Hi,
I'm trying to ensure that the user can't click Next until an entry is clicked in a dynamically created ListBox. The ListBox is populated by a PowerShell script custom action (to list certificates for the user to pick for binding to the IIS websites we're creating). This all works great, but there's a "bug" that I can't work past where the user can elect to not click an entry in the displayed list and then the installer fails.
Is there a way that I can disable the Next button until the user clicks a certificate? I've tried setting AI_LISTBOX = "" disable and AI_LISTBOX_DATA <> "" Enable but I think the ListBox always has data once it's been populated, so this doesn't appear to work.
