body: <p>As the title suggests,
  Is there a way to check if a "Dynamically" created Button inside a Gridview has caused a Postback.
  As there are more than one button in page!</p>
  
  <p>I have tried the following: </p>
  
  <pre><code>String ButtonID = Page.Request.Params["__EVENTTARGET"];
  String ButtonID = Request.Form["__EVENTTARGET"];
  String ButtonID = Request.Params["__EVENTTARGET"];
  </code></pre>
  
  <p>But these all return Null value.
  I need to identify the button created Dynamically inside the GrdiView.</p>
