The old https://nuget.telerik.com/nuget server is obsolete since November 2024. If you use it the following error occurs: 

Failed to retrieve information about 'Telerik.UI.for.Maui' from remote source 'https://nuget.telerik.com/nuget/FindPackagesById()?id='Telerik.UI.for.Maui'&semVerLevel=2.0.0'.

As a solution use the v3 server. To redirect your feed to the NuGet v3 protocol, all you have to do is to change your NuGet package source URL to https://nuget.telerik.com/v3/index.json The new v3 API is faster, lighter, and reduces the number of requests from NuGet clients. The new v3 protocol offers faster package searches and restores, improved security, and more reliable infrastructure.  For more details about the Telerik NuGet Server review the Telerik MAUI NuGet Server documentation.

I am using Localization using ResourceManager. I have created various TelerikResource resx files with various languages.

I have added various Localization keys from various Telerik controls in there and translated them.

In App.xaml.cs constructor I call: 

            TelerikLocalizationManager.Manager.ResourceManager = TelerikResource.ResourceManager;
            InitializeComponent();

This works fine and my Telerik controls are translated.

Now the user can change the culture from the application. I call this method:

    public void SetCulture(CultureInfo culture)
    {
        MobileGeneratedLocalization.Culture = culture;
        TelerikResource.Culture = culture;
        TelerikLocalizationManager.Manager.ResourceManager = TelerikResource.ResourceManager;
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(null));
    }

I configured the application to use customized Theme Colors (Swatches) following the link:

https://docs.telerik.com/devtools/maui/styling-and-themes/customize-the-theme#customizing-the-theme-colors-swatches

Next as requirement I should change the Theme Color (Swatch) at run-time based on the device, using C# code, the only link I found was:

https://docs.telerik.com/devtools/maui/knowledge-base/change-telerik-theme-runtime

But here the Telerik Theme is changed at run-time using only pre-defined Telerik Themes. So my question is: how can I change Default Theme Colors (Swatches) at run-time using C# code?

Thanks

Hello,

I have installed the trial version of the Maui package [2]. After that I created an empty project: [1] 

1. In VS Code, open the Command Palette menu by pressing Ctrl+Shift+P on Windows or Linux, or Cmd+Shift+P on Mac.
2. Select Telerik UI for .NET MAUI Template Wizard: Launch and press Enter

When I try to run/build it, I get this error: 

NU1101: Unable to find package Telerik.UI.for.Maui.Trial. No packages exist with this id in source(s): /usr/local/share/dotnet/library-packs, NuGet

Which makes sense because there is no Telerik.UI.for.Maui.Trial at this location. 

What am I doing wrong?

Thanks!

I know this isn't entirely related to Telerik.

I read on GitHub, in the Windows App SDK repository, that there is an issue with dragging UI elements when running an app elevated as an Administrator.

In the past, I built my own GridSplitter using the drag-and-drop gesture in an older version of MAUI, and it worked perfectly. However, now with MAUI 9, if I run the app as an Administrator, dragging crashes the app with a "Catastrophic failure. Drag start failed. If this is an elevated process, drag/drop is not supported there." due to UAC limitations.

If I run it normally, everything works fine.

I was wondering if your new RadGridSplitter control and other similar controls in the Windows build also crash when using drag in Admin mode?
I project to replace mine by yours 😉

I know that some developers implement their own custom drag-and-drop manager. Have you done something similar in your Telerik MAUI package? If so, can it be used as a replacement for the built-in Windows App SDK drag-and-drop API?

Hy,

I created a blank MAUI APP project in NET 9.0 and added the following dependencies:

Also adding the dependency to the Telerik package (the last version):

It reports the following warning to me:

Found conflicts between different versions of "System.Security.Cryptography.Pkcs" that could not be resolved.

If I remove the reference to the Telerik package, the warning disappears.

Any help?

Thanks in advance

We recently discovered that our .NET MAUI APP (8.0.92) throws a Java.Lang.RuntimeException with Font asset not found /data/user/0/app.xyz/cache/telerikfont.ttf.

Here's the full exception detail:

Java.Lang.RuntimeException:
   at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw (System.Private.CoreLib, Version=8.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e)
   at Java.Interop.JniEnvironment+StaticMethods.CallStaticObjectMethod (Java.Interop, Version=7.0.0.0, Culture=neutral, PublicKeyToken=84e04ff9cfb79065)
   at Java.Interop.JniPeerMembers+JniStaticMethods.InvokeObjectMethod (Java.Interop, Version=7.0.0.0, Culture=neutral, PublicKeyToken=84e04ff9cfb79065)
   at Android.Graphics.Typeface.CreateFromAsset (Mono.Android, Version=0.0.0.0, Culture=neutral, PublicKeyToken=84e04ff9cfb79065)
   at Microsoft.Maui.FontManager.LoadTypefaceFromAsset (Microsoft.Maui, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null)

We do have a "Font" folder in our Application, but in our understanding this shouldn't be a problem anymore.

We register those fonts, which are in the Fonts folder:

.ConfigureFonts(fonts =>
{
	fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
	fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
	fonts.AddFont("FontAwesomePro-Light-300.otf", "FontAwesomeLight");
	fonts.AddFont("FontAwesomePro-Regular-400.otf", "FontAwesomeRegular");
	fonts.AddFont("FontAwesomePro-Solid-900.otf", "FontAwesomeSolid");
});

In addition to that, we have a custom CustomFontsProvider for the fonts we use in the RadPdfProcessing lib for .NET MAUI. Those fonts are however in the RAW.

public class CustomFontsProvider : Telerik.Windows.Documents.Extensibility.FontsProviderBase
{
    public override byte[] GetFontData(Telerik.Windows.Documents.Core.Fonts.FontProperties fontProperties)
    {
        string fontFileName = fontProperties.FontFamilyName + ".ttf";

        if (fontProperties.FontFamilyName == "Verdana")
        {
            if (fontProperties.FontStyle == FontStyles.Normal && fontProperties.FontWeight == FontWeights.Normal)
            {
                fontFileName = $"Verdana.ttf";
            }
            elseif (fontProperties.FontWeight == FontWeights.Bold)
            {
                fontFileName = $"Verdana-Bold.ttf";
            }
        }

        var fileStream = FileSystem.Current.OpenAppPackageFileAsync(fontFileName).GetAwaiter().GetResult();

        var memoryStream = new MemoryStream();
        fileStream.CopyTo(memoryStream);

        return memoryStream.ToArray();
    }
}
 
How can we resolve this issue? Any support is appreciated.
