Dialog Box on Radio Button Select
I have a two element value list for a radio button control on one of my layouts, that when the buttons are selected or changed, a variable is set. I am trying to make it so that when the user clicks on the other choice (the button not pressed currently), a dialog box comes up asking for confirmation (are you sure you want to do this? ok, cancel). Then when the user clicks ok, the radio button changes selection. How can I do this? Thanks.
