public class TextEditor : Control, IAnimatable, IFrameworkInputElement, IInputElement, ISupportInitialize, IQueryAmbient, INotifier, ISearch, ITextSearch, IAutoCorrect, INotifyPropertyChanged

Remarks

TextEditor is a multiline WPF text edit control that provides text editing functionality and supports advanced text editing features. These include customizable syntax highlighting, IntelliSense, code outlining, unlimited undo/redo, bookmarks, word wrap, drag-n-drop, built-in search/replace dialogs, multiple views of the text, and more.

Here are some of the essential features provided by the editor:

IntelliSense code completion for supported languages
Code outlining (collapsible code regions)
Syntax highlighting
Errors and warnings highlighting
Code snippets
Scroll bar annotations
Search and replace
Word wrapping
Bookmarks
The gutter area with indicators
Multiple views and split view
Customizable appearance, including line styles
Printing and print preview support
Multiple selection modes
Standard editing features like undo/redo and navigation
Assortment of customizable options like whitespace display, structure guidelines, and many more

Set the Text property to specify the string collection as a single string with the individual lines delimited by a carriage return.

Use the LoadFile or LoadStream methods to load text content into the edit control.

Set the Lexer property to specify the Parser component that will perform syntax highlighting and optionally provide advanced capabilities such as code completion, code outlining, and syntax error reporting.

Examples

Here is how to declare a TextEditor from the C# code and add event handler to handle clicking on hyper-text urls.

public partial class MainWindow : Window
{
    public Form1()
    {
        InitializeComponent();
    }

    private void Window_Loaded(object sender, RoutedEventArgs e)
    {
        #region TextEditorCSharpCreation
        var edit = new Alternet.Editor.Wpf.TextEditor();
        edit.AllowOutlining = true;
        edit.Source.LoadFile("myfile.txt");
        edit.JumpToUrl += new Alternet.Editor.Wpf.UrlJumpEvent(this.edit_JumpToUrl);
        #endregion
    }

    #region TextEditorEventHandler
    private void edit_JumpToUrl(object sender, UrlJumpEventArgs e)
    {
            if (window.chbCustomHypertext.IsChecked.Value)
            {
                System.Windows.MessageBox.Show(e.Text);
                e.Handled = true;
