Hi
I have a large form (Approx 120 kb) in which i use a combination of Peter Blum's VAM controls, the ordinary aspx controls and telerik controls. In the page I have just upgraded the solution from Promethious 2007-Q3 to the newest version.
I tried to insert the Form Decorator to give the site a more complete look, and therefore I inserted the following line:
<telerik:RadFormDecorator ID="RadFormDecorator1" DecoratedControls="All" Skin="Office2007" runat="server" />
When I open the page, the site looks fine an the Form Decorator works perfectly, but when I try to exit the page, i get the error:
Line: 6
Error: '_events' is null or not an object
If I remove the formdecorator I won't get the above error.
Because the page is very large, it makes it difficult to isolate the error. So any help or clues as to why this might happen would be greatly appreciated.
Thanks in advance

I assume that the issue might be related to integration of RadFormDecorator and AJAX but since I do not have your code I can only assume what might cause the issue. However, some bugs concerning the RadFormDecorator control were fixed and I suggest to first test your project with the latest "Futures" release, namely 2009.1.220.20 and check whether the problem is fixed there.
In case it is not, you should replicate the issue in a separate demo, open a new support ticket and send it to us along with detailed reproduction steps because we need to examine what is actually happening locally and we are unable to reproduce this error in a basic setup (it does not exist in our demos for example).

I am using version 2009.1.311.35 and am getting the same error. I remove RadFormDecorator and the error goes away.
The error only happens on one page that has serveral AjaxControlToolkit PopupControlExtenders.
Thanks

We are aware of this problem and we are currently working on it. For the time being I recommend you declare the RadFormDecorator control under all of the AjaxToolkit controls.
For example :
<form id="form1" runat="server"> |
<asp:ScriptManager ID="ScriptManager1" runat="server"> |
</asp:ScriptManager> |
<div> |
<asp:Panel ID="Panel1" runat="server"> |
<asp:Label ID="Label1" runat="server" Text="Text 1"></asp:Label> |
<asp:Label ID="Label2" runat="server" Text="Text 2"></asp:Label> |
</asp:Panel> |
<br /> |
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> |
<ajaxToolkit:PopupControlExtender ID="PopupExtender1" runat="server" PopupControlID="Panel1" |
Position="Bottom" TargetControlID="TextBox1"> |
</ajaxToolkit:PopupControlExtender> |
<telerik:RadFormDecorator ID="RadFormDecorator1" DecoratedControls="All" Skin="Office2007" |
runat="server" /> |
</div> |
</form> |
In this case all of the controls on the page work without any problems.
I hope this helps.

Not only is this a #@$$%! annoyance, my RadGrid no longer will display the data.
Can you please check whether this issue appear with the Q2 2009 SP1 release of RadControls for ASP.NET AJAX (2009.2.826)?
If the problem remains, I will appreciate if you isolate a simple working version of your project (including a dummy data source for the grid since the actual data is most probably not relevant to the issue) and send it enclosed to a regular support ticket. We will test it locally and will get back to you with our findings.

If you experience this problem I would suggest to update to a recent version of the control (like Mark did) and if the problem persist - to open a support ticket and to send us a small sample application that reproduces this issue. We will check it right away.

1. I have page A (userlisting.aspx) with a radgrid that show all the systems users and a aspx button decorated with the form decorator which is a Add User (response.redirect("usersetup.aspx") -->
2.click the button and everything works fine...
3. in usersetup.aspx (page B) I have other aspx button which is Close (response.redirect("userlisting.aspx")
4. when I click the close button which has no other instruction than the response.redirect, the error occurs.
I have other area similar scenario but i did not update the controls yet: page C with aspx gridview, aspx button redirects to page D with imagebutton (close) I click close and the error appears too. Pages C and D, I did not change a thing yet (I did not update with radcontrols yet) but I remove the form decorator from the masterpage and everything works fine
I tried to reproduce the problem locally but to no avail - everything is working fine on my side. It is possible that I am missing something in your setup so I would like to ask you to open a support ticket and to send us a small sample project where this issue could be reproduced. We will check it right away and do our best to help.
Thank you in advance for your cooperation.

I notice that the id (ctl00_ContentPlaceHolder1_chkActive) in my case is a checkbox control with a ajax extender (mutually exclusive).
What happened in this case, the thing is that the checkbox has a ajax extender but a have no other related checkbox to use the extender to make the multually exclusive. In other words i had a ajax extender in a control which i dont need to use. I suggest to verify the error in the web resource file when the debuger stops and highlight the control with the error.
I verified the other page that I had the same error and guess what... I had another extra ajax extender like the first one related above with the chechkbox.
Thank you for the information - I am sure it will be of help for other users that have stumbled upon such problem.
