Hi guys,

Has anyone encountered and solved this problem. BTW. i'm migrating an old asp.net 2.0 website to vs2010/ .net4.0. Whenever I open a window without parameters they open fine. such as openGoogleWin(). but when i use a function with parameters such as openYahooWin('www.yahoo.com') i get an 'undefined' is null or not an object error.

my javascript code is as follows:

Hello Hugo,

Is there a reason why your not passing the url in the radopen call? Maybe that could make a difference. Also, is the undefined error being caused because of your url not existing or something else? Have you tried debugging it using FireBug or IE Developer Toolbar for IE8, to see where the error is being thrown by?

I hope that helps.

Hi Hugo,

The code that you posted looks OK (just keep in mind that you need to provide the full Url as the parameter, i.e. openYahooWin('http://www.yahoo.com') or you would get a "resource cannot be found" error because the browser will look for a file called www.yahoo.com in your project's folder.

At this point I cannot tell what the reason for the problem might be, but if you send me a sample application, I will check it and get back to you right away.

Sincerely yours,
