Embed datasource control in 2010 web forms

Question

In a C#asp.net 2010 detailsview and formveiw controls, I am asking what embedding various linq data source controls in certain cells. Basically I want to embed different datasources so the default dates will appear in  diffeent data cells. This allows the user not to have to enter the date unless there are some excpetions. The data would come from different tables in different datacontext production areas. Is this possible? IF so, can you point me to links that I can use to see how to accomplish this task?
