Telerik NuGet Server v2 is Obsolete - Use v3 Instead

The old https://nuget.telerik.com/nuget server is obsolete since November 2024.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.

.NET MAUI app throws Java.Lang.RuntimeException with Font asset not found /data/user/0/app.xyz/cache/telerikfont.ttf

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.

Problem with using On Screen Keyboard in TabView on Android

I am using TabView with few Input lines (used for settings) on each tab. I use RadNumericalInput (have also tried RadEntry) as the Input Control.

When I focus an entry on the first tab, the On Screen Keyboard shows up and the screen moves up so that the Input Control is visible while I type in the value.

When I do the same on the second, or the third tab, the screen does not move, and the Input Control is hidden behind the keyboard.

Is this a bug, or is there a way to correct this.

Hal Einarsson.

RadListPicker Templates

Hi,

Are you able to provide the default control templates for the RadListPicker so that I can tweak them?

On Android the underline border is too far below the text and does not give a consistent look and feel compared to native controls.

Regards

RadScheduler appointment DoubleTap/LongPress Bug/Request

What im basically looking for is a solution for another gesture in addition to regular tap. (on an appointment).

Its split into 2 different options:
1. (Bug)

Using existing AppointmentDoubleTap event

I tried this but appearantly when using both events (regular and double tap) - the regular tap will immedietly be executed and so the doubleTap is never accessible.

2. (Request - preferably)

To add an option for a long press event on an appointment...
This is what i had in Xamarin and this is what i would ideally want here as well.

PS

Before suggesting - I did try to use CommunityToolkit behaviors for longPress but when its added to my appointment DataTemplate in the Xaml - the appointments do not appear, probably some conflict with Teleriks...
