Fixed in Telerik.Licensing NuGet package version 1.4.10. Install this (or later) version of the package to avoid the issue.

Build errors may occur in situation where you have two projects one depending on the other, and the main project installs the Telerik.Licensing nuget package. The package triggers a set of MSBuild taks and at some point an IncrementalClean is invoked, which deletes some of the files and errors occur during the build.

The error message that can occur:

 

CSC : error CS0006: Metadata file 'dll/file/path/here.dll' could not be found [project directory path here]

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!

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.

After upgrading to .net 9 I get the following error when starting the published program (running it in RIDER in debug-mode doesn't create the issue).


System.TypeInitializationException: The type initializer for 'Telerik.Windows.Input.Touch.TouchManager' threw an exception.
 ---> System.IO.FileNotFoundException: Could not load file or assembly 'System.Windows.Forms, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. Das System kann die angegebene Datei nicht finden.

 

the mentioned assembly System.Windows.Forms is not used by me at all.

Suddenly with WPF release 2024 Q4 some of pdf-s are not presented correctly. Attached file was produced with Telerik Report Designer and exported as pdf. With previous WPF version was OK.

You can check in your demo application. It is shown in previous release but not with latest.

Please make solution ASAP.

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

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.

Currently, the Telerik UI for WPF product does not have an editor that works mainly with the DateTimeOffset value type. We could introduce such an editor.

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!

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.

Using RadTabbedWindow I noticed difficulty dragging maximized windows between monitors. It seems to happen in multi-monitor environments and only when dragging Left of the PrimaryScreen.

In the video I've included , the blue window is a standard window and can be maximized in one drag across any display.

The white window is RadTabbedWindow and the drag will default to the PrimaryScreen when dragged to the left-most display.

Any help would be appreciated. Thanks
