The following sections describe your options if you want these controls to show more than static content. You can use one of the following web resources to display the contents of web resources in a form: It is recommended to use Power Apps component framework components if you're considering to use a web resource to show content that users will interact with.ĭisplaying a form within an IFrame embedded in another form is not supported. You can use an IFRAME to display the contents from another website in a form, for example, in an ASP.NET page. If your IFRAME depends on access to the Xrm object of the page or any form event handlers, you should configure the IFRAME so that it's not visible by default. Web resources and IFRAMEs aren't displayed using the Dynamics 365 for Outlook reading pane, however, they are supported in Dynamics 365 for tablets. Shortly after posting this blog, Christopher commented that using attachEvent() on the iframe element works in IE.The designs you choose for the form are also used for the Dynamics 365 for Outlook reading pane and forms used by Dynamics 365 tablets. With YUI, I’d just use Y.UA.ie to determine this (you can use whichever method suits you best). I considered using the existence of document.readyState to determine whether to use readystatechange, however, most other browsers now support this property, so that’s not a good enough determinant. I would have preferred to check for the existence of iframe.readyState, however, this throws an error when you try to access the property prior to adding the iframe into the document. The check to determine if the browser is IE or not is a bit messy. Example: function getIframeWindow(iframeElement) (iframe) Internet Explorer prior to version 8 didn’t support this property and so you had to use the proprietary contentWindow property. This is the standard way to retrieve the iframe’s window object and is supported by most browsers. The iframe element object has a property called contentDocument that contains the iframe’s document object, so you can use the parentWindow property to retrieve the window object. When the domains match, the containing page can access the window object for the iframe. In order for the containing page to access the iframe’s window object in any meaningful way, the domain of the containing page and the iframe page need to be the same ( details). The window object representing the iframe content is the property of the page that was loaded into the iframe. The iframe element itself,, is owned by the containing page, and so you may work on it as an element (getting/setting attributes, manipulating its style, moving it around in the DOM, etc.). The missing piece of intrigue in most discussions surrounding iframes is JavaScript object ownership. In all ways, the containing page and the iframed page are cut off from communication (which has led to the cross-document messaging API in HTML5). This cross-domain restriction goes both ways as the containing page also has no programmatic access to the iframe. Iframes provide a level of security since JavaScript access it limited by domain name, so an iframe containing content from another site cannot access JavaScript on the containing page. In this new Web 2.0, mashup world that the Internet has become, a lot of focus has been placed on the use of iframes for embedding third-party content onto a page.
