select row from gridView

Question

Hi

 

I'm trying to make a selectable row from a gridView to insert directly some values to another table

 

 

user will be registered to selected event by clicking to Register column value..

 

it will be stored on Reg table taking ID & name from user table as well as Regolator & Location from event table

 

 

can you help me to do this function ?

 

thanks
