Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Object reference not set to an instance of an object.

[burak]

Hello;

I did a small project and I use the template exam. It works fine. However I want to use the same in my real project and I took this error message.

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Object reference not set to an instance of an object.

I search in google and this forum and I cant find any answer. I receive this error on double-click on the scheduler.

Thanks...

Hi burak,

This is a server side exception which is reported by asp.net ajax. You can disable temporarily ajax to see what is causing the server-side exception.

Sorry , How can i disable ajax in my project ? I'm using vs2008 and RadControls for ASPNET AJAX Q1 2009

Hi burak,

If you are using RadAjaxPanel or RadAjaxManager you could set the EnableAJAX property to false.

Kind regards,

Hello,
I found something but I can't understand why.
I use ajax enabled radajaxpanel and in the same page I've got radpanelbar. They dont work together but when I remove radpanelbar I can use ajax controls. Or when I disable Ajax controls work again.

How can I solve this problem ? And Why it's happen ?

Note : radpanelbar in a usercontrol...
