[Harry]

Hey Gents,

I am having a problem getting the Image Manager dialog to work. All buttons are disabled on Image Manager dialog except Refresh button works. my code below:

                                <rad:RadEditor ID="ctl_txt_Body" runat="server" Width="500px" Height="400px" SkinID="DefaultSetOfTools"

                                    <ImageManager ViewPaths="~/Img" UploadPaths="~/Img" DeletePaths="~/Img" />
                                </rad:RadEditor>

I am using this version assembly: Telerik.Web.UI.dll Product version is 2008.03.1125.35

    <handlers>
      <add name="Telerik.Web.UI.SpellCheckHandler.axd_*" path="Telerik.Web.UI.SpellCheckHandler.axd" verb="*" type="Telerik.Web.UI.SpellCheckHandler, Telerik.Web.UI, Culture=neutral, PublicKeyToken=121fae78165ba3d4" preCondition="integratedMode,runtimeVersionv2.0"/>

    </handlers>

The environment is Win 2008 + IIS 7 + .NET 3.5, Managed Pipeline Mode is Classic. I gave the write permission to Network Service. It doesn't work for me when tried many post about image manager disabled in the forums. Could you tell me what I am doing wrong please?

Looking forward to hear from you soon.

Thanks,
Harry

Hi Harry,

If you have tried all the instructions provided in this KB article: Uploading images to the server (upload tab is disabled) and you are still unable to enable the Image manager, then please open a support ticket and send a sample working project along with screenshot showing your project structure in IIS.

Hi Rumen,

Thank you for your answer. I attached the screenshot first. got the js errors in IE8. does these useful for you to figure it out?

Best Regards,
Harry

[Harry]

Hi Rumen,

This is js errors in IE 8. And The buttons of Image Manager are disabled in FireFox 3.5.5 and IE8 Compatibility View/IE7 though doesn't raise any js error.

i'm going to try 2009.1 402 build for IE 8 issue.

Could you tell me why i got this error after upgrating to the latest version?

Version: 2009.3 1208

Server Error in '/' Application.
--------------------------------------------------------------------------------

Security Exception
Description: The application attempted to perform an operation not allowed by the security policy.  To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Hi Rumen,

I just found that it doesn't work on page with form Authentication, but the buttons enabled on public page without any Authentication.

any ideas?

Thanks,
Harry

[Rumen]

Hi Harry,

In form authentication scenario a non logged user is redirected to the login page. When a non user load some dialog then the code tried to load the login screen in the dialog, but the dialog expects other content and throws the reported error.

The DialogHandler must be always accessible and to fix the problem you should add the following two <location> entries to the web.config:

<location path="Telerik.Web.UI.DialogHandler.aspx">
    <system.web>
        <authorization>
            <allow roles="TestUser"/>
        </authorization>
    </system.web>
</location>
<location path="Telerik.Web.UI.SpellCheckHandler.axd">
    <system.web>
        <authorization>
            <allow roles="TestUser"/>
        </authorization>
    </system.web>
</location>

All the best,

Hi Harry

I also have Same Problem......
i read almost all articles finally i find the solution analyzing them.
i.e We need to add  AllowScripts="True" in radeditor Markup.
Example:

<telerik:RadEditor ID="BodyText" SkinID="BasicSetOfTools" runat="server" Height="400" DialogHandlerUrl="~/Telerik.Web.UI.DialogHandler.axd"
                        Width="860px" EnableResize="true" AllowScripts="True">
<ImageManager UploadPaths="~/img" ViewPaths="~/img" MaxUploadFileSize="10240000"  SearchPatterns="*.gif, *.jpg, *.jpe, *.jpeg, *.tiff, *.tif,*.bmp"/>
</telerik:RadEditor>

**Very Important
don't forgot to add handler file in web.config file

<httpHandlers>
            <add path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" validate="false"/>
            <add path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" verb="*" validate="false"/>
            <add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false"/>
            <add path="Telerik.Web.UI.DialogHandler.axd" type="Telerik.Web.UI.DialogHandler" verb="*" validate="false"/>
        </httpHandlers>

and

<system.webServer>
    <!--<modules runAllManagedModulesForAllRequests="true"/>-->
    <validation validateIntegratedModeConfiguration="false"/>
    <handlers>
        <add name="Telerik_Web_UI_DialogHandler_aspx" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler"/>
        <add name="Telerik_Web_UI_SpellCheckHandler_axd" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler"/>
        <add name="Telerik_Web_UI_WebResource_axd" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource"/>
        <add name="Telerik_Web_UI_DialogHandler_axd" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.DialogHandler.axd" type="Telerik.Web.UI.DialogHandler"/>
    </handlers>
</system.webServer>

This Code Solve My Problem.
Now I can Add Image through Image Manager.

Hi Rumen,

Tried with changes but still upload , Refresh are disabled ,Can anyone help on this?

[Rumen]

Hi Kumar,

It looks like that the path set in the ViewPaths property actually works since the folders are loaded in the Image and Docs manager. Check out whether the same path is set for the Upload and DeletePaths and that they have full NETWORK SERVICE account permissions.

The ViewPaths, UploadPaths and DeletePaths properties should point to a folder that is:

• a subdirectory of your web application
• a directory placed in the root of IIS - you can set this folder by using the / forward slash symbol, e.g. ViewPaths = " /Files ";
• a virtual directory of your web application that has a physical path pointing outside of your web application.

See this article for more info: Enforcing Roles.

You can also check the applied permissions programmatically with the sample at https://docs.telerik.com/devtools/aspnet-ajax/controls/fileexplorer/troubleshooting/common-issues#an-error-like--because-the-application-did-not-have-enough-permissions-occurs-only-in-a-production-environment-how-to-debug-the-issue.

Checked the permissions as well and given access to users but still issue exists.

 <ImageManager 
        ViewPaths="~/files/Uploads/Images" 
        UploadPaths="~/files/Uploads/Images" 
        DeletePaths="~/files/Uploads/Images"
MaxUploadFileSize="5242880"
        SearchPatterns="*.gif,*.jpg,*.jpeg,*.png,*.bmp" 
        ViewMode="Grid" />
    <DocumentManager 
        ViewPaths="~/files/Uploads/Documents" 
        UploadPaths="~/files/Uploads/Documents" 
        DeletePaths="~/files/Uploads/Documents"
MaxUploadFileSize="51200000"
        SearchPatterns="*.doc,*.docx,*.xls,*.xlsx,*.ppt,*.pptx,*.pdf,*.zip,*.ics,*.vcf" />

Hi,

Your configuration looks perfect.

Check for any JS errors in the console.

Also test the latest version of the control R1 2021 SP2 and in a brand new project to see if it is not due to the configuration of the current project.

Hi While clicking those Image manager and Document Manager,getting this issues in Console.

 

[Rumen]

Since these errors do not look Telerik related (the ScriptResource.axd handler is from the WebForms framework, but not Telerik) please resolve them and once resolved test the dialogs. 

Also check whether you are using the  ASP.NET AJAX Control Toolkit Script Manager, which is not supported by the Telerik controls.

Hi Rumen,

I have tried to resolve, Tested with document mode IE7,issue resides. When we change document mode to IE8 in Internet Explorer ,then all the tabs are enabled both in Image , Document manager.

Currently we are using 2020.3.915.45 with .NetFramework 4.8.

Is there any compatibility issue with .Net framework4.8 for this issue?

 

[Rumen]

Hi Kumar,

This is a good catch!

The compat mode of IE is not supported as noted at the Browser Support page as well as in these articles:

• Disable the Compatibility View mode of Internet Explorer
• Different appearance or behavior in Internet Explorer on local and production servers

Rumen

[Sachita]

Thanks for the help.

1.We are using trail hotfix to test the application, and trail is expired, will it be the issue for tabs not working?

2.Is Document mode IE7  not compatible with Telerik R3 2020.3.915.45?

3..Is the Telerik version 2020.3.915 compatible with .Netframework 4.8 or .Netframework 3.5?

4.Can I get any article related to compatibility upto latest Telerik version?

Can you please help me to know about information.

[Rumen]

Hello,

Straight to the questions:

1. The trial version is fully functional and the only difference with the registered developer's one is that it throws random license errors in the browser. The trial version will continue to work even after the trial gets expired, but you will not be eligible for free support.
2. IE7 and IE Compatibility Mode, which triggers IE7 emulation are not supported as of R3 2015. This means that R3 2020.3.915.45 does not support it too.
3. Yes, R3 2020.3.915.45 supports both .NET 3.5 and .NET 4.8. See more at https://www.telerik.com/aspnet-ajax/tech-sheets/net-support. 
4. Along with the page provided in point 3, you can also check this one: https://docs.telerik.com/devtools/aspnet-ajax/licensing/old-versions-support-policy.
