I'm using a RadTab and one of the RadPageViews starts with an RadAsyncUpload-Control. When I use arrow keys to select this tab and try to use the Tab-Key to focus the next element (the RadAsyncUpload in this case) nothing happens. If any other control (like a textbox) is placed above my upload control there is no problem focusing it.

You can see this in the attached Demoproject when using arrow keys to select to RpvUpload.

Dear staff I know this post

https://www.telerik.com/support/code-library/detecting-changes-to-the-radeditor

But in any case the component RadEditor have the method 'OnTextChanged' in the client side.

Probably, id it doesn't works, is better to remove it.

Thanks

The problem is that when you click the buttons, the RadDateRangePicker is filled with the start of 2025-06-01 and the end of 2025-06-30. Then, when you click the button again, a change should occur in the RadDateRangePicker: start of 2025-07-01 and end of 2025-07-31.


1 step => correct

2 step => incorrect


Result
The first time you click the button, it returns the start date to 06/01/2025 and the end date to 06/30/2025 (this is correct). Clicking it again returns the start date to 06/30/2025 and the end date to 07/31/2025 (this is incorrect).

Work around
 - Local page
js code fixed 

const datepicker = $find('<%= radDateRangePicker2.ClientID %>');

datepicker.set_rangeSelectionStartDate(null);
datepicker.set_rangeSelectionEndDate(null);

- Global fixed All controls
C# in extension control 

public bool EnableDateResetting
{
    get => ViewState["EnableDateResetting"] as bool? ?? false;
    set => ViewState["EnableDateResetting"] = value;
}

public eDateRangePicker() : base()
{
	Load += EDateRangePicker_Load;
}

private void EDateRangePicker_Load(object sender, EventArgs e)
{
    if (EnableDateResetting)
    {
        RegisterDateResettingScript();
    }
}

private void RegisterDateResettingScript()
{
	string script = $@"
		Sys.Application.add_load(function() {{
			const picker = $find('{ClientID}');

			if (picker) {{
				const origStart = picker.set_rangeSelectionStartDate;
				const origEnd = picker.set_rangeSelectionEndDate;

				picker.set_rangeSelectionStartDate = function(date) {{
					if (date !== null && !this._isResetting) {{
						const currentStart = this.get_rangeSelectionStartDate();
						const currentEnd = this.get_rangeSelectionEndDate();
                
						if (currentStart || currentEnd) {{
							this._isResetting = true;

							origStart.call(this, null);
							origEnd.call(this, null);

							this._isResetting = false;
						}}
					}}

					return origStart.call(this, date);
				}};

				picker.set_rangeSelectionEndDate = function(date) {{

					return origEnd.call(this, date);
				}};
			}}
		}});
	";

    ScriptManager.RegisterStartupScript(this, GetType(), $"DateResetting_{ClientID}", script, true);
}

Simple reproducible is attached to illustrate the problem.

A workaround may be replacing RadButtons that invokes such postbacks with regular buttons and using a form decorator

Alternatively, you can simply disable the handler URL encryption

You can also put the following in the global.asax file to prevent the version from rendering on the page markup
        protected void Application_BeginRequest(object sender, EventArgs e)
        {
			System.Web.HttpContext.Current.Items["_!TelerikVersionStampRendered"] = true;
        }
or you can add the same line in a global Page_Load handler (e.g., in a base page class or in the master page your project uses)

ChatGPT recommended "Turn off Telerik’s “old” ARIA settings (they are overly strict and often invalid):"

i removed it and it worked. WTH?

What i supposed to do now? I added these settings in all our products

When using client-side code to filter my Grid, the "BETWEEN" filter does not work well when filtering DateTime values where the time is after 12:00 AM.

i.e., filtering the dates between 9/11/2025 and 9/12/2025 does not include 9/12/2025 at 12:01 AM or any date where the time is after 12:00 AM.

Additionally, when passing datetime values to the filter function, the time component is dropped afterward.

var filter = "9/11/2025,12:00:00,AM 9/12/2025,11:59:59,PM"
tableView.filter(columnName, filter, "Between");

I recently upgraded the Telerik version from 2025.1.416 to 2025.3.825, and started getting this NullReferenceException during debugging.

I noticed I get the error when debugging RadGrid with the Skin property.

The Box Plot Chart throws the following errors when used:

RadHtmlChart.js:1 Uncaught ReferenceError: series is not defined
Uncaught (in promise) ReferenceError: series is not defined

While changing the value from RadCombox, meaning firing the SelectedIndexChanged, I am getting the below error.

When trying on localhost SelectedIndexChanged of RadCombobox is getting fired and rgrid_NeedDataSource of RadGrid is not fired but when deployed on IIS, the scenario is opposite, SelectedIndexChanged is not fired but rgrid_NeedDataSource is getting fired.

Please help.

Also another thing, I wanted to understand how to use licenses.licx file in our project for telerik dll version 2013.1.314.45?

Dear Telerik Support.  I found another bug related to this one below.

https://feedback.telerik.com/aspnet-ajax/1688270-uncaught-typeerror-cannot-read-properties-of-null-reading-classname?_gl=1*iuxa0l*_gcl_au*NjcwNTkzNi4xNzQ3Njc4MzQz*_ga*OTAxNzk1OTc4LjE3Mzk4MjI5NzY.*_ga_9JSNBCSF54*czE3NDgwOTkxODEkbzIxJGcxJHQxNzQ4MDk5NTIzJGo1NCRsMCRoMCRkRlJROUp0Q0RDUUZTUlZUeFlLLU9ja3RBc2UwczF3ZU55Zw..

This line of code also causes the same issue.

$find("txtYear").clear();

See attached Console debug output.

It is my opinion that a hot fix needs to be done asap!  The work around that Derek posted on May 23rd falls short of the bigger issue.  This is a serious matter and needs to be addressed immediately.

Hello Progress team,

we're using the HtmlChart and RadialGauge components of your Telerik for AJAX suite and are encountering some inconsistencies between the two.

To be able to use the exportable SVGs of those components server-side, we've extended your classes and added two asp:HiddenFields each, so we can post the SVG and the dimensions back to the server for further processing. (Setting the values is handled in a button OnClientClick JavaScript function, that's irrelevant to this thread.)

As of 2019, when we first introduced the respective feature in our software, the code looked like this:

• Similar for both components
• In both cases the additional HiddenFields get added to the Controls-List "OnInit" before the base.OnInit-event.
• In both cases we had to override the "Render"-function to also render the HiddenField-Controls to the HTML.

public class ExportableRadHtmlChart : RadHtmlChart, INamingContainer
{
    private HiddenField _svgData = new HiddenField();
    private HiddenField _svgDimensions = new HiddenField();
    public ExportableRadHtmlChart()
    {
        _svgData.ID = "SVGData";
        _svgDimensions.ID = "SVGDimensions";
    }

    protected override void OnInit(EventArgs e)
    {
        Controls.Add(_svgData);
        Controls.Add(_svgDimensions);
        
        base.OnInit(e);
    }
    
    protected override void Render(HtmlTextWriter writer)
    {
        writer.RenderBeginTag(HtmlTextWriterTag.Div);

        base.Render(writer);

        _svgData.RenderControl(writer);
        _svgDimensions.RenderControl(writer);

        writer.RenderEndTag();
    }
}

and

public class ExportableRadRadialGauge : RadRadialGauge, INamingContainer
{
    private HiddenField _svgData = new HiddenField();
    private HiddenField _svgDimensions = new HiddenField();
    public ExportableRadRadialGauge()
    {
        _svgData.ID = "SVGData";
        _svgDimensions.ID = "SVGDimensions";
    }

    protected override void OnInit(EventArgs e)
    {
        Controls.Add(_svgData);
        Controls.Add(_svgDimensions);
        
        base.OnInit(e);
    }

    protected override void Render(HtmlTextWriter writer)
    {
        writer.RenderBeginTag(HtmlTextWriterTag.Div);

        base.Render(writer);

        _svgData.RenderControl(writer);
        _svgDimensions.RenderControl(writer);

        writer.RenderEndTag();
    }
}

With this code, we've been running the Telerik product version 2023.1.323.45.

Now, we've updated to Telerik product version 2025.1.416.462 and are experiencing the following inconsistencies:

1. Using the same code as before, the HiddenFields of class "ExportableRadHtmlChart" render twice:
   
   
   Whereas previously, they've only rendered once:
   

   

   Removing the custom "Render"-function of the class "ExportableRadHtmlChart" resolves this issue. (Having duplicates of those HiddenFields actually causes issues on repeated PostBacks, as two HiddenFields at a time have the same ClientID and thus their values get packed as a comma separated list before transmission to the server, which in turn yields issues when parsing the SVG, which in reality are multiple comma separated SVGs.
   
   The SVG values are truncated in this view, but the dimensions paint a pretty clear picture, as to what's happening here after 4 PostBacks.) Despite requiring to make this adjustment to our software, we're glad, we can discard that custom "Render"-function.
   
2. The "ExportableRadRadialGauge", on the other hand, still only renders the HiddenFields with the custom "Render"-function included. Can we expect a similar fix to the RadialGauge, s.t. we don't require to render the HiddenFields ourselves?

As I'm unsure of the "Theme name", I've put "ControlDefault". But I don't think that should matter too much. If it does, I'll try to find the correct value.

Kind regards,
Matthias

Hello -

I just updated my components to 2025.1.218, and am receiving the following ADA Compliance issues on a page scan.  This is to conform to WCAG 2.1 AA.  The component is the Ajax telerik:RadComboBox:

Buttons must have discernible text

<button class="rcbActionButton" tabindex="-1" type="button">select</button>

Form elements must have labels

<input name="ctl00$MainContent$ComboBox$NewCombo" type="text" class="rcbInput radPreventDecorate rcbEmptyMessage" id="ctl00_MainContent_ComboBox_NewCombo_Input" value="Search..." autocomplete="off"></input>

Component in .ascx file:

Please advise.  Thanks!

When pasting bullet lists from Microsoft Word into the editor, extra leading spaces (&nbsp;) appear in the list items. This causes unexpected indentation and formatting issues.
