Is there a security reason to validate a textbox input if you are limiting the max length of the input?
<p>Since I'm new to coding and I'm trying to understand why here is a little more detail on the question.</p>

<p>If you have a text box and you are limiting the input to say 2 charactrs do you really need to validate the input further? </p>

<p>What I have is a text box that has a max length of 2.  Is there a security reason to add a validator to the textbox.  I should add this is in Asp.net.</p>
