All,
I have two RadDateTimepickers within a MasterTableViewEditForm view in a radgrid. Everything works fine, but after interacting with the page or hitting the cancel button a few times, then I get the following error:
'this.get_timeview()' is null or not an object.
This only happens after going to edit a record and then hitting the cancel button after three times.
Below is the code for my RadGrid:
Any help would be greatly appreciated.

Hello Jon,
If your RadGrid is AJAX-ified, the described scenario usually happens when you initiate a new AJAX request before the response from the previous AJAX request has loaded. In this case, the client objects of your controls are not yet fully initializes when you initiate a new request.
If you are using AJAX, you need to make sure that a new request is initiated only after the previous has completed. The user can be notified of an ongoing AJAX request through the use of loading panels (e.g. RadAjaxLoadingPanel).

Veli,
Thanks for the response. I already have it linked to an ajaxloading panel and the loading panel dissapears before the controls are completely rendered in the MasterTableViewEditForm. Is there a way to make the AjaxLoadingPanel show until it has completely finished. The code sample I gave was just a "Play" code sample. I can give a production sample if you like. Thanks again for all the help.
Thanks,
Jonathan Adkins

Hi Jon,
If you can paste some sample code I can include in a project and run, I will be happy to look at this issue. Please, remember to provide the exact steps needed to reproduce the javascript errors you are getting.
If not, you will need to open a regular support ticket with an attached runnable project, so that we can be of better assistance to you. Please try to strip the project down to a minimum, so that the project best concentrates on reproducing the issue.

I have the same error.
Our Scenario.
A Page1.aspx with a RadGrid and AjaxManager. When you click edit on Grid1 we open a RadWindow based on a UserControl1.ascx this user control is an edit form. On this edit form Usercontrol1.ascx we have a UserControl2.ascx this 2nd control contains a Grid2 that uses a time picker with inline editing. When we try to edit the Grid2 we get the same error as described above and the DatePickers and RadComboBox in the inline editor do not work.
Please Help.

Hi Rory,
We may need to look at your particular scenario to be able to identify what exactly is causing this issue. Consider opening a regular support ticket where you can send us some sample code or, ideally, a small runnable project we can debug locally. In the mean time, you may want to look for possible javascript errors on page. Also, note that, as previously mentioned, you need to make sure any pending AJAX requests finish completely before you interact further with the page.

Hi Veli,
I can look into making a working project and opening a ticket but that will take a few days. I know that the error is coming from the use of a RadWindow to open a UserControl.ascx that contains a Grid with TimeDatePicker. I tried turning off Ajax and the error is still there. I turned off the DatePicker and the error stopped but this is not good since we need the Picker. I've pasted the error and section of code in Telerik that is broken. Let me know if have any other ideas? Perhaps a RadWindowManager setting?
Thanks.
The error:
"Line: 6517
Error: 'this.get_timeView()' is null or not an object"
The Telerik Code piece:
{var a=Telerik.Web.UI.RadDateTimePicker.TimePopupInstances[this.get_timeView().get_id()];

This error usually occurs when you have multiple RadDateTimePicker or RadTimePicker controls on the page and they are using a shared TimeView. If the shared time view is not AJAX-ified together with the pickers, you are getting this error after an AJAX postback. This is usually an AJAX-specific scenario and should not be reproducible with disabled AJAX. If you have completely disabled AJAX so that the page always makes full postbacks, and you are still getting this error, then the cause for this may lie elsewhere. In any case, we would not be able to suggest much without being able to reproduce this issue in your particular scenario. A live URL you can provide us may also help identify the cause for this.

Hello,
We discovered that our error is because we were using an HTA to view our application it appears HTAs and Iframes have issues and RadWindow uses an iframe container. We did however work around the error by using a GridTemplateColumn that contains a RadDateTimePicker instead of using the GridDateTimeColumn.
Thanks for the help.
