title: C# Custom textBox design
body: <p>I want to customize a textBox in C# and I have a problem. If I set</p>
  
  <pre><code> textBox1.BackColor = Color.Transparent 
  </code></pre>
  
  <p>I receive error: </p>
  
  <blockquote>
    <p><code>Additional information: Control does not support transparent background colors.</code> </p>
  </blockquote>
  
  <p>I tried to insert in constructor </p>
  
  <pre><code>SetStyle(ControlStyles.SupportsTransparentBackColor, true); 
  </code></pre>
  
  <p>but didn't solve anything. I have installed Dev Express but I don't know if it helps. Some ideas?
  Constructor:</p>
  
  <pre><code>public Constructor()
          {
              this.SetStyle(ControlStyles.SupportsTransparentBackColor, true);
              InitializeComponent();
          }
  </code></pre>
