CRM 2011 | 从Javascript窗体触发Silverlight函数

Question

I am working on CRM 2011 online. I have a form and added a Silverlight web-resource to it. And when a lookup value changes, I need to trigger/invoke a Silverlight function. I followed this guide exactly and a few other guides with same concept but still not able to run it properly due to this statement:

silverlightPlugin.Content.interactionObject.FormAttributeChanged(attName, attValue);

I used the IE debugger and found the the Content property is always undefined . Why it's undefined ?

Has anyone came across this before?

Answer 1

I will answer my own question:

The problem was that I was referencing the HTML page instead of the .XAP.

After debugging the Content property was set.
