Every time you do a postback in a modal dialog it opens a new windows. I am
not sure why that happens, but there is a way to get around it. Instead of
calling the pop-up page, you will need to create an 'interim' .asp or .htm
page set up as follows:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<title>Add New Ship To</title>
<meta name=vs_defaultClientScript content="JavaScript">
<meta name=vs_targetSchema
content="http://schemas.microsoft.com/intellisense/ie3-2nav3-0">
<meta name="GENERATOR" content="Microsoft Visual Studio .NET 7.1">
<meta name=ProgId content=VisualStudio.HTML>
<meta name=Originator content="Microsoft Visual Studio .NET 7.1">
</head>
<body MS_POSITIONING="FlowLayout">
<IFRAME width='100%' height='100%' NAME="Frame1" SRC="<popuppage.aspx">
</IFRAME>
</body>
</html>
By having the popuppage in an Iframe and using the this 'interim' page as
the direct call from the javascript ShowModalDialog as follows:
var WinSettings = "resizable:no;dialogHeight:600px;dialogWidth:6 00"
var result = window.showModalDialog("interimpage.html",null, WinSettings);
This will eliminate the opening of a new window when the popuppage
refreshes.
Let me know if you have any other questions!
Thanks!

Not really sure if this is a javascript problem or C# - sorry if in
wrong place.
Modal Forms Question in Web Application
I have two web forms: Form1 and Form2
Form1 calls Form2 using showModalDialog
var WinSettings = "resizable:no;dialogHeight:600px;dialogWidth:6 00"
var result = window.showModalDialog("Form2.aspx",null, WinSettings);
Form2 has a ListBox, a Label and a Button. The listbox is populated
from a sql call to the database. The "SelectedIndexChanged" event
changes the text appearing on the label to the value associated from
the ListBox. The Button closes the form and returns the text from the
label. Form2 works properly when ran by itself.
However, when I load it using showModalDialog from Form1, the first
time the "SelectedIndexChanged" event fires, a new window opens up of
class Form2 rather than just changing the text in the Label field.
Any help would be appreciated.
