title: ASP.Net Alert is disappearing after few seconds
body: <p>I'm displaying BootStrap alert in my MVC application. Here is an alert code snippet.</p>
  <pre><code>&lt;div class=&quot;row&quot;&gt;
        &lt;div class=&quot;col-md-12&quot;&gt;
          &lt;div class=&quot;alert alert-success alert-dismissible d-none&quot; id=&quot;age-category-message&quot; role=&quot;alert&quot; aria-atomic=&quot;true&quot;&gt;
          &lt;/div&gt;
        &lt;/div&gt;
      &lt;/div&gt; 
  </code></pre>
  <p>the alert shows only upon action and disappears after few seconds,
  I want to display it for some more time, so how can I extend the default disposal time of the bootstrap alert?</p>
