How to autoload a partial view on a page?

Question

.NET

@{
ViewBag.Title = "AdminPanel";
}

Admin Panel

<div>
    @using (Ajax.BeginForm("Groups", new AjaxOptions { UpdateTargetId = "results" , LoadingElementId = "loading" }))
    {
        <input type="submit" class="btn btn-default" value="Groups" />
        
    }

</div>
   
    <div id="results">

    </div>

    <div id="loading" style="display:none; color:green; position:center; font-weight:bold;">
        <p>Идет загрузка данных, ожидайте...</p>
    </div>
</div>

in the view, I made the loading of the partial view on button click, but how can I make the partial view load automatically when the page is refreshed?
