Add Drop down list to data table

Question

I am creating a search application that searches files and returns the article the hit generated from and the number of hits. I get the name of the article and the number of times it was hit from a stored procedure. Now I need a drop down list as the third column in the data table that will give me the option to select the individual files associated with the hits.

How do I add the drop down list to each row and bind it to a different data sources based on its hits.
