Hi,

I am facing an issue with RadAjaxManager when I do 2 back-to-back Ajax calls. Attached is the image of what is shown in place of the update panel.

Following is how my project is setup.

1. Master Page has RadAjaxManager and LoadingPanel. Let's call this page 1

2. Page 2 uses Page 1 as it's MasterPage. Page 2 also has Dynamic Viewer loader which loads multiple .ascx extension pages.

3. Page 3 and Page 4 are those .ascx pages with the controls we need to apply RadAjaxManager on.

Now I am not able to access RadAjaxManager of Page1 from page 3 and 4. So I add the individual RadAjaxManagers to page 3 and 4.

They work fine for the first Ajax call.

If I do another Ajax call without a postback in between, it gives me a blank screen with the message as in the image in place of the UpdateControl.

Can someone please guide me how to fix the issue?

Thanks in advanced,

Hi

We have Batch editable grid with GridBoundColumns and GridTemplateColumns because of need checkbox / combobox. Some columns are editable and some read only by default or set read only by user rights to do changes (on page loading events set column to readonly). All possible changeable columns are set to ForceExtractValue="true" that those are available on ObjectDataSource updating event parameters. But when GridTemplateColumn is changed to readonly, value is not there anymore. What we do wrong?

Here is aspx file columns both normal (and always readonly column) and template column (changed code behind to read only):

Here are couple different users run situation for same row from ObjectDataSource OnUpdating event.

Event code from where debug watch compare lists:

Result from debug watch (some formatting to show properly) with user where all are enabled:

And result with user where that approvalcheckpoint column is read only (compare rows 5 and 8 to above):

Hi

I have a inherited class of RadTreeView with TreeNodeExpandMode set on ServerSideCallBack.

I will save the RadTreeView's expanded nodes using RadPersistenceManager. 

I set ControlID on RadPersistenceManager at server side

CookieStorageProvider is the class of this example: https://demos.telerik.com/aspnet-ajax/persistence-framework/examples/custom-storage-provider/defaultcs.aspx

I use two button to save/load state

When I save a state I receive only this code

Where am I doing wrong? Why am I not getting the status of the RadTreeView?

I use Telerik Ajax Q2 2012.

Thanks

I am using 2015.3.1111.40.

I just find out that my server is attacked with CVE-2019-18935.  There are many applications that are running the v 2015.  I used both the old upload and the async upload, the editors etc.

I read this:

https://www.telerik.com/forums/security-vulnerabilities-cve-2017-11357-cve-2017-11317-cve-2014-2217-safe-if-we-don't-use-radasyncupload-control

Is this CVE-2019-18935 the same vulnerability ?I  want to fix it and will like to know

1. I need to download the patch from my account. Just replace the Telerik.web.UI.dll ?

2. Do I need to add those keys as mentioned in the last link?

<add key="Telerik.AsyncUpload.ConfigurationEncryptionKey" value="YOUR-FIRST-UNIQUE-STRONG-RANDOM-VALUE-UNIQUE-TO-YOUR-APP&" />

<add key="Telerik.Upload.ConfigurationHashKey" value="YOUR-SECOND-UNIQUE-STRONG-RANDOM-VALUE-UNIQUE-TO-YOUR-APP&" />

<add key="Telerik.Upload.AllowedCustomMetaDataTypes" value="Telerik.Web.UI.AsyncUploadConfiguration" />

3. As there are quite many web sites.  Is there a way to globally apply the keys? eg. in the IIS root folder?  Actually the server can be only accessed by me.

Thanks.

Hi,

I have setup an application like the example shown to replace the edit form of the appointment.

In AdvancedForm user can enter data and save by clicking a button.

While that doesn't clos the AdvancedForm I set the OnClientClicked property of that button to call a js.

The AdvancedForm will be closed and for a short time there is a busy sign. But the scheduler doesn't update the display (new appointments doesn't appear).

When refreshing the scheduler (F5) the appointment will be displayed.

Before I had set the OnClientClicked methode and closing the AdvancedForm manually scheduler update was ok.

My script in AdvancedForm.ASPX is like that:

function btnSpeichern_Clicked(sender,args)
    {
        window.close();
}

The script from the scheduler is

            function refreshScheduler() {
                var ajaxManager = $find("RadAjaxManager1");
                ajaxManager.ajaxRequest('RebindScheduler');
            }

These function will be executed when closing the AdvancedForm. But the display is not correct (new appointment is missing or updated appointment shown as before).

Any idea?

Regards

Hi!,

TargetFramework: 4.5.2

DLL from C:\Program Files (x86)\Progress\Telerik UI for ASP.NET AJAX R2 2020\Bin45

Starting first default page debugger in Visual Studio give me Exception Unhanded: DOMException: Failed to execute 'querySelectorAll' on 'Element': '*,:x' is not a valid selector. Visual stop just after comment below (Please check attachment).

Also loading pages is slow. Maybe because this exception occurs 2 times per each page (on loading).

Page is simple:
