title: How to get XAML element by name stored in a string variable?
body: <p>For example, I have an UIElement:</p>
  
  <pre><code>&lt;TextBlock Name="sometextblock" Text="sample text"/&gt;
  </code></pre>
  
  <p>In the code I have a string variable with that name:</p>
  
  <pre><code>string elementName = "sometextblock";
  </code></pre>
  
  <p>How to get this element, using this variable? I need to get access to element's properties, for example, i need to be able to change a Text property.</p>
  
  <p>How to do this? </p>
  
  <p>Thank you!</p>
