title: ASP.NET :: During page_load, how can I get the ID of the control that submitted the postback?
body: <p>During the Page_Load, I would like to capture the control that performed the postback.</p>
  
  <pre><code>protected void Page_Load(object sender, EventArgs e)
  {
      if (!Page.IsPostBack)
      {
  
      }
  
      // Capture the control ID here.
  }
  </code></pre>
  
  <p>As usual, any ideas would be greatly appreciated!</p>
