Partially Pre-populate InsertItem with Secondary Datasource

I have one field in a Formview's InsertItemTemplate that I would like to pre-populate from a datasource other than the one that is bound to the FormView.

The details are as such: my main page allows a user to create a new relational record for a customer.  When a button is clicked to create this new record a formview is presented in a new window.  The URL contains two query parameters, editorWorkorder.aspx?id=new&companyId=232 .  The id=new puts the formview into Insert mode, and the companyId=232 determines should be saved along the new workorder so I'll know what company the new workorder belongs to.

Everything works fine.  However, I realized I would like to display the company's name in the formview while it is in Insert mode to remind the user what company the workorder is being created for.  Also because I just really, really want to.

I can retrieve the company's name through another query, but how would I get the name to display in a label inside the formview while the formview is in insert mode and bound to a differnt datasource than I am retireving the company name from?

I would create a function that takes the companyID as a parameter and returns the company name. Then you can put a label in the InserItemTemplate and set the text = '<%# FunctionName(Eval("companyID")) %>'

Then in your function do a lookup on the database and return the compnay name for that specific ID

That's exactly what I did.  Shame on me thinking there was an easier way - not that this was hard.  Thanks for your reply.
