The operating system region and language needs to be set to Japanese.

RichTextBox seems to have several issues with Japanese, but being locked from visibility or edit is the biggest one.

To recreate, start typing in Japanese, push the "right" arrow after selecting the IME option desired, then hit "spacebar." This seems to duplicate the text, then when trying to continue to type into the text field the text is no longer visible (yet the IME does display).

The native WPF RichTextBox has no issues (and also supports partial selection, etc.).

I've attached a video to show the behavior with 2025 Q1 telerik.

*note:* This is on a machine with NVIDIA graphics. I mention this as there may be some issues with RichTextBox and the hardware... When I'm in a virtual machine with a completely Japanese environment and virtual graphics driver, there is NO text visible at all when trying to type into the RichTextBox. Works fine with other controls and wpf RichTextBox.

Currently, the RadFileDialogs do not support setting filters without specifying the extensions for the files. This is deemed an incorrect filter pattern and an exception is raised.

We can provide support for filtering files that do not have an extension.

MF_E_SHUTDOWN error occurs in some cases when the camera MediaFoundation resources get released. This may happen on unloaded or initialized of the RadWebCam control.

Here is one of the exception stacktraces that may be observed:

Currently, the DataFormatString property of the columns is applied only to the top-level rows and not to the child ones.

To work this around, create a new DataTemplate for the CellTemplate property of the column and set the StringFormat property of the Binding instance for the element that will be used to display the cell's value in view mode.

<telerik:GridViewDataColumn.CellTemplate>
    <DataTemplate>
        <TextBlock Text="{Binding MyPropertyValue, StringFormat=N2}"/>
    </DataTemplate>
</telerik:GridViewDataColumn.CellTemplate>

NullReferenceException occurs when the the automation peers creation for the rows goes over 10,000 peers (the MaxCachedPeersSize setting of the GridViewDataControlAutomationPeer). The exception occurs only when the 'record' modifier is used in the class definition. For example:

public record class MyClass(int Id)
{
}

The exception stacktrace is:

System.NullReferenceException: 'Object reference not set to an instance of an object.'
peer was null.
Telerik.Windows.Controls.GridView.dll!Telerik.Windows.Automation.Peers.GridViewDataControlAutomationPeer.ClearPeer(Telerik.Windows.Automation.Peers.DataItemAutomationPeer peer)   Telerik.Windows.Controls.GridView.dll!Telerik.Windows.Automation.Peers.GridViewDataControlAutomationPeer.GetOrCreateItemPeer(object item, int index) Line 288 C#  Telerik.Windows.Controls.GridView.dll!Telerik.Windows.Automation.Peers.GridViewRowAutomationPeer.FindDataItemAutomationPeer(System.Collections.Generic.List<System.Windows.Automation.Peers.AutomationPeer> childPeers) Telerik.Windows.Controls.GridView.dll!Telerik.Windows.Automation.Peers.GridViewRowAutomationPeer.GetChildrenCore() 

.

To work this around use the "class" modifier instead of "record". For example, instead of:

public record class MyClass(int Id)
{
}

Use:

public class MyClass
{
    public int Id { get; set; } 
}

 Or alternatively, increase the MaxCachedPeersSize value.

When the DropDownPlacement property of the RadDropDownButton element is set to Top and the Windows 11 theme is used, a Setter in the default ControlTemplate tries to set the VerticalOffset of the drop-down Popup element. This is done via a converter (of the type of MultiplyValueConverter), to which a "-1" is passed as a ConverterParameter. In the Convert method of the converter, the native System.Convert.ToDouble method tries to convert the ConverterParameter to the type of double. Internally, the Convert.ToDouble method uses the current culture when converting a string to a double.

This is observed when using a different culture, for example, "ar-EG".

The CSharpTagger matches the following character combination as a multiline comment start - / * (slash and a start with a whitespace between). This causes wrong tags creation in scenarios where the * character is a part of a single line comment. The correct comment start and end should be /* and */.

In the following example, the beginning of the first single line comment is considered a multiline comment start, but since nothing closes it, the entire text is tagged and colored as a comment.

// ***********************************************************************
// some other content here
// some other content here

Distinct values are not displayed when setting the FilterMemberPath to the Date property of a DateTime DataTable column when it contains DBNull.Value.

Generally, this is present because while the distinct values are generated, we check for the Date property in each row, however, when it reaches a row that has a DBNull.Value value, an exception is thrown because the Date property cannot be found in null.

NullReferenceException is thrown when the RadVirtualKeyboard control gets loaded, but it is not added to the visual tree. This skips the initialization of an internal collection which is used on Loaded, thus throwing the error.

To work this around, you can manually call the OnApplyTemplate method of RadVirtualKeyboard before it gets loaded.

virtualKeyboard.OnApplyTemplate();

When the TitleBarVisibility is Collapsed, the backstage close button is aligned with the top of the backstage adorner. The button should have a top margin applied. 
This reproduces when the BackstagePosition property of RadRibbonBackstage is set to Office2013, which is the default setting of newer Telerik themes.

To work this around, get the backstage close button and set its top margin.

 private void RadRibbonBackstage_Loaded(object sender, RoutedEventArgs e)
 {
     var backstage = (RadRibbonBackstage)sender;
     var closeButton = backstage.FindChildByType<RadRibbonButton>();
     closeButton.Margin = new Thickness(closeButton.Margin.Left, 15, closeButton.Margin.Right, closeButton.Margin.Bottom);
 }
