Hello Jorge,

You could try removing UpdatePanel or ModalPopupExtender controls and observe if the issue is related to the RadControls. I tried to replicate the issue which you described, but to no avail. Attached to this message, you will find the code which I used for testing. Please, take a look at it and let me know if there are any differences at your end, which I may be leaving out.

All the best,

Hi Antonio,

At firts i must say that you are using a different version of the AjaxControlToolkit, as i said before i am using: ajaxcontroltoolkit Version=3.0.30930.28736 

Another thing i forgot was to say that my version of development is for Visual Studio 2008 frw 3.5 with RadWebUI version: 2010.2.713.35

Maybe with that fixed info you can try your example again using the exactly version of the assemblies im using

I will appreciate your help.

Hello Jorge,

I have updated the assemblies and the .NET Framework version but still not able to replicate the issue. In order to further investigate and advise you with the best possible solution you could take a look at the project and describe what are the necessary steps for replicating the issue.

Hello Antonio,

Sorry for this late response.

I was looking and modifying your example for make it works, by that way i am sending you a VS2008 Solution with a webapplication project, you will find two pages:

WebForm1: shows the error when you close de popup (using radcontrols).
WebForm2: shows the same technique of opening and closing the popup with asp.net controls. So there is no error.

I think something is happening  in the way I MUST open and close the popup, this is because i need to control what happen before opening and also after closing the popup.

This is the link for download the file. Sorry for this, but i can not attach a file of 8MB.

I will appreciate your quick response.

Update 15/03/2012:

I tried to apply the "ajaxify" method of the radscriptmanager telling that the button updates de panel but i'm still getting the same error with datepickers.

Hi Jorge,

Thank you for the provided project.

I have tried to download the application from the URL but without success as it is shown in the video below. You could upload the project at another place and prove the new link.
