Hi,

I'm opening a popup window with JavaScript. It has a command button.

This is from the primary source (opener) window:
###################################################################
// =======================================================
function popup01 ()
{
var win_url
= "http://localhost/Webfolder01/DBCtrl.aspx";
var win_name
= "DBpopup01";
var win_chrome
= "toolbar=0,scrollbars=1,location=1,statusbar=0,menubar=0,resizable=1";
var win_dimn
= ",width=444,height=444,left = 290,top = 162";

DBname_popup = window.open (win_url, win_name, win_chrome + win_dimn);
if (window.focus) {DBname_popup.focus()}
}
// =======================================================
###################################################################



When I click the command button on the popup window, and upon postback,
I get an HttpException:

[HttpException (0x80004005): The state information is invalid for this page
and might be corrupted.]

... along with:
[FormatException: Invalid character in a Base-64 string.]


I tried a suggested remedy [enableEventValidation="false"],
and it had no effect:
########################################################################
<%@ Page Language="C#" AutoEventWireup="True" Inherits="dyn_ctrl_page"
enableEventValidation="false" Debug="true" %>

########################################################################


Does anyone have any ideas as to what is causing this?

Is this a bug in ASP.NET?

I realize that I'm not supposed to cross-post, but should I
post this to the JavaScript forum as well?


Thanks in advance!
