title: How to refresh the Labels and other controls inside the GroupBox/Panels inside a Form in C#?
body: <p>I'm designing a C# application where I have a groupbox showing OS and RAM related information. 
  I designed it using the controls - labels put together in a Groupbox showing RAM related information. </p>
  
  <p>I have a Refresh button which when clicking should display % of RAM used currently.</p>
  
  <p>For this, I need the label (and also few other labels) inside the groupbox to <strong>refresh and re-compute the value.</strong> </p>
  
  <p>How do i do this? I tried all below in the RefreshButton_Click event but nothing works:</p>
  
  <pre><code>label1.Refresh(); 
  
  GroupBox1.Refresh(); 
  
  Form1.Refresh(); 
  Form1.Invalidate(true); 
  
  Panel1.Refresh();
  </code></pre>
  
  <p>Pls help in this as I do not think reloading an entire form would an efficient solution. </p>
