esri/layers/ArcGISDynamicMapServiceLayer", "dojo/dom", "dojo/on", "dojo/domReady!" ], function( Map, ArcGISDynamicMapServiceLayer, dom, on ) { map = new Map("mapDiv", { basemap: "streets", center: [-25.312, 34.307], zoom: 3 }); map.on("load", init); var demographicsLayer = new ArcGISDynamicMapServiceLayer("https://sampleserver6.arcgisonline.com/arcgis/rest/services/Census/MapServer"); map.addLayer(demographicsLayer); function init() { on(dom.byId("screenShotTool"), "click", function(evt) { screenShot(); }); } function screenShot(){ // html2canvas(document.getElementById('mapDiv')).then(function(canvas){ // document.body.appendChild(canvas); //}); html2canvas(document.getElementById("mapDiv_container"), { "logging": true, //Enable log (use Web Console for get Errors and Warnings) "useCORS": true, //"allowTaint": true, "proxy": "html2canvasproxy.php", // "timeout": "0", onrendered: function (canvas) { //document.body.appendChild(canvas); //this.screenshotDataURI = canvas.toDataURL("image/jpg", 0.5); canvas.toBlob(function (blob) { saveAs(blob, "Screenshot.png"); }); } }); } }); </script> </head> <body> <div id="tools"> <button id="screenShotTool">Screen shot</button> </div> <div id="mapDiv"></div> </body> </html> Please let me know if you have any questions.

Hi I am just inserting a new record in sharepoint using soap services. As per my request client moved sharepoint application to https. Problem is sharepoint will use credentials to insert a new record and will use NTLM authentication. I hardcoded the credentials in the widget.js file right now. I would like to keep in the proxy.config. Can anyone please tell me how to do that? Cheers, Srikanth Dasari

Hi, Issue got resolved. Actually, I am using esriRequest for a non-esri "SharePoint" service and I have used dojo/request/xhr to resolve issue. Now, I am facing issue with the mixed content "Mixed Content: The page at 'https://localhost:44397/' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'URL'. This request has been blocked; the content must be served over HTTPS" Please give me some resolution. Cheers, Srikanth Dasari

There is a hierarchy in SharePoint.. Website --> List Items (Forms) --> items (Records) In order to create a new record in one of the Form --> https://sp/ops/Portal/_api/Lists/GetByTitle('FormName') --> Will give access to the form--> https://sp/ops/Portal/_api/Lists/GetByTitle("FormName")/items --> Will give access to the records either to create or query Cheers, Srikanth Dasari
