Hi hope you guys are fine.
I have one html web resource and I have JAVASCRIPT in this html web resource plus I have IFrame in this html web resource as well. I have inserted this html web resource on custom entity form using web resource icon menu on main form of entity.
On Page load when i try to access IFrame like this document.getElementById("iframeid") I get IFrame control but when I try to get IFrame using Xrm.Page.ui.controls.get("iframeid") or Xrm.Page.getControl("iframeid") i always get null.
In IFrame I am loading my Canvas app, my canvas app is embeded in model driven app via iframe.
just to let you know , I have html iframe in html web resource like this
<iframe id="myid"></iframe>
I have 3 tabs on form and iframe is on first tab which opens bydefault on page load.
I do not want to use document.getElementById because MS does not recommend it when when try to publish our app to MS app source.
Any idea what i am doing wrong using XRM api ?
1. Try either window.parent.Xrm.Page (not recommended) or parent.Xrm.Page (better, but the below may be recommended instead)
2. Use this example of getting form context first using this as a guide:

//Get the value of an option set attribute
var formContext = executionContext.getFormContext();
var value = formContext.getAttribute("new_pagechooser").getValue();
var newTarget = "";
//Set the target based on the value of the option set
switch (value) {
case 100000001:
newTarget = https://myServer/test/pageOne.aspx;
break;
default:
newTarget = https://myServer/test/pageTwo.aspx;
break;
}
//Get the default URL for the IFRAME, which includes the
// query string parameters
var IFrame = formContext.ui.controls.get("IFRAME_test");
var Url = IFrame.getSrc();
// Capture the parameters
var params = Url.substr(Url.indexOf("?"));
//Append the parameters to the new page URL
newTarget = newTarget + params;
// Use the setSrc method so that the IFRAME uses the
// new page with the existing parameters
IFrame.setSrc(newTarget);use executionContext.getFormContext(); to get the context first for example.
