Hi Priya,

I recall a similar problem in the past with old version of RadControls for ASP.NET AJAX but it was fixed after that. Please make sure that you are using a recent version of ASP.NET AJAX and RadControls for ASP.NET AJAX and you should not experience this problem anymore.

Sir

I am using ASP.NET AJAX Q1 2008

[Jeff]

I'm using 2009.3.1314.35 and Priya's situation describes mine exactly:

• Open RadWindow from a button on the form with the following code: $find('{0}').show();
• OnClientClose clicks an invisible button to force a PostBack: $get(btnRefresher).click();

The PostBack results in the Invalid JSON Primitive exception.

I would appreciate your help in resolving this. Let me know if you need anything more from me to reproduce the problem.

Thanks,
Jeff

I guess I should have been paying attention to the errors my HTML Validator Firefox extension was alerting me to. I was adding the RadWindow to the form twice.

When you have two of the same RadWindows with the same DOM IDs, JSON isn't happy upon PostBack.

Once I stopped doing that, the problem went away.

Now, how do I mark my own post as an answer. :)

Thanks Jeff. That was very helpful.
