Hi!

In ASP.NET 4, the editor blanks its value in a postback when there are server-side validators on the page.
Simple example:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="test.aspx.vb" Inherits="test" %>
 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <asp:ScriptManager ID="ccc" runat="server">
    </asp:ScriptManager>
    <div>
        <telerik:RadToolBar ID="rtb" runat="server" AutoPostBack="True">
            <Items>
                <telerik:RadToolBarButton id="rtbb" runat="server" Text="Do postback">
                </telerik:RadToolBarButton>
            </Items>
        </telerik:RadToolBar>
        <asp:ValidationSummary ID="ValidationSummary" runat="server" />
        <telerik:RadEditor ID="re" runat="server">
        </telerik:RadEditor>
        <asp:TextBox ID="txt" runat="server"></asp:TextBox>
        <asp:RequiredFieldValidator ID="rfv" runat="server" ControlToValidate="txt" EnableClientScript="false"></asp:RequiredFieldValidator>
    </div>
    </form>
</body>
</html>
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!!!

Rikard

Hello Caesar,

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.

Hi Caesar,

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.

Hi Michael,

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.

I am using the latest released RadControls for ASP.NET AJAX (2011.1.413.40) and it appears that the problem has resurfaced of the RadEditor losing its value on postback in IE9 only. If i use FireFox 4, Chrome 10 or even Internet Explorer in compatibility mode, the RadEditor keeps its value.

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!

answered on 25 Apr 2011, 03:29 PM

Hello Brian Levin,

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.

This was the work-around suggested to me by Telerik:

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.

answered on 10 Jul 2013, 06:24 AM

Hi Igor,

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:

Looking forward for your reply.

Hi Igor,

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.

Hi Igor,

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

Hello Igor,

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.

Hi guys, this problem definitely exist and only in IE under certain conditions. My scenario is with RadAjxManagerProxy. If I remove the AjaxSetting for the RadButton and RadEditor the issue goes away but of course I loose parts of the page on postback. The weird thing is that I have similar pages without issue but those pages only have one or two AjaxSettings whereas this one have five. It would be nice to fix this but I guess I can rollback to Q2 2013 as it seems to have started when I upgraded to Q3 2013. Thanks. Daniel.

Hello,

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.

Hi Igor,

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.

Hi Rikard,

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.
