RadEditor <rade:radeditor> control not rendering properly in firefox works fine in IE and Chrome

[Manaswi]

<rade:radeditor> control is not rendered properly in Firefox where it's working fine in IE and Chrome. Observed one thing by comparison with other browsers is that the functions which are in radEditor.js are hitting fine for other browsers but not Firefox. In Firefox we can see it's only hitting starting point in js file after that it's not hitting functions like RadEditorInitilaize() etc..Please respond as soon as possible.

Hi Manaswi,

Can you please send a screenshot of the error in the console of Firefox? You can also share the RadEditor configuration and the page where it resides.

Is the editor placed in RadWindow ContentTemplate? If yes, follow the steps to fix the problem in this article https://docs.telerik.com/devtools/aspnet-ajax/controls/window/troubleshooting/radeditor-does-not-work-in-radwindow.

Thanks for the quick response Rumen.

Attached screenshot of Firefox issue where 1st issue(this.Window.document.body is null) is common among all browsers where as second issue is only in Firefox. After commenting code RadEditorCommandList also i don't see any result. 

Used as below

<rade:radeditor OnClientLoad="OnClientLoad" id="DimCommentsEditor" style="LEFT: 1px; TOP: -24px"
CssClass="TelerikTest" SaveInFile="False" Font-Size="Smaller" ShowPreviewMode="False" ShowHtmlMode="False"
Runat="server" Editable="True" ShowSubmitCancelButtons="False" OnClientCommandExecuting="OnClientCommandExecuting"
EnableDocking="False"></rade:radeditor>

 

Here this popup opens up from some window where it's not rendering properly.

We did not use any RadWindow ContentTemplate. Just used radEditor control.

Thank you for the screenshot!

Now, I see that you are using RadEditor Classic (RadEditor.dll or RadEditor.Net2.dll) part of the RadControls for ASP.NET suite which was discontinued in 2009 in favor of Telerik UI for ASP.NET AJAX (Telerik.Web.UI.dll).

RadEditor Classic does not support the latest version of Firefox and the only way to get support for all modern browsers including Firefox is to migrate to RadEditor for ASP.NET AJAX (part of Telerik UI for ASP.NET AJAX).

You can find migration instructions on Migration from RadEditor Classic to RadEditor for ASP.NET AJAX.

We are facing issue in Internet Explorer.As above said we are using Rad Editor Classic and we have observed below.

Details of both Machine 1 and Machine 2:

Windows 10 OS

IE version -- 11

 

On Machine 1 Rad Control loaded properly

On Machine 2 with same configuration of Machine 1 Rad control is not loading and giving error as shown in screenshot.

In order to resolve this issue in IE I have added radEditor.js script in popup page as well(where this radEditor should be displayed as shown in screenshot), where we have opened this page from other page where radEditor.js is already included in that aspx page(Main.aspx).Without adding this js file in popup page working fine in Chrome only.So in order to work in IE I have added in popup page again that js file.So works in Machine1. When it comes to machine 2 same code not working for IE. Please let us know what could be the issue.

We could see as same in Firefox for IE also it's not hitting functions in radEditor.js file in Machine2.

Hi again,

I am not sure what are the contents of this radEditor.js file and how it helps the editor to work fine on one of the machines. I am also not sure what are the differences between these two machines.

The problem could be due to that the IE browser on the first one works in Compatibility mode and in the other in the standard mode. There might be also a JavaScript error.

It is important to say that RadEditor Classic is built in 2009 (its latest version) and it does not support officially IE11 which was released on October 17, 2013 (four years later). That's why I strongly recommend you to migrate to RadEditor for ASP.NET AJAX which is supported and works as expected in all browsers.
