Hello,

Sometimes the context menu isn't positioned correctly when it pops up for the first time, or after you scroll the page or do a browser zoom. I've attached an example reported by our tester. I've checked your technical support and have found this:

https://feedback.telerik.com/aspnet-ajax/1374622-context-menus-mispositioned-after-page-scroll-when-contentareamode-div?_ga=2.47056743.1148387732.1712639084-795296971.1689564005&_gl=1*1fbejbs*_ga*Nzk1Mjk2OTcxLjE2ODk1NjQwMDU.*_ga_9JSNBCSF54*MTcxMjcwNTQxNS42NS4xLjE3MTI3MDY1NTUuNjAuMC4w*_gcl_au*MTk5NTg1MzE3OS4xNzEyMjAwMDcy

I've tried setting the render mode to Lightweight (originally set to Auto), but unfortunately no luck.

Is this something that is fixed in a later version of the editor, or do you have another fix/workaround?

Thank you in advance,

Gerald

In RadEditor when specifying WordIgnoreOptions="None", I would expect that "THe" would be flagged as a misspelling, but it is not. It appears the WordIgnoreOptions is being ignored.

Hello,

For ASPX.NET AJAX... JQuery 1.x branch is still being utilized / embedded (even though some of the bigger issues have been manually changed by your Progress Team) does not cut it with our client base. JQuery Branch 1.x is not acceptable and has been a Severe security item for ALL PEN testing solutions for some time.

What are the Progress plans to get jQuery up to SPEC (3.7.x... etc.). We have no interest in over-riding the version of jQuery as is noted in some of the forums. This creates other issues at the Telerik component level... we do not want to deal with component issues as that is why we procure 3rd party Components in the first place.

"Security is paramount over functionality in most web applications today."

This is major, as we would have to move on to other technologies if your roadmap does not meet our needs. Q1 2025 at min.

I am certain many other users are in the same boat.

Kind Regards

I'd like to have a built-in feature for RadTreeList Export to Excel grouping. My data has a hierarchy, and I want to be able to export it to excel with a collapsible/expandable row functionality based on the hierarchy/level.

When frozen column is used in the Grid, when user moves the cursor onto an out-of-the-screen element in the table header, the screen will not scroll automatically to make the element shown. When frozen column is not used, there's no such issue. This should be a bug of the RadGrid control.

Release 2025 Q1 (Feb)
Update the Render methods in XlsxRenderer.cs and DocxRenderer.cs to replace obsolete Export method overloads from IWorkbookFormatProvider and DocxFormatProvider. These methods now use the updated overloads that include a TimeSpan? timeout parameter. Add a new timeout setting SecurityHelper.ExportTimeout to ensure configurable timeout handling across the application. The update resolves compiler warnings (CS0618) caused by the usage of deprecated method overloads and aligns with modern practices for enhanced application performance and reliability.

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>

Based on Ticket ID 1683806  it was suggested to add this here.  It should be fairly straight forward and would resolve issues that I have.

My Suggestion:

Why can you not just add the clientEvents to the RadEditor1.FileExplorerSettings

Something like RadEditor1.FileExplorerSettings.ClientEvents.OnClientFileOpen="somefunction"

 

Your response.

Thank you for your suggestion to add client events directly to RadEditor1.FileExplorerSettings. It's a thoughtful idea that could indeed enhance client-side flexibility and streamline interactions.

At present, this feature is not available. However, we encourage you to submit it as a feature request through our public feedback portal, where our product team actively reviews community input for potential inclusion in future updates.

 

Also, please see my ticket for a bug in the ImageManager using th URL to return the item instead of the OriginalPath.  This makes my custom content provider not feasible.

 

 

Thanks!

Hi,

    many customers are asking us a more MS Word-like editor supporting true document layout features such as:

  • page margins and rulers
  • Headers and footers
  • section breaks or document structure more similar to MS Word
  • Microsoft Word-inspired UI

Many thanks,

Max

Yes, ASP.NET Webforms is outdated, but it's still around, and I think many developers are looking at moving to a newer and more modern technology. But in some cases - including mine - it's not really possible to refactor an application that has grown for 20 years overnight. The only thing I can do is put a lot of energy into changing the CSS of the controls. Which is not always easy.

I really appreciate the functionality of the Telerik controls and think it's a shame that they don't get a visual and functional update.

In this specific case, it is about the Datepicker Control, which has a different behavior than the more modern version under .NET Core. For example, the month or year selection opens in a new DIV popup. In the more modern control, this is solved in a more elegant and modern way.

I think that this list of controls that need a “front-end pimp” can certainly be extended.

Thank you!

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.

Summary 

After editing an Excel `.xlsx` file using Telerik RadSpreadsheet and saving it via the default Save option, the saved file becomes corrupted. It no longer opens in RadSpreadsheet (throws an error) and shows a repair warning in Microsoft Excel. 

Reproduction Steps 

1. Upload an Excel `.xlsx` file to the `ABC` folder on the server. 

2. Load the file in RadSpreadsheet via a basic viewer page. 

3. Make any small edit (e.g., change a cell’s value). 

4. Click the built-in Save option in the RadSpreadsheet toolbar. 

5. Attempt to: 

   - Reopen the saved file in RadSpreadsheet → Error: Object reference not set to an instance of an object. 

   - Open in Excel → Warning: “We found a problem with some content in ‘filename’. Do you want us to try to recover as much as we can?” 

Files Attached 

- `Original.xlsx` — Before editing, opens fine in both RadSpreadsheet and Excel. 

- `Modified.xlsx` — After saving via RadSpreadsheet, causes errors. 

- Screenshot of: 

   - RadSpreadsheet error : 

Picture 

   - Excel repair prompt 

Picture 

Code Snippet : 

<telerik:RadSpreadsheet ID="sample" runat="server" Visible="false" style="font-size: 10px;" /> 

protected void Page_Load(object sender, EventArgs e) 

{ 

    string fileName = (string)Session["SelectedFileName"]; 

    SheetLoad(fileName); 

} 

  

private void SheetLoad(string fileName) 

{ 

    try 

    { 

        string filePath = Server.MapPath("~/ABC/" + fileName); 

        if (!File.Exists(filePath)) 

        { 

            string errorMsg = "File not found: " + filePath; 

            ClientScript.RegisterStartupScript(this.GetType(), "alert", "alert('File not found!');", true); 

            return; 

        } 

  

        // Load spreadsheet using Telerik document provider 

        sample.Provider = new SpreadsheetDocumentProvider(filePath); 

        sample.Visible = true; 

    } 

    catch (Exception ex) 

    { 

        string errorMsg = "Error opening file: " + ex.Message + " | File: " + fileName; 

        ClientScript.RegisterStartupScript(this.GetType(), "alert", "alert('Error loading file!');", true); 

    } 

} 

  

**Observation:** 

  

* This only happens for **some files**, especially ones that likely contain advanced Excel features. 

* Other simpler files save and reload without any issue. 

  

**Assumption:** 

It seems the default save behavior of RadSpreadsheet is **not preserving some Excel structures**, leading to file corruption on save.

We were looking to use Telerik’s RadEditor control to provide MS Word like editing provision but lacks some features of MS Word especially Header & Footer options which will be repeated in every page, as the RadEditor control does not support paging. Are we doing it correctly? Is there an option where paging is supported and header and footer will come across pages? Are there any other products that support MS Word editor functionality?

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
