3 data sources for detailviews control

I am looking for addititonal references for how to bind data to a C# detailsview 2010 web form control. Some of the links I have located so far are the following:

http://www.asp.net/data-access/tutor...iew-control-cs.

A standard linq datasource control can be connected to the detailsview control in standard situations as listed above. For data that is loaded into the detailviews control, I need to add 2 dropdown list controls values, data from an excel spreadsheet, and data obtained from tables not in the production database. Thus in this case, I am looking for additional refernces on how to bind these other references to the detailsview control when data is first loaded into the control.

IF I get it correctly you want to add columns and their respective data from 3 different data sources. Try the following links
