title: Changing a Button's Content with another Button
body: <p>With this code I managed to change its own content:</p>
  <pre><code>public void Button1_Click(object sender, RoutedEventArgs e)
  {
     Button button1 = sender as Button;
     button1.Content = &quot;Something&quot;;
  }
  </code></pre>
  <p>But how can I change it's content with another button?</p>
  <p>I tried:</p>
  <pre><code>public void Button2_Click(object sender, RoutedEventArgs e)
  {
     Button1.Content = &quot;Something2&quot;;
  }
  </code></pre>
  <p>But this time I have to click the <code>Button1</code> first then the second to make it work.</p>
