TextArea

TextArea is a multi-line text editor with soft wrapping by default.

TextArea

Basic usage

new TextArea("Hello\nWorld");

To two-way bind to a State<string>:

var text = new State<string>("Hello\nWorld");
new TextArea().Text(text);

Find / Replace

TextArea includes a built-in Find / Replace popup:

  • Ctrl+F: Find
  • Ctrl+H: Replace

See also SearchReplacePopup.

Undo / redo

TextArea supports undo/redo:

  • Ctrl+Z: undo
  • Ctrl+R: redo

Replace operations are undoable. Replace All is recorded as a single undo step.

See Undo/Redo.

Scroll integration

TextArea implements IScrollable, so it integrates with ScrollViewer:

new ScrollViewer(new TextArea(longText));

When you bound the control (e.g. with .MaxHeight(...)) the scroll model provides an extent larger than the viewport, and the viewer can render scrollbars and synchronize offsets.

Defaults

  • Default alignment: HorizontalAlignment = Align.Start, VerticalAlignment = Align.Start

Styling

TextAreaStyle controls colors, padding, and selection rendering.
