Getting information from parent GridView to a nested GridView - asp.net

Question

I'm hoping someone can help me get data from a GridView into another GridView I made inside it. I'm trying to get the wo_id field from the first GridView into the second GridView's datasource (created inside the first).
Right now, in the code below, I have "tasks = tasks" in the WHERE clause of the "partsused" SqlDataSource, and I want it to use the wo_id field from the parent GridView instead (thus showing the correct list of parts for the specific work order).
