title: Is there any way to prevent form submit in MVC 5?
body: <p>I have a from.</p>
  
  <pre><code>@using (Html.BeginForm())
  {
   // From content 
   &lt;div class="form-group btn-group"&gt;
                  &lt;button type="submit" class="btnPrimaryStyle btn  col-sm-3 col-xs-12 pull-left"&gt;Save&lt;/button&gt;
              &lt;/div&gt;
  }
  </code></pre>
  
  <p>Everything is working fine. I have a dropdwon which is out of the form. I want to check, if dropdown value is selected,then form can be submitted otherwise it will not submit. In short, the dropdown selection is required and it is out of the form. I can check the value of dropdwon weather it is selected or not with jquery or javascript. My question is how i prevent to submit the form if value is not selected?</p>
