Currently PropertyDefinitions have only one Property for DataBinding, which is very strange solution.

All these instances are DependencyObject, but at the same time they are not in the visual tree and we could not bind to a visibility or to readonly or to any other property without some starnge sorkarounds (why this was designed in this way?).

This makes these objects almost useless. becuae we cannot fully use them in an MVVM way (bindings, multiibindings, etc.)

Possible solutions:

  1. provide bindings for all properties to make them be bindable withput any workarounds
  2. Change PropertyDefinitions to something that will live inside visual tree.

Cobination of GetBestView() and SetView() with pixelPadding parameter set might result in such zoom value that Map does not show all of the items intended to focus in the viewport. Padding and should always visualize all items given in the list.

Currently the Windows 11 theme for Telerik WPF features the ability to switch backdrop material to Acrylic, Mica and None, but what it's missing the Mica ALT material.

Because of the substantial difference from the normal Mica material, and the ability it gives to create more modern looking applications we think that the addition of this backdrop material would greatly benefit an already very good looking theme!

Release Telerik UI for WPF 2024.4.1111 (2024 Q4)

When trying to install one of the following nuget packages an error occurs:

  • Telerik.Windows.Controls.EntityFramework60.for.Wpf.Xaml
  • Telerik.UI.for.Wpf.AllControls.Xaml (which contains the EF6 package from the previous bullet)

The same issue manifests with the NoXaml version of the same packages.

The error message is:

To work this around, To work this around, you can reference the Telerik.Windows.Controls.EntityFramework60.dll directly and manually install the EntityFramework package (version 6.4.4), instead of using the nuget package.

A XamlParseException is raised when the theme's resource dictionaries are not merged in App.xaml. The missing resource is the RepeatButtonStyle resource.

To work this around, merge the resource dictionaries for the theme in the Resources collection of the App.xaml file.

Hi,

it would be convenient to add an extra small font size to te existing enumerations. For instance in Windows 11 theme, could it be possible to add a XS size:

Windows11Palette.Palette.FontSizeXS = 10;
Windows11Palette.Palette.FontSizeS = 12; 
Windows11Palette.Palette.FontSize = 14; 
Windows11Palette.Palette.FontSizeM = 18; 
Windows11Palette.Palette.FontSizeL = 20; 
Windows11Palette.Palette.FontSizeXL = 28; 

Having a range in the bigger font sizes is very useful. It owuld be equally helpful to have a range on the smaller font.

Thank you for considering it :)

Hello,

HtmlDataProvider will throw an exception on export or when used by a RadRichTextBox, when using a html containing the length value "NaN", which doesn't seem to be a standard approved value, but nevetheless it is a special case because other invaild values are simply ignored while this one triggers two exceptions - one of which is hard to catch and crashes the whole application.

Hello together,

I am experiencing a bug with the following use case:

  1. Import an existing PDF file
  2. Modify the PDF file
  3. Export the PDF file

When upgrading Telerik.Documents.Fixed from version 2024.3.806 to version 2024.4.1106 the exported PDF file is missing different parts of the originally imported PDF file or even results in a complete "messy" file. Input and output files are view with Adobe Acrobat, Google Chrome, Edge...all showing the same result.

Even omitting step 2 (i.e. I only import and directly export the PDF file) results in the same bug after.

I do not use any special import or export setting to reproduce the error. But even with applying different import/export settings I could not change the buggy outcome.

 

var bytes = File.ReadAllBytes(@"C:\temp\in.pdf");
var formatProvider = new PdfFormatProvider();
var document = formatProvider.Import(bytes, TimeSpan.FromSeconds(20));
var outBytes = formatProvider.Export(document, TimeSpan.FromSeconds(20));
File.WriteAllBytes(@"C:\temp\out.pdf", outBytes);

See the attached file for example, import it and export it (via code snippet above).

With version 2024.3.806 everything works fine - and as I am not seeing any relevant breaking changes or other release information regarding this issue, I am a little bit lost with what I could do to solve the issue..

Thanks for your support!

A compilation error occurs in a project that doesn't use any Telerik code, but it references a class library which installs the Telerik.Licensing NuGet package. 

The error message from the class library project is the following:

C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Microsoft.WinFx.targets(268,9): error MC1000: Unknown build error, 'Cannot resolve dependency to assembly 'Telerik.Licensing.Runtime, Version=1.4.6.0, Culture=neutral, PublicKeyToken=keyhere' because it has not been preloaded. When using the ReflectionOnly APIs, dependent assemblies must be pre-loaded or loaded on demand through the ReflectionOnlyAssemblyResolve event.'

To workaround this, you can add assembly references to the Telerik dlls in the main project (including Telerik.Licensing.Runtime), instead of using NuGet packages.

Alternatively, you can install the Telerik.Licensing NuGet package also in the class library.

<ItemGroup>
	<PackageReference Include="Telerik.Licensing" Version="1.4.*" />
</ItemGroup>

Note that with this approach you will see a message in the output that no license is installed, even if you have one. However, for now (versions from 1.4.6 to 1.4.12, which is the latest at the moment of writting this post), the error won't apply any compile or runtime restrictions on the UI or the functionality.

Dear Support-Team,

We have an issue with a translation on the spreadsheet print preview.

It shows there in the dropdown for the scaling several Netherland translations on a German system.

The text should be like:

1. Blatt für eine Seite anpassen
Den Ausdruck verkleinern, damit er auf eine Seite passt.

2. Alle Spalten passen auf eine Seite
Den Ausdruck verkleinern, so dass er eine Seite breit ist.

3. Alle Zeilen in eine Seite einpassen
Den Ausdruck verkleiner, so dass alle Zeilen auf eine Seite passen

Could there be a fix for this issue?

Kind regards,

Anna

Windows 11

VS 2022

UI for WPF (2024 Q4)

.NET 8

Binaries.NoXaml\WPF80\Telerik.Windows.Controls.RichTextBox.dll (2024.4.1213.80)

I can create a docx file with Word that results in a null reference exception at

NameValueType
StackTrace" at Telerik.Windows.Documents.Layout.ParagraphLayoutBox.ArrangeOverride(SizeF finalSize) in Telerik.Windows.Documents.Layout\\ParagraphLayoutBox.cs:line 1174"string

Since this exception is in a threadpool that is doing layout, the exception cannot be caught and is not recoverable.

It is easy to reproduce (see attached file). First create a Word doc with a large image that is anchored. Then add a bookmark. Removing either the bookmark or the "square" text wrapping removes the exception.

The code to load the document and display it is very simple:


   private string? LoadDocx(
      string path)
   {
      string? msg = null;
      try
      {
         using var instream = File.OpenRead(path);

         var openXmlRadDocProvider =
            new Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.DocxFormatProvider();

         var raddoc = openXmlRadDocProvider.Import(instream);
         RadRtb.Document = raddoc;
      }
      catch (Exception ex)
      {
         msg = ex.Message;
      }

      return msg;
   }

"RadRtb" is a "RadRichTextBox". This method returns fine. The exception happens later in a non-UI threadpool thread.

 

While I don't expect the component to correctly render EVERY Word document, I do expect it to not exception on a valid document. There must be a better way to handle this.
