title: Textbox will not accept if you input first a " "
body: <p>I have 2 question. First,  i have a <code>TextBox</code> named <code>Student Name</code>. My problem is that when i press <kbd>Space</kbd> the value in my <code>TextBox</code> will be <code>" "</code>. And then when i press <kbd>Save</kbd> button it save in my DB. </p>
  
  <p>Well the condition I make in my textbox is it will not save if theres no text but since it has a value <code>" "</code> its accepted. And the second is that you must not input <code>"space first before letter"</code>. Example if you enter <code>" John"</code> it will display a message that  says: <code>"Theres no name that starts with space!"</code> well something like that ... </p>
