    On the client-side you are restricted to the functionality available in
    HTML. It doesn't matter what you have on the server side. What the user sees
    in their browser is pure HTML.

    Default Re: Opening other ASPX pages

    Hello Juan,

    I've set up a modal dialog using an .aspx page that handles a data update
    event on the postback and then closes itself. It's a little clunky but it
    works.

    The important thing is to make sure that the form submit targets the same
    window, otherwise the browser will open a new one. This can be done by
    using the following in the window.onload

    window.name = "windowName";
    Form1.target = "windowName";

    The second thing is communicating to the client from the postback that the
    window is to be closed. I did this with a hidden input field with
    runat=server, the value of thisa is checked in the window.onload of the
    dialog, and if it's set to a particular value, the window is closed. I've
    also communicated the value from the server back through another hidden
    field.

    The big fat caveat with this is it only seems to work in IE 6 - the
    form.target property for modal dialogs is ignored in IE 5 (don't know about
    IE 5.5 yet). As I have the luxury of developing a fixed IE6+ client, it's
    not a problem.

    I've attached a demo, and the source here.

    Hope it helps...
