File Download from window.ShowModalDialog

[Guest]

Hello,

Using asp.net 2.0, C# and IE7

I'm using window.showModalDialog to open a modal window on the client from
Javascript.
I have to include this line in the < HEAD > html of the modal window:
<base target=_self> because whenever that page posted back, it would spawn
off a new window!! This is the beaviour in IE7.

In this Modal Window I need to have a File Download functionality.
The problem is that using <base target=_self> the File Download dialog don't
popup, but if I remove the <base target=_self> the File Download dialog
appears but it would spawn off a new window from the Modal Dialog.

Thanks for any suggestions on how to resolve this issue

And in earlier versions...

That's correct.

The easiest method is simply not to use showModalDialog - it's completely
non-standard, and only works in IE and some versions of Safari...

Why do you need to use showModalDialog anyway...?

Hi Mark Rae,

Thanks for the advice but I'm mimic a WindowsApp to WebApp, so I have to
create the UI as close as possible.

In respect to this problem I work around it creating a dummy dialog that
only writes out an iframe with src = the dialog i want to load.

thanks,

WinForms and WebForms are fundamentally different - I wouldn't advise this
approach at all...

Modal dialogs are fairly easy to simulate with <div> controls:

Thanks for this new approach, I tried the sample and it has the behaviour
very similar to the window.ShowModalDialog(...), since this is more standard
I guess I'll have to change all my ModalDialogs.
Thanks again for your help
