Pass parameters from datagridview to report

Question

I have a datagridview with various info that I want printed on a label.  I added a button column to the DGV, so when the user clicks the button it automatically will print the desired label.  But i cannot figure out where or how to pass the parameter from the datagridview to the report.  I created a parameter on the report designer, it is looking for a reportparameter1, but i cannot figure out how to set that parameter, or where.  

thanks
