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.

--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.
Single line folding regions is falsely recognized (by default it should be avoided) and messes up with outer regions.
For example
1 [
2 [ inner region]
3]
There should be no folding button on the inner line. Collapsing line 1 does not collapse 3 but only 1 and 2 which is wrong.
For example this custom code completion command does not fire when pressing Ctrl + Enter:
private void syntaxEditor_Loaded(object sender, RoutedEventArgs e)
{
var completionCommand = this.syntaxEditor.Commands.CodeCompletionCommand;
InputBinding keyBinding = null;
foreach (InputBinding item in this.syntaxEditor.EditorPresenter.Caret.InputBindings)
{
if (item.Command == completionCommand)
{
keyBinding = item;
break;
}
}
// unregister old key binding via Caret InputBindings
this.syntaxEditor.EditorPresenter.Caret.InputBindings.Remove(keyBinding);
// register new command in Syntaxeditor
this.syntaxEditor.KeyBindings.RegisterCommand(completionCommand, Key.Enter, ModifierKeys.Control);
}
Expected : no commented section and comment coloring in this code line
When using XML Tagger, XML Folding tagger with XML text document, the folding tagger freezes the UI while typing.
Generally in Visual Studio, the XML Folding tagger is processed in background while in SyntaxEditor this is done on the UI thread.
Several optimization options might be applied:
- process xml folding in background
- process folding similar to process search while typing - a period of inactivity time is needed to invalidate the search / folding
- caching - if the edit does not change the folding configuration, no processing and redrawing of folding is required
- some parts for extracting tooltip content and folded content should be optimized
When using LineHighlightTagger a NullReferenceException is thrown. To workaround this exception, you can add a custom TextFormatDefinition object to the TextFormatDefinitions collection of the RadSyntaxEditor.
this.syntaxEditor.TextFormatDefinitions.AddLast(LineHighlightTagger.LineHighlightFormatDefinition, new TextFormatDefinition(new Telerik.Windows.Controls.SyntaxEditor.UI.Pen(new SolidColorBrush(Colors.Gray), new Thickness(1))));
Shift + Alt + Down Selection then typing multiple characters results in all of them being typed in all selected lines.
Shift + Alt _ Down Selection then typing multiple characters results in only the first one being typed in all lines, then selection is lost and next chars are inserted in the last selected line only.
//using System;
//usign System.Windows.Controls;
Two consecutive lines with commented using sections result in ArgumentOutOfRangeException in SyntaxEditor with CSharpFoldingTagger.
/* and */ words are start /end words for multiline comments in C#/SQL/VB
They should be outside strings when they form a comment block.
Character data sections are not recognized and colored by the XmlTagger in SyntaxEditor.
