title: Is PostbackUrl equivalent to Form.Submit?
body: <p>I inherited an application that used forms to POST data.  I am not very familiar with Form behavior. To me, this is an arcane method of doing a POST.  Plus, these forms break hardcore when converted to MasterPages because of <a href="https://stackoverflow.com/questions/597596/how-do-you-overcome-the-html-form-nesting-limitation">Forms Nesting.</a></p>
  
  <p>So I am refactoring, trying to minimize the dmg I'm doing.  Are these two functionally equivalent?</p>
  
  <p><strong>Original method</strong></p>
  
  <pre><code>&lt;form id="transferForm" action="TransferSave.aspx" method="post"&gt;
  &lt;input type="button" id="Button2" class="button" onclick="transferForm.submit();" value="Review Transfer"/&gt;
  </code></pre>
  
  <p><strong>New way</strong></p>
  
  <pre><code>&lt;asp:Button ID="submitBtn" runat="server" class="button" Text="Review TransferX" PostBackUrl="TransferSave.aspx" /&gt;
  </code></pre>
  
  <p>I tested the new method and it worked.  I just want to be sure that what I am doing doesn't create some nutty problem that I am unaware of.  Mainly because I just don't feel like a master of html forms.</p>
