Is PostbackUrl equivalent to Form.Submit?

Question

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 Forms Nesting.

So I am refactoring, trying to minimize the dmg I'm doing. Are these two functionally equivalent?

Original method

<form id="transferForm" action="TransferSave.aspx" method="post">
<input type="button" id="Button2" class="button" onclick="transferForm.submit();" value="Review Transfer"/>

New way

<asp:Button ID="submitBtn" runat="server" class="button" Text="Review TransferX" PostBackUrl="TransferSave.aspx" />

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.

Answer 1

Is some different... At First PostBackURL does post to the same page and then redirects sending the form values, but not only the values you desired, ALL CONTROLS are sended...
