RadEditor 6.6.3 and Firefox 6.0

[MailUp Dev]

Hi to all, I've got problem rendering editor tool with the latest version of Firefox (6.0): all the tools buttons are missing and there is only a text area.
I tried a test page with only the editor but the result is the same.

Have you got some idea to resolve this problem?

Thanks in advance.

Hi,
I am having exactly the same issue, but with RadEditor 6.6.1
Any thoughts would be greatly appreciated!

Regards,

David

We're having the same problem :-/ Is any workaround available?

Same problem here. I have seen the plain text box version before, it is the graceful degradated version of the editor, that typically appears when the browser version is too old to support the rich text editor. So my theory is the new Firefox 6 browser info falls outside the range which the editor code can understand? Therefore it's defaulted to not-supported category.

This one is the Browser Info from Firefox 6
Browser CodeName: Mozilla
Browser Name: Netscape
Browser Version: 5.0 (Windows)
Platform: Win32
User-agent header: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:6.0) Gecko/20100101 Firefox/6.0

This one is from Firefox 3.6, where the editor still displays fine
Browser CodeName: Mozilla
Browser Name: Netscape
Browser Version: 5.0 (Windows; en-US)
Platform: Win32
User-agent header: Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.9.2.12) Gecko/20101026 Firefox/3.6.12

It's probably like cecilUOA said, after some test I discovered that if you change your UserAgent string with a FireFox add-on the editor works perfectly.

FireFox 6.0: Mozilla/5.0 (Windows NT 6.1; rv:6.0) Gecko/20100101 Firefox/6.0

In this way "Mozilla/5.0 (Windows NT 6.1; rv:5.0) Gecko/20100101 Firefox/5.0" things return to work.

Same problem here. Has someone found a server-side workaround? Changing the user-agent isn't an option.

[Carlo]

Same problem here. This editor on a MAC is actually no more usable other than with the old Firefox 3.6. A fix is urgently needed from Telerik, please help.

Same problem with  RadEditor v 7.3.2. Seems like a problem in browser detection script embedded as resource in editor dll.

Hi everyone,

I posted a sticky note today in RadEditor Classic forum about the problem and how to resolve it. Here it is: RadEditor for ASP.NET does not work properly in Firefox 6.

Hi Rumen,

Your solution does not solve the problem for our RadEditor.NET2 6.5.0 as there the DLL is obfuscated and therefore the private fields
_browserCapabilitiesRetrieved AND _isSupportedBrowser don't exist.

Could you please supply us with the correct field names for the 6.5.0 build.
That would save us a huge amount of time updating 50+ projects from 6.5.0 to a later 7.x version for which the workaround does work. As an update involves not only the DLL update but also updates for config- and toolsfiles, js script folders and checking every project does still work.

Tnx,
Jan-Pieter

Hello, How can we implement this fix if we are using the installable DNN version of the editor? Do we need to modify it in the source?

[Rumen]

Hi Jan-Pieter,

If you use RadEditor.Net2.dll v.6.5.0 you should replace

_isSupportedBrowser with _xe6281f3f95a41c0f

_browserCapabilitiesRetrieved with _xa49ae9b39666c916

e.g.

System.Reflection.FieldInfo browserCheckedField = typeof(RadEditor).GetField("_xa49ae9b39666c916", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);

browserCheckedField.SetValue(RadEditor1, true);

System.Reflection.FieldInfo browserSupportedField = typeof(RadEditor).GetField("_x0718e97515adc940", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);

browserSupportedField.SetValue(RadEditor1, true);

Kind regards,

Hi Joseph,

You should modify the RadHtmlEditorProvider.vb DNN provider code.

Dear Rumen,
actually we had to test the Request.UserAgent value rather than the Request.Browser.Browser but besides that everything worked.

Thanks,

[J-P Minderhoud]

Hi Rumen,

Although I do believe that these are the correct fields the fix does not seem to work.
The fields are correctly set to 'true' and remain 'true' throughout the editor's life cycle, according to the test code below, but still only a text-area is rendered.

Thanks,
Jan-Pieter

PS: The 'normal' workaround does work for our projects running the 7.x RadEditor

namespace RadEditor65Firefox6Test
{
    public class TestEditor : Telerik.WebControls.RadEditor
    {
        private void AssertIsBrowserSupported()
        {
            System.Reflection.FieldInfo browserCheckedField = typeof(Telerik.WebControls.RadEditor).GetField("_xa49ae9b39666c916", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
            var browserChecked = (bool)browserCheckedField.GetValue(this);
            System.Reflection.FieldInfo browserSupportedField = typeof(Telerik.WebControls.RadEditor).GetField("_x0718e97515adc940", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
            var browserSupported = (bool)browserSupportedField.GetValue(this);
            System.Diagnostics.Debug.Assert(browserChecked == true, "browserChecked FALSE");
            System.Diagnostics.Debug.Assert(browserSupported == true, "browserSupported FALSE");
        }

        protected override void OnInit(EventArgs e)
        {
            if (this.Context.Request.Browser.Browser.ToLowerInvariant() == "firefox")
            {
                System.Reflection.FieldInfo browserCheckedField = typeof(Telerik.WebControls.RadEditor).GetField("_xa49ae9b39666c916", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
                browserCheckedField.SetValue(this, true);
                System.Reflection.FieldInfo browserSupportedField = typeof(Telerik.WebControls.RadEditor).GetField("_x0718e97515adc940", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
                browserSupportedField.SetValue(this, true);
            }
            base.OnInit(e);
            AssertIsBrowserSupported();
        }

        protected override void OnLoad(EventArgs e)
        {
            base.OnLoad(e);
            AssertIsBrowserSupported();
        }

        protected override void Render(HtmlTextWriter output)
        {
            AssertIsBrowserSupported();
            base.Render(output);
            AssertIsBrowserSupported();
        }
    }
}

Hi Admin,

I have many website using old RadEditor,

so do you know these information

_isSupportedBrowser with _xe6281f3f95a41c0f

_browserCapabilitiesRetrieved with _xa49ae9b39666c916

for RadEditor v5.5.2 ?

Thank you very much :)

[Dave]

We're using DNN 4.7 and RadEditor.Net2 v 7.2.1. These fixes are not working. Is there something else we need to do for this version? Or are the fields different?

Thanks!

[Jian]

Hi Rumen,

I am using RadEditor 6.0.1.0, and your solution didn't work with my editor.

Is there anything specific that I should do with this version of RadEditor?

Thanks in advance.
Jian

Hi guys,

The development and support of RadEditor Classic is discontinued since 2009 and we could not provide further help for the versions prior 7.x.x, because their code is obfuscated and will require precious time to provide a working solution for each separate version, time that we can use to implement new controls, features and fix bugs in the new Ajax suite. You can find information about Telerik's Support Lifecycle Policy in this article: Telerik's Support Lifecycle Policy and see the following chart: http://www.telerik.com/libraries/ajax_product_pages/radcontrols-lifecycle.sflb.

There is no general solution for the versions prior 7.x.x and our recommendation is to consider migration to the latest classic build 7.3.6. It does not support officially the modern browsers, but still can work under them using different workarounds.

The recommended approach however is to migrate to the new and much enhanced RadEditor for ASP.NET AJAX, which officially supports all new browsers and offers multiple new features and bug fixes compared to its predecessor.

Best regards,
Rumen

Hi !

Take a look at this website: http://metatips.webs.com/apps/blog/show/8209076-radeditor-telerik-firefox-6-probleme-de-compatibilite-radeditor-for-asp-net-does-not-work-properly-in-firefox-6

Here, the default value was changed but you can try to change the regex. It will be better....

Good luck ;)
