Advanced form causes page freeze on save or cancel

[Leighton]

I seem to be having issues with the advanced form on the radscheduler causing the page to freeze when the save or cancel buttons are clicked.  The advanced form does not close, and the ajax loading panel displays the updating graphic, but the scheduler does not update.

This issue seems to occur consistently with all attempts to use the scheduler.  I first tried to adapt the Outlook scheduler example, and then tried again this morning with a basic scheduler scenario and encountered the same issue.

The examples work fine when run on my local machine, so could it be some server configuration issue with our production server that might be causing this?

The production server is a Windows 2003 / IIS 6 setup.

Hi Anthony,

Could you please check if you receive any Javascript errors. Also please stop the AJAX via EnableAjax="false" in the RadAjaxManager and check whether you are receiving some error in code. I assume that some scripts are not loaded correctly but I am not sure until you tell me whether you are receiving some errors.

Best wishes,

Hi Veronica,

Thank you for getting back to me.  With AJAX disabled, Firebug is showing the following error:

i[0] is undefined

On line 32 of RecurrenceEditor.js.

if(i[0].checked){h.show(); }

The advanced form also does not launch now.

Any luck hunting this down?  Is there anything else I can supply that would help diagnose the issue?

Hi Anthony,



In the ticket info I see that you are using version 2011.1 315. Can you confirm this?



Also could you please send me  a sample project that reproduces the issue so I can inspect it and help you?



Thank you!

The version number is correct, yes: v. 2011.1.215.35

You can download the test solution from http://www.wildhoneymedia.com/files/testbed.zip

It was too large to upload the zip file.  ScheduleTest.aspx is the test file with the scheduler.

Thank you again for the help!

I have since upgraded to v. 2011.1.413.35 with the same results as before.

Hi Anthony,



I ran your project and I successfully created and edited appointments in the advanced form without any freeze in the Advanced Form.



However I suspect that maybe on your production server some scripts are not loaded correctly.



Could you please tell me whether you got the same issue with our "Advanced Templates" demo as I am not sure how to reproduce the issue on my side?



P.S: I saw that your Advanced Form looks transparent. This is a known issue and you can see how to fix it in this sticky forum post for Q3 2010.

I'm having the same issue when I copy that demo to our production server.

i[0] is undefined
http://aspnet-scripts.telerikstatic.com/ajaxz/2011.1.315/Scheduler/RecurrenceEditor/RecurrenceEditor.js
Line 32

this._pickers.startDate is null
http://64.18.218.208:3811/scheduleTest/AdvancedForm.js
Line 566

I am almost certain the issue is with our server, rather than the code, but I can't pin it down exactly.

Wow.  Okay, I found the problem!

The website was set to run using .NET 4.0.  For some reason we seem to have a configuration issue with that.  Downgrading the website ASP.NET version to 2.0.* and using 3.5 directives in the web.config file has solved the problem.  It's an adequate solution for us since we don't develop using .NET 4.0 anyway.

Thank you for helping me track this issue down!

Hi Anthony,

I'm glad that you found the solution.

Please feel free to ask me if you have further questions.

All the best,
