Hello,
I am trying to create a page for a timetable system. It has two drop down lists, one containing departure points and one containing destination points. I would like to be able to check that the user has not selected the same stop as both the destination and the departure point.
I have created this using a simple lable, and hiding/showing it as required when the user clicks the continue button, but I would like to be able to do this using one of the built-in validators, so that the user gets the instant response rather than only after they click the Continue button.
So, to my question - is it possible to access another controls data from within a validator? Or can a validator only be associated with one particular control?
I assume it's also possible to recreate this sort of action using some javascript?
Any help would be appreciated.
Thanks,
Ben.
