Context
Let`s say i have:
In layout Site.Master: 

<div class="leftColumn">
    <asp:ContentPlaceHolder ID="MainContent" runat="server" />
</div>
<div class="rightColumn">
    <% Html.RenderPartial("_Login"); %>
    <asp:ContentPlaceHolder ID="SideContent" runat="server" />
</div>

Login partialView looks like: 

<form action="/myApp/Account/Login" method="post">
    <input name="name" />Name<br />
    <input name="password" type="password" />Password<br />
    <button>Login</button>
</form>

Is it possible to update only login widget form, not the entire content page?

    If you are referring to a http post, only a post initiated (it can also be initiated by javascript) by a submit button from within the form will be posted to the server.

    If your forms are nested then this won’t work. The outer form will always post to the server.

    In the sample HTML below, clicking on the submit button on the first form will not send the values from the second form to the server. Likewise, clicking the second submit button won’t post the values from the first form.

    <html>
...
  <body> 
    <div>

      <form action="/Login/Login" method="post">
        <input type="text" name="username" value="" />
        <input type="text" name="passowrd" value="" />
        <input type="submit" name="login" value="Login" />
      </form>


      <form action="/Login/AdminLogin" method="post">
        <input type="text" name="username" value="" />
        <input type="text" name="passowrd" value="" />
        <input type="submit" name="login" value="Login Admin" />
      </form>
    </div>
</body>
</html>

    If you only wish to update/change one of the form section, then no this can not be done without using javascript and performing a javascript post(aka Ajax).
