title: Why do I have 2 different required field validation popups
body: <p>I have 2 different pages, each with a form on them.</p>
  
  <p>now one page if I leave a required field empty I get these validation popups:
  <a href="https://i.stack.imgur.com/RVzGr.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/RVzGr.png" alt="enter image description here"></a></p>
  
  <p>This is the code of the image above:</p>
  
  <pre><code>&lt;div class="form-group"&gt;
      &lt;p class="control-label col-md-5"&gt;&lt;i class="fa fa-exclamation-triangle triangle" aria-hidden="true"&gt;&lt;/i&gt; &lt;b&gt;Voorletter(s)&lt;/b&gt;&lt;/p&gt;
      &lt;div class="col-md-4"&gt;
          @Html.EditorFor(model =&gt; model.Voorletters, new { htmlAttributes = new { @class = "form-control", required = "required", placeholder="K" } })
          @Html.ValidationMessageFor(model =&gt; model.Voorletters, "", new { @class = "text-danger" })
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>but on the other I get a popup, which if you ask me has the same code:</p>
  
  <p><a href="https://i.stack.imgur.com/2K5XC.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/2K5XC.png" alt="enter image description here"></a></p>
  
  <pre><code>&lt;div class="form-group"&gt;
      &lt;p class="control-label col-md-5"&gt;&lt;i class="fa fa-exclamation-triangle triangle" aria-hidden="true"&gt;&lt;/i&gt; &lt;b&gt;Functie&lt;/b&gt;&lt;/p&gt;
      &lt;div class="col-md-4"&gt;
           @Html.EditorFor(model =&gt; model.Functie1, new { htmlAttributes = new { @class = "form-control", required = "required" } })
           @Html.ValidationMessageFor(model =&gt; model.Functie1, "", new { @class = "text-danger" })
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p><strong>but I would prefer the latter option, how do I always get that?</strong></p>
  
  <p>Is the latter validation message a chrome standard?</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>earlier I tried to change the first validation message "This field is required" by making a metaclass, but that only changed the text. </p>
  
  <pre><code>[MetadataType(typeof(medewerkerMetaData))]
  public partial class medewerker
  {
      public partial class medewerkerMetaData
      {
        //[Required(ErrorMessage = "Verplicht invullen!")]
          public string Voorletters { get; set; }
  
        // more code
      }
   }
  </code></pre>
