When using a screen reader on Android, iOS, WinUI, the reader do not reach the pdf document. Provide option for screen reader support.

The Issue:

When interacting with the SlideView on a Windows touch device and having ScrollView as a child element:

Actual Behavior: Once the user swipes inside the ScrollView using a touch gesture, the SlideView loses control of the touch gestures and never regains it. This leaves the user unable to swipe between slides.

Expected Behavior: Swiping gestures should seamlessly transition between scrolling the content within the ScrollView and navigating the SlideView.

Environment Details:

Platform: Windows
Control: Telerik SlideView with ScrollView as child elements
Touch Device: Windows touch-enabled hardware

When creating a .NET MAUI blank net 9 template and adding for example PDF toolbar, the toolbar icons do not display as the app is build as unpackaged.

Solution:

Change the package type in the .csproj file:

from: 
<WindowsPackageType>None</WindowsPackageType>

to:
<WindowsPackageType>MSIX</WindowsPackageType>

When a picker is in a modal page, the picker isn't displaying over the modal page.  It is showing up on the page behind it. This happens to any picker control e.g. Date, List etc.

The ItemsSource of the views is populated in the ViewModel of the page. This is done in a command that is triggered by the NavigatedTo event of the page, which is forwarded via EventToCommandBehavior from the Maui Toolkit.

When using the RadCollectionView the loaded items are no longer displayed. 

When the ObservableCollection of the items is completely reconstructed and reassigned the display works.

Navigating to a DataGrid that is placed on third page first time the control displays when navigating to the third page. When navigating back to the second page and then go back to the third page the control do not display. 

On net 8 works as expected, the issue happens on net 9 and singleton approach is used.

When having the following setup:

and the style is defined as follow:

it works with 7.1.0 version

Dear Telerik-Team

with the new version 9.0.0 on Android the Scheduler doesn't display the Date/Timepicker on creating/editing an new appointment. The Date/Timepicker Popup is only displayed when the "EditAppointmentDialog" is closed. You can easy reproduce it. Just add the Scheduler to a plain project.

I have attached a VS solution where you can reproduce it.

Thanks for helping/fixing it as soon as possible. I need this new version becasue of another bugfix for scheduler in it...

"System.IO.FileNotFoundException: 'Could not load file or assembly 'Microsoft.Maui.Controls.Compatibility, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.'"

Occurs when creating a blank .net maui project using .net9 and adding Telerik MAUI NuGet Package latest version 8.0.0

Repro steps:

1. Create a new dotnet9 basic project in visual studio.
2. Launch it on windows. it runs.
3. Add the Telerik.UI.for.Maui.Trial package, version 8. (don't bother adding the UseTelerik line to MauiProgram.cs, it'll fail either way).
4. Clean and Rebuild the solution.
5. Debug the app on windows again. It fails on launch with a file not found error that seems to relate to:
"Exception thrown: 'System.IO.FileNotFoundException' in Telerik.Maui.Controls.Compatibility.dll"
System.IO.FileNotFoundException: 'Could not load file or assembly 'Microsoft.Maui.Controls.Compatibility, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.'

See simple example baaaaif/CollectionViewFilterIssue (MainPage.xaml.cs) to reproduce, click hide and show

When items are filtered through a FilterDescriptor they are hidden - correct
Trying to show the previously hidden items they don't appear again as expected - bug

I've used a BooleanFilterDescriptor and a DelegateFilterDescriptor, both don't work.

Stops me from using the RadCollectionView control
