In ASP.NET 4, the editor blanks its value in a postback when there are server-side validators on the page.
Simple example:
Write something in the RadEditor. Then press the "Do postback" button. The RadEditor is blanked out! We hope this will be fixed really fast. Breaks our entire application!!! Regards Rikard<%@ Page Language="VB" AutoEventWireup="false" CodeFile="test.aspx.vb" Inherits="test" %>

Thank you for reporting this problem.
I verified it and logged it with very high priority in our PITS system. The problem is introduced in version 2010.2 826 (Q2 2010 SP1) and it does not exist in 2010.1.713 (Q2 2010). The problem is not reproducible with ASP.NET Button and I was able to workaround it using the code below:
<telerik:RadToolBar ID=
"rtb"
runat=
"server"
AutoPostBack=
"true"
OnClientButtonClicked=
"onButtonClicked"
>
<Items>
<telerik:RadToolBarButton id=
"rtbb"
runat=
"server"
Text=
"Do postback"
>
</telerik:RadToolBarButton>
</Items>
</telerik:RadToolBar>
<script type=
"text/javascript"
>
function
onButtonClicked(sender, args) {
if
(args.get_item().get_text() ==
"Do postback"
) {
$get(
"Submit"
).click();
}
}
</script>
<asp:ValidationSummary ID=
"ValidationSummary"
runat=
"server"
/>
<telerik:RadEditor ID=
"re"
runat=
"server"
></telerik:RadEditor>
<asp:Button ID=
"Submit"
style=
"display:none"
runat=
"server"
/>
<asp:TextBox ID=
"txt"
runat=
"server"
></asp:TextBox>
<asp:RequiredFieldValidator ID=
"rfv"
runat=
"server"
ControlToValidate=
"txt"
EnableClientScript=
"false"
></asp:RequiredFieldValidator>
Our developers will fix the problem as early as possible. Here you can find the PITS Issue: Public URL.

This is a follow-up.
After detailed examination we found that the problem is due to the EnableClientScript property set to false in the validator control. You should enable the client validation and this will fix the problem.
Greetings,
Rumen
the Telerik team

This is not an option for us.
In our real world application, we actually uses CustomValidators that can't be validated on the client.
The highly simplified sample I posted were only intended for you to locate the bug easily.
Waiting for the fix to land in the latest internal build...

Rikard
It appeared a bug in ASP.NET 4.0 Framework and the problem is also reproducible with earlier version of Telerik.Web.UI.dll. I managed to fix it by adding the AjaxControlToolkit.dll to the bin folder of the project. The AjaxControlToolkit overrides the ASP.NET AJAX scripts when added to the project and fixes the problem.
Greetings,
Rumen
the Telerik team

We are having the same problem and it is a major issue as we use the Rad Editor in numerous places in our application with validation that cannot be set to be handled on the client.
We also are using the AJAX Control Toolkit and we still have this issue! The error only seems to happen on IE. Google Chrome and FF work fine. Please advise.
Alex
Which versions of RadEditor and ASP.NET do you use in your application? Could you please open a support ticket and send a sample working project that demonstrates the problem?
Best regards,
Rumen
the Telerik team

The version of the AJAX toolkit that you supplied fixes the problem if it is in the Bin directory. We were using a more recent version of the AJAX toolkit in our application. We have switched to the AJAX toolkit .dll that you have supplied in this post.
Besides using the supplied AJAX toolkit dll, will Telerik be able to fix this issue in a future release?
Alex
If it is possible our developers will fix it.
Best regards,
Rumen
the Telerik team

What's the status for this?
We don't feel like start using an old version of Ajax toolkit (we are not using Ajax toolkit at all, and have no plans starting), so do you know if Microsoft will fix this soon or will your developers be able to fix it?
Kinda serious bug, since the entire value is cleared!!!
Regards
Rikard

I have good news that the problem was fixed internally and it will not exist in the upcoming Q2 2010 SP2 release. We are targeting a release date for the end of September 2010.

We are about to release today Q2 2010 SP2 of RadControls for ASP.NET AJAX. Please, test it once it becomes available for download under your Telerik account today / tomorrow and if you still experience any problems open a support ticket and send a fully working project that demonstrates them.
Best regards,
Rumen

I have a RadAjaxPanel on the page with a RadEditor and RadButton on the page. I enter some text in the RadEditor, click the RadButton. The RadButton's click event fires but the RadEdtior's Content property is always an empty string. Again this is only an issue with Internet Explorer 9. Any help would be greatly appreciated!
Could you please set the UseSubmitBehavior property of RadButton to "false", e.g.
<telerik:RadButton UseSubmitBehavior="false"
This should fix the problem. The problem is discussed in the following not so up-to-date KB article: RadEditor Content Not Saved After Ajax Update in Firefox, Google Chrome and Safari.

Browse the vast support resources we have to jump start your development with RadControls for ASP.NET AJAX. See how to integrate our AJAX controls seamlessly in SharePoint 2007/2010 visiting our common SharePoint portal.


We are experiencing this problem again but only with IE 9. If I put the browser in "compatibility view" the rad editor works fine. Please advise.
I downloaded the latest hotfix for the Rad Controls and the issue is still there with IE 9. Please advise.
Alex
Could you please open a support ticket and send a simple runnable project which we can examine and reproduce the problem on our end?

All you need to do to fix this ASP.NET problem is to set
UseSubmitBehavior="false"
to the Submit button, e.g.<asp:Button ID="btnSaveAdminFee" UseSubmitBehavior="false" ValidationGroup="ValAdminFee" runat="server" Text="Save Admin Fee" CssClass="AdminButton" onclick="btnSaveAdminFee_Click" />
The problem is described in the following KB article: http://www.telerik.com/support/kb/aspnet-ajax/editor/radeditor-content-not-saved-after-ajax-update-in-firefox-google-chrome-and-safari.aspx
-------------------------------------------------------------------------------------------------------------------------------------------------
I had javascript validation on the button before it should do a postback so they suggested the following code:
<script type=
"text/javascript"
>
function
ValidateAdminFee() {
//TELERIK: if validation passed invoke postback
if
(
true
) {
__doPostBack(
"<%=btnSaveAdminFee.UniqueID%>"
,
''
);
}
else
alert(
"Not Valid"
);
}
</script>
<asp:Button UseSubmitBehavior=
"false"
OnClientClick=
"ValidateAdminFee();"
ID=
"btnSaveAdminFee"
ValidationGroup=
"ValAdminFee"
runat=
"server"
Text=
"Save Admin Fee"
CssClass=
"AdminButton"
OnClick=
"btnSaveAdminFee_Click"
/>

Very similar problem for me with the last 2013.2 version.
I have a RadGrid with an HTML column that in edit mode renders automatically as a RadEditor.
When I use ExtractValuesFromItem to get the values during an InsertCommand event, it returns always an empty string. Well not always, only with Internet Explorer (9 or 10) and only on the production server (medium trust level).
- Firefox WORKS
- IE locally using ISS Express WORKS
- IE on remote production server BUG!
If I remove RadAjaxManager from the page, it starts working on IE too.
Could you please confirm that your page inherits the RadAjaxPage. It is a required as a base class for any page that hosts a RadAjaxManager or RadAjaxPanel control and runs under Medium trust privileges. More information you can find here:
http://www.telerik.com/help/aspnet-ajax/ajax-in-medium-trust.html
Looking forward for your reply.

The described issue is very strange. We have not encountered it so far and we are not sure what could be the reason for experiencing the problem. Could you please post your aspx page markup code with the related code behind file? Thus we will be able to gather more details about your scenario and provide you with more to-the-point answer.
Looking forward for your reply.

I tried to reproduce the describe disuse on my side but to no avail. I am sending you a simple example which demonstrates the described scenario. Also on the following link I attached a small video which demonstrates that the example works as expected on my side. Could you please check it out and let me know if when you host it on your side the described issue is appeared?
Also could you please try using the GridEditableItem.ExtractValues instead of GridEditableItem.OwnerTableView.ExtractValuesFromItem and let me know if the issue still persists.
Looking forward for your reply.

GOTCHA!
Thanks to your sample I found the real cause of the grid bug. Now it's your turn to solve it :D
- I don't think the cause is the medium trust level, in fact if I set medium trust level on my PC, it works.
- Using GridEditableItem.ExtractValues has no effect, the bug persists
- Your sample on my ISP server works
So I started commenting the tags of my page until it starts working and… the responsible are the validators.
Take your sample and simply change your ID column to
<
telerik:GridBoundColumn
DataField
=
"ID"
HeaderText
=
"ID"
>
<
ColumnValidationSettings
EnableRequiredFieldValidation
=
"True"
>
<
RequiredFieldValidator
ErrorMessage
=
"*"
Display
=
"Dynamic"
></
RequiredFieldValidator
>
</
ColumnValidationSettings
>
</
telerik:GridBoundColumn
>
It won’t work anymore on my ISP server.
You can see it yourself, I put your sample (with the validator) on the following link
http://www.tav-engineering.com/test/WebForm1.aspx
Remember that now the ID is mandatory
With Firefox and other browsers it works
With IE the Label1 is always empty.
For a double check, here's your sample WITHOUT the validator
http://www.tav-engineering.com/test/WebForm2.aspx
This one works with every browser
Indeed I verified that the described issue exists into the current version of our controls. However it is logged into our bug tracking system and our developers will start working on its resolution. Please excuse us for the temporary inconvenience. Additionally as a small token of gratitude for your involvement I have updated your Telerik points.
If you need further assistance, do not hesitate to contact us again.

It does not work in Version 2013.2.611.40.
If my Button is on the same UserControl, i get the content of the RadEditor but the SaveButton is on a masterpage and it calls through an interface the Update Method, all the control values are set except the RadEditor Value (Content Property). It works in FireFox and Chrome but not with IE9 (9.0.8112.16421).

Christian
The described issue is logged into our bug tracking system and I will increase its priority. However we cannot commit to an exact time frame in which this issue will be fixed. Please excuse us for the temporary inconvenience.

It is still not fixed, do you have any idea about when it can be fixed? I thought it comes with the Q3 Release but that was not the case.
Best Regards
Christian



Are you sure its working in Version 2013.2.717.40?
I came with the previous Version of yours 2013.2.611.40 as I wrote in the post. After the Q3 Release I went to the newest Version 2013.3.1114.40 so I skipped the Version of 2013.2.717.40. As I saw your post I decided to go back to 2013.2.717.40 but as I expected, it did not work at all.
It is kinda frustrating to carry on a bug for 6 months...
Best Regards
Chris
Could you please have a look at the following KB article - RadEditor Content Not Saved After Ajax Update in IE9, Firefox, Google Chrome and Safari? Have you tried the solution provided there and could you confirm that it's not working in your scenario? Another solution you may try is to fire the editor.saveContent() client-side method:
var
radEditor = $find(
"<%=RadEditor1.ClientID%>"
);
radEditor.saveContent();
radEditor.set_html(radEditor.get_html(
true
));
If none of the suggested solutions work for your case I suggest that both of you open a support ticket and send us the code of your implementation so we can test and debug it locally. Once we have your sample projects we will do our best to send you a solution as soon as possible.
Thank you for your patience and I am looking forward to receiving your reply.

The problem is easily reproducible as mentioned above in my previous posts
The only solution for me now is to invite my customers to use every browser except IE... not a good solution, but I'm still waiting for a fix.
If the problem is related to saving content of teh RadEditor withing AJAX enabled controls, I would suggest following the KB article provided by Joana. You can find there more information about this matter. If this is the case, I can assure you that this behavior is due to incompatibility issue of the AJAX requests under IE and unfortunately this comes from the browser. In such cases we are unable to resolve such matter, because we cannot change behavior that is provided by the browser.

The problem regards only IE used with a RequiredFieldValidator.
I provided an example to reproduce the bug in May 2013 and Radoslav (look some posts above) answered me that it will be solved.
I reached my college Radoslav. The mentioned bug has been planed to be resolved for the upcoming release of the Telerik UI for ASP.NET AJAX (2014 Q1 SP1) which will be available after the 2nd of April. I recommend trying the same scenario the after upgrading with the mentioned version.

I am having the same issue. We are using Visual Studio 2008 c# and Telerik 2010. I downloaded the ddl you posted and tried it in our program. We receive the following error when running the application with the AjaxControlToolKit.dll i downloaded.
Could not load file or assemolToolkit' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.

We are having the same issue. We are using Viual Stdio 2008 with c#. We are running Telerik 2010. I tried adding the AjaxControlToolkit.dll but we get this error when using the toolkit.
Could not load file or assembly 'AjaxControlToolkit' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.
All help extremely appreciated.
From the described behavior is more likely this problem to be related to the AjaxControlToolkit suite used and not the Telerik one.
If this is so, note that Telerik controls are built within the Telerik.Web.UI library. About matters related to the AjaxControlToolkit library it is suggested to ask in forums related to AjaxControlToolkit.
Nevertheless, the problem could be due to incorrect references in the VS project. You can try removing them and add them again via the VS context menu of the project.

Check out the Telerik Platform - the only platform that combines a rich set of UI tools with powerful cloud services to develop web, hybrid and native mobile apps.

This still seems to be an issue with Q1 2018 of the controls.
<telerik:RadButton ID="RadButton1" runat="server" CssClass="ButtonClass" Text="Update Telerik" UseSubmitBehavior="false" />
UseSubmitBehavior="false" is still required, otherwise the content is lost on postback.
The issue is not directly due to a malfunction of RadEditor. It is due to MS AJAX behavior and the solution provided in the RadEditor Content Not Saved After Ajax Update in IE9, Firefox, Google Chrome and Safari article is still up-to-date.
