is there an event for when the contents of a text box have been highlighted.

If not is there a way to determine this.

Also is there a way to determine of a text box has been tabbed to.

You will have to mix a few events for this.

  1. Capture Left Mouse button OR Shift Key+Arrow key
  2. MouseDrag event also must be captured after that
  3. Mouse Button Up too (for the next time).

There is no event for highlighting.. but you can simulate it via the MouseUp and KeyUp events:

private void textBox_MouseUp(object sender, MouseEventArgs e) {
    if (textBox.SelectedText != "")
        MessageBox.Show("Selected!");
}

private void textBox_KeyUp(object sender, KeyEventArgs e) {
    if (textBox.SelectedText != "")
        MessageBox.Show("Selected!");
}

There is also an Enter event for when the TextBox gains focus.
