title: Using onblur jquery function to check validation data after submit POST?
body: <p>I use <code>$("#User_Username").on("blur", function ()</code> to check valid user for <code>UserNameTextBox</code> in my Vie. And another field in my form, i use the default validation of ASP MVC to valid, such as Textbox, DropdownList. </p>
  
  <p>The jquery validation works fine. My main problem is when user click on <code>Register</code> button (they dont care whether or not the value on <code>UsernameTextbox</code> valid, just click) , if another filed is not valid, it return the form and show error message.</p>
  
  <p>At this case,, my valid status on <code>UsernameTextbox</code> lost, i have to click to this textbox to event <code>onblur</code> fire again.
  Any suggestion? I have tried to disable <code>Register</code> button until <code>UserNameTextBox</code> valid, but it is more solution for my validation.</p>
