title: Find UI elements in unity
body: <p>I'm facing an issue regarding UI elements in unity.</p>
  
  <p>I am making a leader board as in Piano tiles for all Facebook friends score.</p>
  
  <p>I tried instantiating UI elements at run time but cant implement. I want to assign random values to UI Text and UI images in for loop.</p>
  
  <p>I made and array of panels and and activate and deactivate them according to my requirement.</p>
  
  <p>I get the parent but I don't know how to find its children (these child are UI elements) and assign a value.</p>
