I have main aspx page with a button that will show a modal
dialog in the Browser when a user clicks on the button.
On the modal form the user will do some selections.
The he will submit his selections to the server via a postback.
How can I take these selections to the main page?
Thanks 6 8140

I have been struggling with the same problem recently and have come to the
conclusion that I need to rethink the whole architecture for the following
reaons:
1) AFAIK, window.showModa lDialog(...) will only work for IE so, if you're
writing a public-facing site, you're going to run into severe cross-browser
issues.
2) It is possible to return only one value to the main form using the var
intReturnValue = window.showModa lDialog(...) / window.returnVa lue
functionality so, if you need to return multiple values, pretty much your
only option is to use Session variables.
3) When you submit a modal dialog, it will launch a new browser instance
unless you enclose it in an iframe - again, this may not be supported in
certain browsers.
Mark,
I have overcome this by passing in "window" to the modal dialog. Then,
with this reference, client script can modify anything on the parent. If
you need pass information back to the parent, you could set some hidden form
fields on the parent through the window reference you have, and then post
the parent back to the server.
Best regards,
Jeffrey Palermo

That's interesting - hadn't thought of that. Do you have a solution to the
submission problem too?

returnValue is a variant. You can return an object with many fields. For
example, if you need to return value a=1, b=2 and c=3, you can make it in
the dialog window in the following way:
var outputObject=ne w Object();
outputObject.a= 1;
outputObject.b= 2;
outputObject.c= 3;
window.returnVa lue=outputObjec t;

Excellent! Thanks very much.
Mark,
No, I haven't ever posted back a page from inside a dialog. I always
used javascript to place some values on my parent page (maybe in a hidden
form field), and then I close the dialog. If I have a onchange handler on
my hidden form field that changes, then I could tell the parent to post back
as soon as that value changes.
Best regards,
Jeffrey Palermo

Beginner question - please be patient with me :-) I am new to c#.
If one creates a child modal (and also non-modal) form what is the
best way of returning the collected data back to the calling form?
For example, say off of my main form I launch a modal dialog box that
gets the username and password what is the best way of passing that
data back? The info has to go into an object eventually so I can
