It is possible for a user to type a value into a RadNumericUpDown control that is greater than the maximum (or smaller than the minimum).

If the control loses focus the value reverts to the maximum value, but in my use case the user will be clicking the OK button on a Window, and this happens while the NumericUpDown still displays the out of range value that was typed. In other words the user doesn't realise that their value was silently rejected behind the scenes.

To solve this I had to raise a support request with you guys, which meant waiting until the next day for a resolution. This cost me time and it also added to your workload.

Whereas if the control had the option to limit the user input to the bounds of minimum and maximum it would have saved me about half a days work to raise a support request and write my own solution to the problem.

I see this has been raised a couple of times in the forums:

https://www.telerik.com/forums/prevent-user-from-typing-beyond-maximum-value

https://www.telerik.com/forums/radnumericupdown-lets-you-type-beyond-its-maximum-value

And the consensus seems to be that it is "By Design".

Please can you re-consider changing this as it is these small niggles that often cost us the most time when developing with 3rd party controls.

TIA

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.

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!

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:

Severity Code Description Project File Line Suppression State Details
Error Failed to add reference. The package 'Telerik.Windows.Controls.EntityFramework60.for.Wpf.Xaml' tried to add a framework reference to 'EntityFramework' which was not found in the GAC. This is possibly a bug in the package. Please contact the package owners for assistance.
Reference unavailable.

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.

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.

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.

Code to reproduce:  Console App / .Net Framework 4.8 / Package Telerik.Windows.Documents.FormatProviders.Html.for.Wpf 2022.3.912

using System;
using Telerik.Windows.Documents.FormatProviders.Html;
using Telerik.Windows.Documents.Model;

namespaceHtmlProviderCrash
{
    internalclassProgram
    {
        static void Main(string[] args)
        {
            var htmlContent = "<img src=\"https://static.cleverpush.com/notification/icon/92fYF7FtKbthsezwS.png?element=Le7adDwC\" " +
"alt=\"\" style=\"display: inline-table;max-width: 100%;width: 300px;\" width=\"300\" height=\"NaN\" class=\"cp-element-image light-img\">";

            HtmlFormatProvider htmlProvider = new HtmlFormatProvider();
            RadDocument document = htmlProvider.Import(htmlContent);

            try
            {
                var export = htmlProvider.Export(document);
            }
            catch (Exception ex)
            {
                var ka = ex.ToString();
            }
            while (Console.ReadKey().KeyChar != 'x') { }
        }
    }
}

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.

Currently SvgImage does not support the following inner animation:
