Scenario

• The page has a left navigation panel that can be collapsed / expanded

• On toggle, the main content container width is changed using CSS only (no page refresh)

• On initial page load or full refresh, the grid renders correctly

• On toggle of grid button in the expand mode only, the grid suddenly shows a horizontal scrollbar

Observed Behaviour

• This happens only after clicking toggle ( external button written in C# code)

• Rebinding the grid (Rebind()) or calling repaint() does not fix the issue

• A full page refresh always fixes it. 

How can i prevent the scoll from appearing when the grid has lesser columns. the scrolls appears from _Frozen.

Css used for toggle small -> condensed , and condensed -> small 

.small .RadGrid .rgRow td,
.small .RadGrid .rgAltRow td,
.small .RadGrid .rgEditRow td,

.small .gridFillLayoutPanel .RadGrid_Metro .rgHeader th,
.small .gridFillLayoutPanel .RadGrid_Metro .rgGroupHeader th,
.small .RadGrid .rgRow > td,
.small .RadGrid .rgAltRow > td,
.small .RadGrid .rgEditRow > td,
.small .RadGrid .rgFilterRow > td {
    padding-left: 8px !important;
    padding-right: 8px !important;
    line-height: 32px !important;
    height: 32px !important;
    font-family: @font-tab-title;
    font-size: 12px;
    padding-top: 7px !important;
    padding-bottom: 7px !important;
    text-align: left;
}

I downloaded the trial version of DevCraft and am using the license key in my .NET application. Tried adding the license both ways -

- NuGet Telerik license

- Copy the script to .cs file

But I see the same error on running the application.

Could not load file or assembly 'Telerik.Licensing.Runtime, Version=1.6.31.0, Culture=neutral, PublicKeyToken=98bb5b04e55c09ef' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

RadWindow is a great control and it's very usefull.

The issues start when the UI inside gets more complex, and requires javascript to deal with interactions on client side instead of server side.

The RadWindow control is placed inside a parent element but when it opens, all the contents get relocated into the DOM root causing a problem with event listeners, element finding among other headaches.

Testing with your Telerik Web UI Window Content Template Demo | Telerik UI for ASP.NET AJAX demo, moving the generated window element "RadWindowWrapper_ctl00_ContentPlaceholder1_UserListDialog" inside its original element  "demo-container", kept the demo working perfectly with no side effects.

So, the question is, why are you moving the contents of a RadWindow to the DOM root causing so many problems for those who need to create complex UIs inside the window? Can't you at least let the developer decide that with a parameter? 

Is there any way to avoid this behaviour, maybe using javascript?

Thank you.

Hello Telerik Support,

We are experiencing an issue with the RadGrid control when sorting by a single column that contains many duplicate values. The ordering of the results is inconsistent, which can confuse users. Additionally, in some cases, selecting a row causes the grid to re-sort unexpectedly, rather than navigating to the selected record’s page.

This behavior only occurs when sorting by a single column with non-unique values. When sorting by multiple columns, the ordering and navigation work as expected.

Could you please advise on:
• How to ensure stable and predictable sorting in RadGrid when sorting by columns with duplicate values?
• Best practices for maintaining consistent row selection and navigation behavior in these scenarios?

We are targeting .NET Framework 4.8.

Thank you for your assistance.

2025 Q4 Release strips inline base64 encoded image source by default. 

With the introduction of the new StripJavaScriptUris content filter that is enabled by default as part of the DefaultFilters,  we are seeing inline base64 encoded image source data completely erased. 

For example an image that looks like this:

<img src="data:image/jpeg;base64,/9j/4AAQSkZJRgABAAEAYABgAAD//gAfTEVBRCBUZWNobm9sb2dpZXMgSW5jLiBWMS4wMQD/...." />

becomes

<img src="" />

Is this the intended behavior for this content filter?   

I was able to correct this by adding the following attribute to my <telerik:RadEditor> tag:

ContentFilters="RemoveScripts,StripDomEventAttributes,EncodeScripts,StripCssExpressions,FixUlBoldItalic,IECleanAnchors,MozEmStrong,ConvertTags,ConvertFontToSpan,OptimizeSpans,ConvertToXhtml,IndentHTMLContent,ConvertCharactersToEntities,RemoveExtraBreaks"

Essentially its the same as DefaultFilters, minus the new StripJavaScriptUris.

Please advise...

WCAG Accessibility requires keyboard support, but the documentation doesn't show any support?

I realize this isn't a DNN forum, but couldn't find anything there so hoping someone here can answer.

After upgrading to DNN 9.11.3 several modules don't work right because DNN no longer supports Telerik.

I've read somewhere that you can purchase a Telerik license and just update the dlls for it in DNN in order to resolve this issue.

Has anyone else had this experience?

Thanks

What is the latest compatible Telerik.Web.UI version for .NET framework 4.7.2 that can address the security vulnerabilities. 

Current version used in the project is - 2012.3.1308.40

Looking to fix the following vulnerabilities -

CVE-2019-19790, CVE-2019-18935, CVE-2017-11357, CVE-2017-11317, CVE-2017-9248, CVE-2014-4958

I'm trying hide a couple of columns in a RadGrid. I can do this in RadGrid1_ItemDataBound with the GrdiHeaderItem setting visible = false.

However, the output still uses space for the 2 columns that were hidden at the end of the grid.

Looking at the page source when I run my app there are 2 extra <col /> tags in <colgroup> and the <tfoot> tag has 2 extra <td></td> tags. There is the correct number of <td> tags in each row in <tr> in the table body.

Could this be from css? Is there a way in override this in RadGrid1_ItemDataBound manually?

On our side the update to version 2025.4 is failing because of browser inlog issue, see attaches screenshot.

What to do?
