I have an instance of CuteEditor on a page with web controls that use AJAX .NET.  When I interact with one of these web controls (like, say, pressing a link button) I get a hard exception from Cute Editor :

 

System.Web.HttpException: Filtering is not allowed.

Try adding this to the app settings:

I am also receiving a similar error in IE 6, from the CuteEditor instance.  I get a client side debug error:

 

Sys.WebForms.PageRequestManagerServerErrorException: Filtering is not allowed

 

Any ideas?

Try adding this to the app settings:

acer152,

I am updating the only web.config for the site, in the site root.  Should there be one specific to CuteSoft?

 

Also, notice the difference in error message:

 

System.Web.HttpException

 

vs.

 

Sys.WebForms.PageRequestManagerServerErrorException: Filtering is not allowed  (the one I get)

 

Not sure if that makes a difference for your answer.

 

I get the same error when I insert the editor inside an MS AJAX <edititemtemplate> of the ReorderList control.

Adam - Do you have any comments on this?  Seems that UpdatePanels should not cause this error.  I have UpdatePanels as well, but not on the editor.

 

Actually, I don't have any UpdatePanels on the page this is occuring.  I have a couple frames with update panels in them, but not the actual page.   I have the Cute Editor inside a <formview>, but no UpdatePanels.

 

Any ideas?

hbielich,

Adam,

I worked all morning to make a "Simple" page to do what I described in the previous post - by trying to duplicate the error by placing each GridView/DetailsView set in it's own updatepanel.

It now seems to be working properly though!  The main difference between the "Simplified" version and the one I had trouble with, is that the page that came up with the error used a master page.  I am not sure if that is the problem yet though.  There is so much to keep track of in the aspx code that I need to go over it in very fine detail again to see if I can determine the cause. I will come back with my findings when done. At least I have discovered the value of those expand/contract (+,-)markers in the margin to help visualize specific sections of code.

Anyway, it at least looks like there is no problem when not using MasterPages.  We'll see if that's the problem...

 

PS

  There still is a problem with the DetailsViews controls in design mode showing "There was an error rendering rhe control. Exception has been thrown by the target of an invocation.  But they do function properly. 

Adam,

  I just constructed a page using a MasterPage and incorporated the "simplified" version.  Everything appears to be working properly, so the problem I saw earlier must have been with some code error I made - My Bad!

Still get the rendering error, but I'm happy with the correct functionality.

hbielich,

I'm glad you found it!  I thought it was in my code because when I made the simplest version it worked ok, but I've been trying like heck to find the problem with my code in the more complex versio, but have had no success.  I will now put each update panel on its own page.  Hopefully there won't be a problem with that.

How long before the newv ersion comes out?

I've got this error as well.  But it only started happening when I converted my project from Visual Studio 2005 to Visual Studio 2008?   Anyway I have uploaded a new Visual Studio 2008 project I created that reproduces the problem.  Note the problem only happens in IE7 with Tools | OPtions | Advanced | Browsing | Disable Script Debugging (IE) is UNTICKED (that is it enables script debugging)... so normally you wouldn't see it.  

 

Could you please have a look at this ASAP.  Thanks.
