title: Check if button has been submitted
body: <p>i have a page with multiple forms like this: (all of them have different names</p>
  
  <pre><code> &lt;form method="post" name="form1"&gt;
      &lt;input type="text&gt;
      &lt;input type="text&gt;
      &lt;input type="text&gt;
      &lt;input type="text&gt;
      &lt;button type="submit" name="button1" class="btn btn-icon btn-primary glyphicons circle_ok"&gt;&lt;i&gt;&lt;/i&gt;Save changes&lt;/button&gt;
   &lt;/form&gt;
  </code></pre>
  
  <p>This is the code i'm using to check which form is submitted:</p>
  
  <pre><code>if(IsPost &amp;&amp; !Request["button1"].IsEmpty()) {  
  
  } 
  </code></pre>
  
  <p>the code above  only works if i submit the form through an <code>&lt;input type="submit" name="button"&gt;</code>
  i wanted to know if there's any way to know which form is submitted with a button type=submit (the one that's in the form i posted above)</p>
