string SelectionDirection { get; }

Gets the direction in which selection occurred. This is "forward" if selection was performed in the start-to-end direction of the current locale, or "backward" for the opposite direction.

int SelectionEnd { get; set; }

Gets or sets the index of the end of selected text. If no text is selected, contains the index of the character that follows the input cursor. On being set, the control behaves as if setSelectionRange() had been called with this as the second argument, and selectionStart as the first argument.

int SelectionStart { get; set; }

Gets or sets the index of the beginning of selected text. If no text is selected, contains the index of the character that follows the input cursor. On being set, the control behaves as if setSelectionRange() had been called with this as the first argument, and selectionEnd as the second argument.

int TextLength { get; }

Gets the codepoint length of the control's value.

string Type { get; }

Gets the type (textarea).

string Value { get; set; }

Gets or sets the value.

string Wrap { get; set; }

void Select(int selectionStart, int selectionEnd, string selectionDirection = null)

Selects a range of text, and sets selectionStart and selectionEnd. If either argument is greater than the length of the value, it is treated as pointing to the end of the value. If end is less than start, then both are treated as the value of end.

void SelectAll()

Selects the contents of the textarea.
