When adding Telerik controls on the page and run the app on android, the following error message occurs runtime:

Java.Lang.RuntimeException stack trace ---
java.lang.RuntimeException: Font asset not found /data/user/0/com.companyname.appname/cache/telerikfont.ttf
	at android.graphics.Typeface.createFromAsset(Typeface.java:1061)
............

This error message does not prevent the app from working as expected, but the log is full of this message. 

When using Telerik controls, I got the following warning:

 Not linking with the framework OpenGLES referenced by a module reference in SkiaSharp.Views.iOS.dll

when I add a SkiaSharp 3.116.1 version to the project, the warning disappear.

Please update the SkiaSharp package reference in the Telerik MAUI NuGet package

Hi Team,

I would like to be able to have client-side filtering/sorting/grouping capabilities for large backend datasets that cannot be entirely loaded on the client.

As it stands now, the DataGrid (and other data components) can only operate on the data that is has in the local DataView. This means that I need to build a custom filtering solution that prefilters/presorts the backend data before paging and loading it into the DataGrid.

To accomplish the "full view", we need a data layer that understands both the UI as well as the backend. The Telerik UI for WPF product has an excellent solution for this, known as the WPF EntityFrameworkCoreDataSource - Overview - Telerik UI for WPF and the WPF DataServiceDataSource - Overview - Telerik UI for WPF.

If such a feature can be added to Telerik UI for MAUI, it would be an excellent bonus for the component suite in data heavy applications.

Thank you,

Peter

ListView with a TemplateSelector crashes on iOS 16 device!

Hi,

Do you have on your roadmap to include a Shimmer View / Control as part of your .NET MAUI offerings to tidy up a screen loading indication.

From a UI/UX perspective, a shimmer sits better with our user community rather than a loading indicator.

Thank you,

Shane

I would like to draw attention to this at an early stage.
When using MAUI Nightly 8.0.20-nightly.10376, the app crashes immediately upon startup if you set Telerik Popup Settings in the MAUI Styles

See min repro example https://github.com/baaaaif/MauiNightlyCrash

<MauiVersion>8.0.20-nightly.10376</MauiVersion>

<Style TargetType="telerik:RadTimePicker">
    <Setter Property="PopupSettings">
        <Setter.Value>
            <telerik:PickerPopupSettings IsHeaderVisible="False" />
        </Setter.Value>
    </Setter>
</Style>

The Bottom Sheet component provides an intuitive way to display additional content to the users. It appears on the bottom of a screen as an overlay and presents users with a choice of actions that they must take.

Progress/Telerik --

I would like Telerik to extend the Microsoft .NET MAUI MediaPicker control to support the selection of MULTIPLE Photos and/or Videos from the Image Gallery.

I believe this is a reasonably standard scenario for use cases where the user takes multiple Photos or Videos with the Camera and then would like to upload them to a server for storage in a web app and database.

The current Microsoft MediaPicker supports the selection of a SINGLE item only.

.NET MAUI - Platform Integration - Media - Photos and Videos

And while there are several GitHub libraries that have done this for Xamarin.Forms (and rely on Xamarin.Essentials), they are either archived or not updated in a timely manner like a 3rd Party - Paid For - Control would be.

Even Telerik/Progress has recently done a Blog Post on how to use the Microsoft Control - Leomaris Reyes published this:

Getting Started with the Media Picker in .NET MAUI

Also, I believe this Feature Request is asking for the same feature:

https://feedback.telerik.com/maui/1552553-upload-images-file-via-in-net-maui

Now, for me personally, I only need multiple image selection.  So, if that's easier without the support for the other pieces, I would be happy.  To be complete, I'm thinking others would need to select multiple videos.

From Ms. Reyes Blog Post....

private async void TakePhoto(object sender, EventArgs e)
{
  FileResult photo = await MediaPicker.Default.PickPhotoAsync(new MediaPickerOptions
  {
    Title = "Select your photo"
  });
                  
  // Here, add the code that is being explained in the next step.
                   
}

The new control would have something like this:

private async void TakePhoto(object sender, EventArgs e)
{
  IEnumerable<FileResult> photos = await RadMediaPicker.PickPhotosAsync(new MediaPickerOptions
  {
    Title = "Select your photos"
  });
                  
  // Here, add the code to loop through and process the selected images
                   
}

Please let me know if you require additional information.

Hi,

Similar to WPF:   WPF DataServiceDataSource - Overview - Telerik UI for WPF

Add gRPC as an alternative to WCF.

Thanks,

Hi,

Please look  WPF EntityFrameworkCoreDataSource - Overview - Telerik UI for WPF

Although Maui has SpreadProcessing, it lacks a matching control. For the very different WPF platform you have one I use, and it would be helpful in Maui to display and readily edit class instances with numerous properties. I realize it would be a challenge to fit into mobile screens, but I do hope you will consider it, as I am trying to get all my current WPF features into my Maui work-alike. Thank you.
