On a wpf TextBox that has an TextChanged event, it seems to only fires when focus is taken away from the textbox; but not as individual characters

    @Anron answer is correct but i think it works only when we are doing Data binding (using MVVM).

    From @thecorp question what i have understood is he is trying to it in code behind file.

    You can take advantage of "KeyDown" and "KeyUp" events of textbox or if you are using data binding Aaron anwer should resolve your issue.
