I am using the Item Template for this. I don't want the user to have to Select a row, before clicking on the checkboxes. Here is my non-working code to uncheck the other checkboxes. I realize it's not "SelectedRow" that I want since there's no selected row, so how do I find the row containing the checkbox that fired off CheckChanged?
