Implementing lookup pages

[Kursat]

Hi,

In my Windows applications I generally use lookup forms to show a list of
values to users and these windows are generally modal. Users select any item
from list, press OK button and details are displayed on main window. I want
to implement same logic in my ASP.NET applications but I have no idea about
some points such as : "How can I display a modal browser window?", "How can
I get selected item from lookup list when user select an item and then close
modal window by clicking OK button?", "Is it convenient to use this approach
in web applications?"

I want to know your answers for questions above.

Thanks in advance.

Modal dialogs in WebForms are a little trickier than in WinForms.

If you can guarantee that all users of the app will be using IE (e.g. maybe
in a corporate intranet), then you can use:

This can be used to return a value to the calling code in the parent window,
which could be a variant array if you need to return more than one
"value"...

If you need cross-browser support, then you will need either to find a
different method or simulate a dialog by means of a <div> - Ajax has this
built-in:

You could check out the modal popup with AJAX:
