How to open new window in asp.net and disable the old one?

Question

I have an asp.net web page with a link button on it. When I click the button I need a new web page in a new window to be opened. While the new page is open, the old one should not be active. When I close the new page I need to return a value to the old page. Can you tell me how can I do that? Thank you very much in advance!

Answer 1

You want to use a Modal popup for this, basically a popup that will take focus and can't return to the containing page until the user closes the popup. You can pass variables in the usual way.
