.NET Forum / ASP.NET / General / October 2007File Download from window.ShowModalDialog
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 Joao Rego > Using asp.net 2.0, C# and IE7 > [quoted text clipped - 3 lines] > <base target=_self> because whenever that page posted back, it would spawn > off a new window!!

That's correct. > Thanks for any suggestions on how to resolve this issue 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...?  SignatureMark Rae ASP.NET MVP http://www.markrae.net 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, joao rego > Thanks for the advice but I'm mimic a WindowsApp to WebApp, so I have to > create the UI as close as possible. WinForms and WebForms are fundamentally different - I wouldn't advise this approach at all... > 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. Modal dialogs are fairly easy to simulate with <div> controls: http://www.hell.org.ua/Docs/oreilly/webprog/DHTML_javascript/0596004672_jvdhtmlc kbk-chp-6-sect-10.html SignatureMark Rae ASP.NET MVP http://www.markrae.net 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.
