I am creating an ASP.NET website that has a list of 25 links (linkButton controls). If someone clicks a link, I want to check to see if their ZipCode is saved in a cookie - if not, I want to pop up a modal popup box that asks for the zipcode.
I have the modal popup box working - I can check to see if a cookie has been set(on the codebehind page) - but i can't do it without post back. So the page refreshes before showing the modal pop up and it doesn't look quite right.
Does anyone have any ideas how I would go about this?
Thanks for the help! I'm learning by doing - so I hope this makes sense.
