Can’t access the XRM object inside the Web Resource, the Scenario I am in is, on an Entity Form, I have embedded a html web resource A as IFrame, and after some process ton hat A web resource open another html web resource B.

On a web resource A, I can access the form attributes via ,

window.parent.Xrm.Page.getAttribute("Field1").setValue("ABC");

but on web resource B, I cannot access the attribute.

window.parent.Xrm.Page is always null.

Is there a way around to access a CRM Form attribute on a Web resource ?

I am currently using CRM 2016 on premises.

Thank you.

If you are opening a modal dialog, then you will not be able to access the parent Xrm context - you will need to pass the values in and then when the dialog is closed, update based on the result.

If you are opening a non-modal dialog then you can use window.opener

Hi Guys

Thanks for the replies, the scenario I am in, I needed to update a filed value on CRM Form from a web resource which opened in a dialog.

Scott, Thanks for confirming "you will not be able to access the parent Xrm context from modal dialog". or i would still be looking to achieve this.

I have now achieved the work i was doing by using codeplex alert.js.

Thanks again.
