I am in the process of preparing my product for alpha release and I am scrubbing my log files for anything that needs to be cleaned up prior to release. I am seeing two message in my log file that I cannot pinpoint in my code so I am suspecting it is coming from your code. I use NLog to log errors so I format Errors differently than general errors. I am seeing the following two errors being logged on app startup:

----------------------------------In my MauiProgram.cd file, I load many fonts:
_ = builder
.UseMauiApp<App> ()
.UseTelerik ()
.ConfigureFonts (fonts => {
_ = fonts.AddFont ("FontAwesome6Brands-Regular-400.otf", "FaBrands");
_ = fonts.AddFont ("FontAwesome6Duotone-Solid-900.otf", "FaDuotone");
_ = fonts.AddFont ("FontAwesome6Pro-Light-300.otf", "FaLight");
_ = fonts.AddFont ("FontAwesome6Pro-Regular-400.otf", "FaRegular");
_ = fonts.AddFont ("FontAwesome6Pro-Solid-900.otf", "FaSolid");
_ = fonts.AddFont ("FontAwesome6Pro-Thin-100.otf", "FaThin");
_ = fonts.AddFont ("OpenSans-Regular.ttf", "OpenSansRegular");
_ = fonts.AddFont ("OpenSans-Semibold.ttf", "OpenSansSemibold");
_ = fonts.AddFont ("Poppins-Black.otf", "PoppinsBlack");
_ = fonts.AddFont ("Poppins-BlackItalic.otf", "PoppinsBlackItalic");
_ = fonts.AddFont ("Poppins-Bold.otf", "PoppinsBold");

.ConfigureMobyApplication ();As you can see, 'Assets/Fonts/Segoe UI.ttf' or 'Assets/Fonts/Segoe UI.otf' is a font I am loading. In fact, all of the 'Segoe' font names use a dash '-' instead of a space in the file name. Also, I only load 'ttf' fonts and not 'otf' fonts for Seqoe fonts. Telerik controls are the only non-standard controls I am using so I am suspecting this font name is being loaded by your controls somehow. Can you please confirm this?
Also, when I went to report this incident, I noticed that you had requested input from me on previous issues I have raised, but I never received any email from you requesting this information. Since I rarely log into this website for anything, I don't know how you expect people to answer your questions if they are not made more visible. Is there a way to subscribe to an issue so I see all updates? I looked over the complete set of items I can add to this issue and none of them seem to be related to answering questions from you. It would be helpful for you to send any and all updates on any issues that have been logged. I just scanned my entire set of email folders and other than messages from your sales department, no other messages were found. Just sayin'...
Asking for a webview which opens external links ( links with a target= element) in the same webview instead of it does do nothing onbios and android, but in windows opens it a browser window with that url of the link!
we need the functionality to overrule the target= function of a link. To the same webview. At this moment we need a hybridwebview functionality! And it would be very handy to have that in a telerik control!

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
I recently migrated my code from Xamarin.forms to MAUI.
RadListView.GetDataView now always returns null in MAUI , its working fine in Xamarin.forms.
I am trying to close all the groups while loading, but facing a null exception with DATAVIEW
protected override void OnAppearing()
{
base.OnAppearing();
try
{
//collapse all
var dataView = MyRadListView.GetDataView();
dataView.CollapseAll();}}
If this worked in earlier releases, it no longer does.
Using iOS Simulator (set to iPhone 15 iOS 17.4) - with a DataGrid as below, double-clicking the text cell will crash the app. I have not yet tried on a native device build (not simulator.)

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

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.
