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

    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?

    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

    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:

    <telerik:RadComboBox ID="ComboBox" runat="server" RenderMode="Lightweight"
        EmptyMessage="Search..."
        AllowCustomText="true"
        MarkFirstMatch="true"

    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.

    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.

    Replace the obsolete Import method overload in RadEditor source code. These method now use the updated overload that include a TimeSpan? timeout parameter. Add a new timeout setting SecurityHelper.ImportTimeout to ensure configurable timeout handling across the application. The update aligns with modern practices for enhanced application performance and reliability.

    Hello

    I have an ASP.NET Ajax Telerik Solution (site) that has a web site project and a library project.  The solution was developed almost 8 years ago and so far I've been able to upgrade telerik controls  several times without any problem. Now, when I tried to upgrade the Telerik controls using the Upgrade Wizard Project only shows the class library as you can see in the attached picture.

    To replicate this beahavior:

    1. Create a new Telerik VB Webform Site
    2. Add a Class Library Net Framework project to the solution.
    3. Add a reference to Telerik.Web.UI to the Class Library project (optional).
    4. Save and close solution.
    5. Reopen it and run the Telerik Upgrade Wizard Project.

    It only shows the Class Library project ...

    This request was necessary because ticket 1665797 don't solved.

    There is a formatting issue in the editor when the "Tab" key is pressed, triggering the editor's "InsertTab" event on text that has been modified by another user. In this event, when set_enableTrackChangesOverride(true) is enabled, the editor inserts an "a" character and misformats the text in question (as shown in the video). When set_enableTrackChangesOverride(false) is set, this error does not occur.

    Note: In this scenario, we need track changes enabled so the user can accept or reject the changes made by the previous user, and set_enableTrackChangesOverride(true) so that the current user can reconcile the changes made by both User 1 and User 2 without tracking their own modifications.

    Before insert Tab:


    After insert Tab:

    Hello,

    I'm facing JavaScript issues after enabling "Telerik.ScriptManager.EnableHandlerEncryption" on Web.config,

    I've just followed Encrypt Telerik WebResource Querystring in order to hide the Telerik version.

    After this the RadMenu breaks when i do a PostBack action (by pressing a button), the console outputs the same error when hovering a RadMenuItem and the submenus has stop being displayed.

    The console error:

    Uncaught TypeError: Cannot read properties of null (reading 'apply')
      at Type.callBaseMethod (Telerik.Web.UI.WebRe...=:6:7353)
      at c.RadMenuItem._createChildControls (Telerik.Web.UI.WebRe...=:5300:49)

      at HTMLDivElement.<anonymous> (Telerik.Web.UI.WebRe...=:6:307)
      at HTMLDivElement.b (Telerik.Web.UI.WebRe...=:623:53)

    I've tested this error with version 2020.2.617.45 and 2022.3.913 but the same problem.

    Looking in the forum i've found this post with a related issue also a reply has a reference to a private feedback and this last one seems to be the same or almost the same problem, so i've tried to follow the workaround on "global.asax" file and "Page_Load" on the master page without luck.

    The steps i've follow:

    • Enabling "Telerik.ScriptManager.EnableHandlerEncryption".
    • Site seems working correctly.
    • I press a RadButton inside a RadAjaxPane.
    • Response from server is OK.
    • Then i hover the cursor on RadMenuItems on RadMenu.
    • Console starts to show the related error explaining above.
    • RadMenu stops to present the submenus completely.

    I'd like to have another way to workaround this in order to make RadMenu work properly again and keep Telerik version hidden.

    Pasting plain text content from notepad or other text editor into the RadEditor control (design view) results in container HTML tags adding to the content and inline styles that make the text unreadable.

    Content pasted:
