RegularExpression validator so my textbox have to start with uppercase
<p>I'm using this expression: </p>

<blockquote>
  <p>^[A-Z][a-zA-Z0-9]*$</p>
</blockquote>

<p>And it works fine if I type for example "Kristian". But when I want to continue that sentence like typing "Kristian is working with SharePoint", it doesn't work. Any better expression out there?</p>
