Pass parameters to IFrame on dashboard CRM 2011

I want to show a aspx page in an iframe on a custom dashboard. But this page needs some extra 开发者_StackOverflow社区parameters. How can i adjust the url from this iframe so i can pass the values from crm 2011? I can't find where a trigger or something like that where i can call some javascript code.

Thanks in advance.

What kind of information are you looking to pass?

If the record object-type code and unique identifier isn't enough, then you could do one of the following:

• use a web resource instead and have an iFrame inside the web resource.
• connect via the organization services from the custom aspx page and query what you need.
