Hi, I am facing an issue where the Document Manager pop-up window that appears when attaching documents disappears from the right-hand file settings menu when zooming out of the page in any browser.

The issue is also reproducible here: Official RadEditor By Telerik

Please see the recording for more information:- https://jam.dev/c/de662891-5a44-4419-8738-616672fbb7f8

Hello Telerik Team,

Our customers identified a few accessibility concerns related to the RadEditor Image Manager and Document Manager popup windows:

1. Keyboard Focus on Popup Activation
   When a user tabs to the Image Manager plugin and presses Enter, the popup window opens. However, keyboard focus does not automatically move into the popup. Instead, the user must press the Tab key again to shift focus manually.
   ➤ To meet accessibility standards, focus should move directly into the modal or popup when it appears. This ensures that keyboard and screen reader users can interact with the dialog immediately without navigating through background content.
2. Missing Dialog Roles and Labels
   The dialog containers ( see below ) currently lack appropriate accessibility roles.
   ➤ Each dialog container should include role="dialog".
   ➤ If the dialog has a visible title, it should also include aria-labelledby referencing the ID of that title element. This allows assistive technologies to announce the dialog context clearly.

Is there any way to fix these two issues?

Thanks,

Lan

 

Hi,

I need to restore the expanded state of a RadTreeList after a redirect. I am storing the expanded items in Session before the redirect. However, server-side expansion only expands the root, not the child items.

Can someone share a JavaScript example or approach to fully expand all previously expanded nodes by the user after a redirect using the stored session data?

If your approach works in Server Side, I will use it on my solution

Thanks team!

This is an example using server side, but it expands only the first root element (not sure why)

Hi,

The OK and Cancel buttons of Image Map Editor are not properly visible in French (France).

I have attached a screenshot.

I cannot seem toe get my XAxis right with the following code, I simply want to display whole hours on the X-axis and values coming from a dataset like so

.

 

 <XAxis DataLabelsField="datum" Type="Category" Name="category" AxisCrossingValue="0" Color="black" BaseUnit="Hours" BaseUnitStep="1">
    <LabelsAppearance Visible="true" RotationAngle="45">
     </LabelsAppearance>

This produces the XAxis as shown in the attached screenshot.

What is the way to go?

 

 

Greetings,

I have noticed today that the following demo pages are broken when using the latest versions of Chrome & Edge:

Hi,

I am new to the Telerik, I have big story to ask, first I installed the Version=2016.1.113.35 on my Local machine, and started using the application everything was working good, before that I had different Version=2015.2.623.45 of Telerik on the same machine on top  of it I installed the current Version=2016.1.113.35. But when I deployed it on the Server, and server has the older version= 2015.2.623.45 that I had on my machine. And on the Server Telerik controls stopped working like RadEditor was completely disabled. 

Then I did some crazy mistake, I tried to manually copy the dlls of the same Version from Server and added them in to References thinking that this will work as backward compatibility would exist. Now it started giving me different Compilation errors. I am little frustrated can somebody please help me in this regards.

 My errors are as below:

<pre>

I Upgraded from ASP.net AJAX perpetual license to Dev Complete subscription and am running into ASP.NET AJAX License Error Banner & Watermarks issue. I have tried several approaches, but unable to solve the issue.

• Running a Web Application that is set to .net 4.7.2
• I installed Telerik 2025.3.825.462 and Telerik.Licensing.Runtime
• Copied the License vb script for UI for ASP.NET AJAX and pasted to top of assemblInfo.vb, the rebuild the project.
• I still get the banner. I have also tried copying the license.txt file to AppData\Roaming\telerik
• Also tried to Copy the VB code snippet into a new file, for example, TelerikLicense.vb and add to my project.
• I have tried removing .bin and .obj folders then rebuilding

Nothing is working. One odd thing I did notice is my VB Script License Key has 2 Assembly: Telerik.Licensing.EvidenceAttribute entries. In all of the Tutorial videos I have watched they only have 1 Assembly Entry.  Could one of these entries be my old perpetual license? Please advise what other steps I can try to troubleshoot.  

On my pageI have a RadGrid with columns containing gross and net ammounts  and a RadButton "Gross/Net". By clicking the button the grid shows it columns accordingly. Worked liek a charm.

Then I added aggregates od type "Sum" and still everything worked fine.

After that I added an aggregate od type "Custom" to one of the columns (which calculates  and shows everything as it should) but than I lost the button funcionality, clicking it does not switch the columns visibility. 

The button does:  myGrid.MasterTableView.GetColumn("mycolumn").Display = Not mybutton.Checked.
Also tried:  myGrid.MasterTableView.GetColumn("mycolumn").Visible = Not mybutton.Checked
