I have created a dataTable that supports row selection using radio buttons. Now I want to perform delete,modify, and view operations on the selected row. I created commandButtons and set actions. It works well.
Now I want to show a popup messagebox that shows "Please select a record." message , if the user try to execute any of the view,delete,update operation without selecting a row.
