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.

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".

Steps to Reproduce:
--Install Bopomofo or Quick input method (Traditional Chinese).
--Open the Telerik SyntaxEditor in a WPF application.
--In any text input field, enter an Alt code (e.g., Alt+0160 for a non-breaking space).
--Attempt to type any Chinese characters immediately after entering the Alt code.

Current Behavior:
  -Bopomofo IME:
    -- The user cannot type any Chinese characters after entering an Alt code.
    -- Switching the language (e.g., pressing Shift) allows English input, but Chinese input remains blocked.

Quick IME:
   -The input method automatically switches to English after entering an Alt code.
   -The language indicator still shows Chinese, but characters typed are in English.
   T-o resume Chinese input, the user must click another text field, alt-tab to another window, then return.

Expected Behavior:
   -Users should be able to continue typing Chinese characters after entering Alt codes without needing to manually switch inputs.
   -The IME state should remain consistent, allowing uninterrupted input.

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).

(The issue might be similar to: https://feedback.telerik.com/wpf/1670420-typeinitializationexception-in-telerik-windows-input-touch-touchmanager-with-net-9 )

We are using the RadRichTextbox limiting the width size and configured to wrap the text, automatically increasing its height as needed. While this functionality works correctly for most text, it fails in cases where a line ends with spaces. These trailing spaces extend beyond the control's visible boundaries, making them invisible on-screen, yet they remain present in the RadDocument.

To reproduce: Create a RadRichTextbox with limited width and auto adjusted height. Type in underlined text on first line and add a lot of spaces that go behind the visible width. Type in more text to see the visible underlined text go to the next line (while hiding the added underlined spaces of the previous line). Exporting to RadDocument shows the extra underlined spaces that RadRichTextbox does not.

If a RadDocking has its theme set to Windows 11 via the StyleManager.Theme attached property, placing a RadGridView inside (styled with a different theme, such as Office_Black, Summer, etc.) will cause its cells to look merged after performing an edit operation.

As a workaround, the RowHeight and the FontSize properties of the RadGridView instance can be used to resolve this.

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();

The current implementation of the Code128 symbology class used with RadBarcode throws an InvalidSymbolException for characters with codes greater than 127.

As you can see from this table, there are many special characters in Code128 that have larger codes:

https://en.wikipedia.org/wiki/Code_128#Bar_code_widths

It would be useful to have these in applications which need to modify a reader device's behavior with barcode control characters in order to communicate properly.

It seems that the first time a Center TextAlignment is applied to the selection, its length is cached. Because of this, when the selection content (text) changes the length is not updated, thus the text doesn't align properly. It aligns accord to the initial length of the context. The content doesn't update also if the alignment is reset.

 

To work this around, avoid the FlowNoWrap layout mode and use only Flow.

Fixed in Telerik.Licensing NuGet package version 1.4.10. Install this (or later) version of the package to avoid the issue.

Build errors may occur in situation where you have two projects one depending on the other, and the main project installs the Telerik.Licensing nuget package. The package triggers a set of MSBuild taks and at some point an IncrementalClean is invoked, which deletes some of the files and errors occur during the build.

The error message that can occur:

The issue seems related to an animation timing problem in combination with the internal usage of the ObjectAnimationUsingKeyFrames class instead of BooleanAnimationUsingKeyFrames.

The exception message is:

To work this around, you can extract the ControlTemplate of RadBusyIndicator and replace the ObjectAnimationUsingKeyFrames that animates the ContentControl.IsEnabled property with a BooleanAnimationUsingKeyFrames.

 

	<BooleanAnimationUsingKeyFrames BeginTime="00:00:00" Duration="00:00:00.001" Storyboard.TargetName="Content" Storyboard.TargetProperty="(Control.IsEnabled)">

				<sys:Boolean>False</sys:Boolean>
			</DiscreteBooleanKeyFrame.Value>
		</DiscreteBooleanKeyFrame>
	</BooleanAnimationUsingKeyFrames>
