Remarks

SyntaxEdit is a multi-line WindowsForms 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)
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
Stream and Block selection modes
Multi-level undo/redo
Whitespace display

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 Lexer property to specify 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 SyntaxEdit from the C# code and add event handler to handle clicking on hyper-text urls.

public partial class Form1 : Form
{
    private void Form1_Load(object sender, EventArgs e)
    {
        var syntaxEdit1 = new Alternet.Editor.SyntaxEdit(this.components);
        syntaxEdit1.Dock = System.Windows.Forms.DockStyle.Fill;
        syntaxEdit1.LoadFile("myfile.txt");
        syntaxEdit1.HyperText.HighlightHyperText = true;
        syntaxEdit1.JumpToUrl += new Alternet.Editor.UrlJumpEvent(this.SyntaxEdit1_JumpToUrl);
    }

    private void SyntaxEdit1_JumpToUrl(object sender, UrlJumpEventArgs e)
    {
        if (chbCustomHypertext.Checked)
        {
            MessageBox.Show(e.Text);
            e.Handled = true;
        }
    }
