linq with webform control

Question

I have a linq data source control question for a new C# web form 2010 application I am writing. I need to bring in one schedule date table and one main table to the .net 2010 control to display. The schedule table is based upon the current processing month and year. The main table is based upon what was entered on the orginal application web.

Would you setup two separate linq data source obejcts and point them to the appropriate cells in the web form control? Would you select all the data you need  from the 2 unrelated tables in one linq statement and bring the data to the web form control? (The schedule dates are used to make data enter easier for the user. This keeps the user from having to enter dates.)

Can you tell how you suggest I accomplish this goal and point me to a references on how to complete my objective?
