Today i was just trying to check if the dependent picklist code generated using Microsoft Dynamics CRM Demonstartion Tools for CRM 4.0 will work for CRM 2011 or not.
So i downloaded the tool
I was able to connect CRM 2011 using that tool. Then i generated the code using the tool.
I tried using that code inside CRM 2011 and it worked properly.
Only thing we need to do is to wrap the entire onload code generated by tool inside a function and call that function on the onload of the form and same thing for the onchange code.
