Add spellcheck as you type feature.

When the EditorFontFamily is set to SegoeUI the RadSyntaxEditor can be placed over letters when changing it position.

Currently the Caret of the SyntaxEditor does not behave like Caret in MS TextBox/ RichTextBox when IME is opened - IME opens on the bottom right part of the screen instead of below the caret. Also some input issues when selection is done in the IME should be addressed for a full support of this feature.

Add dependency property for showing/hiding the line numbers on the left of the source code.

We could introduce API for customizing the folding region lines and their respective regions. For example, a customization could be hover-coloring of line regions, like in the latest VS:

Add support for successful typing text with IME - Chinese, Japanese, Korean etc.
Currently there are input issues, selection issues, caret issues when using IME input.

Localize the tooltips for the match case button, the match word button and the use regular expression button.

Currently, the tooltips of the buttons are using hardcoded strings in English.

To translate the tooltips, you can get the corresponding buttons on load of the syntax editor control and replace their tooltips manually.

Searching "windows" in the text "Windows Windows Windows" with option MatchCase highlights all windows which is wrong - no highlight should be performed

An exception is thrown when the RadSyntaxEditor is disabled with the Expression_Dark theme being applied with StyleManager.

Good morning,

can You implement in one of the next releases the regex and case sensitive search? I provided you the Visual Studio 2019 search screenshot

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.

Enter key is improperly handled internally and this results in inability to use the key in combination with other modifier keys for custom commands.

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);
        }

string link = "https:////_a_w_e_bsite.com" will falsely recognize a commented section and color it in CSharpTagger
Expected : no commented section and comment coloring in this code line

Big text with many lines or lines long enough to cover the viewport height when wrapped with word wrapping break the virtualization mechanism in RadSyntaxEditor. This makes the scrolling and resizing performance slow.

The UI becomes irresponsive when using XmlFoldingTagger with a large XML file.

Add ability to disable horizontal scrollbar and enable word wrapping - fixed width of editor and if the word cannot fit - it is moved to next line.

The completion list appears transparent when the Material theme is applied.

Expose API to control the FontWeight and FontStyle of the highlighted words.

Currently, the RadSyntaxEditor control does not have an out-of-the-box printing functionality.

Add functionality for precise positioning of the popups inside the RadSyntaxEditor control.
