I'm actually not super familiar with the collection widget, but the collection widget is based on an infotable of information for which you can provide a json to bind information from that table to contained mashups shown in the collection.

My thought is that this would mean you can't pass a separate parameter directly through the collection widget.

Either you pass that using Session Parameters or you use the selection to regenerate the infotable provided to the collection widget.

Thanks for your reply, Can you please explain in detail how do I used session parameter for collection??please refer above attachment .

Session parameters are variables available across the user session. You'll see them in the mashup builder in the Session panel on the data side. You can bind to and from them in any mashup you are designing.

So from a parent mashup you can wire information in, then in the collection 'child' mashup you can take that value and use it. It also comes with 'Session Parameter Value' changed event to trigger services, if that isn't there or not working, you can wire the session parameter first to a mashup parameter and do it that way.
