Hi,
Implementing radio buttons in the grid - where the user can only select one row at a time - probably entails a custom cell with a radio button in each row - where the 'name' property is the same for all the rows. A search in the grid forums for the keyword 'radio' did not yield a result. Since this could be a fairly common scenario was checking to see if there is a sample for this that has already been created.
Thanks and regards,
Amit
