When the focus gets in RadRichTextBox, AutomationProperties.Name is not pronounced by screen readers (for example by Windows Narrator).
Hi,
Since we want to boost up the performance of the ScheduleView , we've applied the 2023_2_718 UI for WPF to enable the virtualization of the group headers with setting the property IsGroupHeadersVirtualizationEnabled="True". However we've experienced issues also with rendering for the appointments and group headers(resources) when scrolling.
In one of the screens where the schedule view is used, the group headers don't have equal sizes, for example:
The height may vary depending on the overlapping appointments for the resource which is allowed for our system.
There is a note that there might be issues and unexpected behavior when the headers have different sizes claimed here:
WPF ScheduleView - UI Virtualization - Telerik UI for WPF
In this scenario we experience multiple issues, like for example when scrolled at the bottom, and the schedule view is fully refreshed, the resources and appointments are not rendered :
until it's scrolled.
Also when scrolling, we experience a "blinking" rendering, the group headers change sizes on scrolling :
Can you please let us know if/when this is planned to be fixed.
Another issue not related to the header size differences is that some of the appointments are lost (not rendered) when the height of the schedule view is changed resulting in some of the appointments to not be visible anymore .The selection is kept on the group headers, but the appointments are not rendered.
Thank you!

Using RadTabbedWindow I noticed difficulty dragging maximized windows between monitors. It seems to happen in multi-monitor environments and only when dragging Left of the PrimaryScreen.
In the video I've included , the blue window is a standard window and can be maximized in one drag across any display.
The white window is RadTabbedWindow and the drag will default to the PrimaryScreen when dragged to the left-most display.
Any help would be appreciated. Thanks
Steps to reproduce:
1. Download Telerik_UI_for_WPF_Source_[Version].zip
2. Modify the Release70 configuration to Debug70 in the following script - Build_WPF70_Xamlless.bat
3. Execute the bat file to reproduce the error:
Telerik_UI_for_WPF_Source_[Version]\Core\Controls\Input\Touch\TouchManagerV3\TouchManager.TouchMode.cs(242,9): error CS1519: Invalid token '{' in class, record, struct, or interface member declaration [D:\temp\tic\Telerik_UI_for_WPF_Source_2023_3_1114\Core\Controls\Controls_NetCore_5cmyf5ge_wpftmp.csproj::TargetFramework=net7.0-windows]
As I workaround I would suggest editing the NetCoreConfigurations.targets with the following property groups:
<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug70|AnyCPU' ">
<TargetFrameworks>net7.0-windows</TargetFrameworks>
<PlatformTarget>AnyCPU</PlatformTarget>
<DebugSymbols>true</DebugSymbols>
<DebugType>full</DebugType>
<OutputPath>bin\$(Configuration)\</OutputPath>
<DefineConstants>DEBUG;WPF;NETCORE;CODE_ANALYSIS;WPF45;WPF40</DefineConstants>

<WarningsAsErrors />
<SourceAnalysisTreatErrorsAsWarnings>true</SourceAnalysisTreatErrorsAsWarnings>
<StyleCopEnabled>false</StyleCopEnabled>

</PropertyGroup>
<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug70.NoXaml|AnyCPU' ">

</PropertyGroup> The file can be found here: Telerik_UI_for_WPF_Source_[Version]\Build\Imports\NetCoreConfigurations.targets.
Wrong XAML files are shipped with the Net Core themes archive. Instead of Docuemnts.xaml and RichTextBoxUI.xaml the RichTextBox.xaml file should be added.
When null value is provided the converter should return Visibility.Collapsed.
It is possible for a user to type a value into a RadNumericUpDown control that is greater than the maximum (or smaller than the minimum).
If the control loses focus the value reverts to the maximum value, but in my use case the user will be clicking the OK button on a Window, and this happens while the NumericUpDown still displays the out of range value that was typed. In other words the user doesn't realise that their value was silently rejected behind the scenes.
To solve this I had to raise a support request with you guys, which meant waiting until the next day for a resolution. This cost me time and it also added to your workload.
Whereas if the control had the option to limit the user input to the bounds of minimum and maximum it would have saved me about half a days work to raise a support request and write my own solution to the problem.
I see this has been raised a couple of times in the forums:
https://www.telerik.com/forums/prevent-user-from-typing-beyond-maximum-value
https://www.telerik.com/forums/radnumericupdown-lets-you-type-beyond-its-maximum-value
And the consensus seems to be that it is "By Design".
Please can you re-consider changing this as it is these small niggles that often cost us the most time when developing with 3rd party controls.
TIA

Currently PropertyDefinitions have only one Property for DataBinding, which is very strange solution.
All these instances are DependencyObject, but at the same time they are not in the visual tree and we could not bind to a visibility or to readonly or to any other property without some starnge sorkarounds (why this was designed in this way?).
This makes these objects almost useless. becuae we cannot fully use them in an MVVM way (bindings, multiibindings, etc.)
Possible solutions:
- provide bindings for all properties to make them be bindable withput any workarounds
- Change PropertyDefinitions to something that will live inside visual tree.
Currently the Windows 11 theme for Telerik WPF features the ability to switch backdrop material to Acrylic, Mica and None, but what it's missing the Mica ALT material.
Because of the substantial difference from the normal Mica material, and the ability it gives to create more modern looking applications we think that the addition of this backdrop material would greatly benefit an already very good looking theme!
When trying to install one of the following nuget packages an error occurs:
- Telerik.Windows.Controls.EntityFramework60.for.Wpf.Xaml
- Telerik.UI.for.Wpf.AllControls.Xaml (which contains the EF6 package from the previous bullet)
The same issue manifests with the NoXaml version of the same packages.
The error message is:
Severity Code Description Project File Line Suppression State Details Error Failed to add reference. The package 'Telerik.Windows.Controls.EntityFramework60.for.Wpf.Xaml' tried to add a framework reference to 'EntityFramework' which was not found in the GAC. This is possibly a bug in the package. Please contact the package owners for assistance. Reference unavailable.
A XamlParseException is raised when the theme's resource dictionaries are not merged in App.xaml. The missing resource is the RepeatButtonStyle resource.
To work this around, merge the resource dictionaries for the theme in the Resources collection of the App.xaml file.
After upgrading to .net 9 I get the following error when starting the published program (running it in RIDER in debug-mode doesn't create the issue).
System.TypeInitializationException: The type initializer for 'Telerik.Windows.Input.Touch.TouchManager' threw an exception.

the mentioned assembly System.Windows.Forms is not used by me at all.
