C# wait for user to finish typing in a Text Box

Question

Is there a way in C# to wait till the user finished typing in a textbox before taking in values they have typed without hitting enter?

Revised this question a little

Ideally an inheritance solution like esskar’s is the way to go but it doesn’t play well with the designer so to get the re-use I opted for a helper style side-class:

using System;
using System.Threading;
using System.Windows.Forms;
using Timer = System.Threading.Timer;

    internal class DelayedText : IDisposable
    {
        private readonly EventHandler _onTextChangedDelayed;
        private readonly TextBox _textBox;
        private readonly int _period;
        private Timer _timer;

        public DelayedText(TextBox textBox, EventHandler onTextChangedDelayed, int period = 250)
        {
            _textBox = textBox;
            _onTextChangedDelayed = onTextChangedDelayed;
            _textBox.TextChanged += TextBoxOnTextChanged;
            _period = period;
        }

        public void Dispose()
        {
            _timer?.Dispose();
            _timer = null;
        }

        private void TextBoxOnTextChanged(object sender, EventArgs e)
        {
            Dispose();
            _timer = new Timer(TimerElapsed, null, _period, Timeout.Infinite);
        }

        private void TimerElapsed(object state)
        {
            _onTextChangedDelayed(_textBox, EventArgs.Empty);
        }
    }

Usage, in the form constructor:

InitializeComponent();
...
new DelayedText(txtEdit, txtEdit_OnTextChangedDelayed);

I haven't kicked it hard, but seems to work for me.
