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

Answer 1

As an asynchronous extension method. Adapted from Grecon14's answer.

public static class UIExtensionMethods
{
    public static async Task GetIdle(this TextBox txb)
    {
        string txt = txb.Text;
        await Task.Delay(500);
        return txt == txb.Text;
    }
}

Usage:

if (await myTextBox.GetIdle()){
    // typing has stopped, do stuff
}
