When assigning multiple resources and percentages, the first item in list always goes back to 100%.
It saves back to UI correctly but as soon as you leave or refresh page it goes back to 100% on first item and that's what's saved in database.
The online demo has the same code but demo doesn't save at all to test.
See attached screen shots.

Hi Telerik,
Just a heads-up - some of the demo pages are generating errors:
Server Error in '/aspnet-ajax' Application.
Runtime Error
Description: An exception occurred while processing your request. Additionally, another exception occurred while executing the custom error page for the first exception. The request has been terminated.
I have found this on:
The issue can be replicated with AutoCompleteBox demo: https://demos.telerik.com/aspnet-ajax/autocompletebox/examples/default/defaultcs.aspx
Set the SingleLineEntries property to "Enabled", and add a new Entry to the AutoCompleteBox. At this point, the page will scroll up and as a result hiding the AutoCompleteBox.
I just installed the latest release (Telerik_UI_for_ASP.NET_AJAX_2023_1_314) and the program gives me an error.
This is the error :
Test Environment:
OS: Windows_11URL: https://demos.telerik.com/aspnet-ajax/calendar/overview/defaultcs.aspx
Tool: Accessibility Insight for web.
Repro Steps:
1. Open URL: https://demos.telerik.com/aspnet-ajax/calendar/overview/defaultcs.aspx page in Edge Browser.
2. Navigate to calendar under overview Section by using tab key.
3. Run Accessibility Insight tool.
4. Verify the bug.
Actual Behavior:
Ensures the contrast foreground and background colors doesn't meet WCAG 2AA contrast ratio thresholds.
Expected Behavior:
Ensures the contrast between foreground and background colors meets WCAG 2 AA contrast ratio thresholds.
Environment (OS, Application, Versions)
Screen Reader: NVDA 2022.1
Repro-Steps:
- Open Telerik Web UI Calendar Overview Demo | Telerik UI for ASP.NET AJAX
- Navigate to calendar.
- Navigate to Next/Previous month ('<,<<,>,>>) button and activate it.
- Verify the issue.
Screen reader should announce the information about the month after activating "Next/previous" month controls.
Looks like it is a typo in the Telerik code. When I use skin web20 on the page and RadNotification I get exception :
An error occurred processing a web or script resource request. The requested resource 'pTelerik.Web.UI.Skins|Telerik.Web.UI.Skins.Web20Lite.Notification.Web20.css' does not exist or there was a problem loading it.
Note, there is "p" before Telerik namespace.
"Error while executing filter StripDomEventAttributesFilter - RangeError: Maximum call stack size exceeded"
Once the error occurs, the only way to fix it is to refresh the page.
The R2 2021 update causes all controls in Classic RenderMode to change their layout and size due to different font-size, font-family and line-height.
Fixing this change is planned for the upcoming Service Pack.
In the meantime, you can use the styles in the attachment. Due to the fact that the selectors are the same as the ones in the built-in skin, you need to load them either in the beginning of the <body> or using RadStylesheetManager. If you are using the StylesheetManager, ensure you set a big OrderIndex for the entry:
<telerik:RadStyleSheetManager runat="server" >
<StyleSheets>
<telerik:StyleSheetReference Path="fixes.css" OrderIndex="99999" />
</StyleSheets>
</telerik:RadStyleSheetManager>Loading the styles in the <head> tag's markup would not work as the Telerik stylesheets are added programmatically at the end of the <head> tag, meaning it will override the preceding files that have the same selector.
The attachment contains a file for each skin and inside it, it has all styles grouped by control. That means you can load only the file for the skin you are using and optionally remove the styles for controls that you are not using. Keep in mind that some more complex controls(e.g. Grid, Editor, DropDownTree, etc.) contain other Telerik controls as child controls, so you would need to keep the styles for the child controls also.
Please excuse us for the inconvenience caused and thank you for your understanding.

Description:
I have found a Cross-Site Scripting issue in the rich text editor, RadEditor. This is not in a body where user provides certain strings, rather it's in the text properties which gets sent along with the user input, such as font-style. The developers were able to follow the filtering mechanisms given in at https://docs.telerik.com/devtools/aspnet-ajax/controls/editor/managing-content/prevent-cross-site-scripting-(xss), but it provides protection for the inputs given in <textarea>, and for the properties values. Hence XSS is still possible
Steps for Reproduction:
1. Open up the text editor {{Screenshot 2020-09-23 at 12.08.51 PM.png}}
2. Input a string and change its font style.
3. Click on submit and intercept the request. {{Screenshot 2020-09-23 at 12.14.45 PM.png}}
4. Now we need to modify the request body for parameter of texteditor's ID. You may notice that the font-style is set and sent by using a <span>.
RadEditor1=%253cspan%20style%253d%2522font-family%253a%20%2527MS%20Sans%20Serif%2527%253b%2522%253etextexttext%253c%2Fspan%253e
Change parameter 'RadEditor1's value with the following:
RadEditor1=%253cspan%20onmouseover%253d%2522document.body.innerHTML%253d%2527ioioioioioioioioo%2527%252bdocument.cookie%2522%20style%253d%2522font-family%253a%20%2527MS%20Sans%20Serif%2527%253b%2522%253etextexttext%253c%2Fspan%253e
5. Submit and notice the 200 OK response. Now go to the text editor and notice that the string texttexttext can be seen. {{Screenshot 2020-09-23 at 12.24.18 PM.png}}
6. Put a mouse cursor on the string and notice that it gets changed to ioioioioioioioioo<domainCookies>.

Hello,
I have noticed the changes in your website, demos and documentation, but not all seems to work well on IE 11.
In the new interface of
the left menu dissapear after more clicks (IE11)
However, in ASP.net AJAX demos, the new interface is not looking good on IE 11
For example, https://demos.telerik.com/aspnet-ajax/orgchart/examples/expandcollapse/defaultcs.aspx
The old interface was looking great, I had no problems at all, any control
I hope I will not have the same problems in my ASP.net application...
Editor is not maintaining the Format of text, specifically the bullet numbers, when copied from MS word.
You can use the attached content to reproduce the problem in the Overview demo of the control.
An error will occur when the Index equals the number of items in the collection
private static ClientOperation<T> Remove(ControlItemCollection items, int index)
{
if (index < 0 || index > items.Count) // should be >= instead
return null;
var item = items[index];
items.RemoveAt(index);
var operation = new ClientOperation<T> {Item = (T) item, Type = ClientOperationType.Remove};
return operation;
}
