title: Get selected Object from Combobox
body: <p>I have this <code>Combobox</code> filled with objects
  And Upon selecting a certain object from the <code>combobox</code> I would like to show Text in a <code>Textbox</code>, but for some reason I can't get my selection through.</p>
  
  <p>This is what is in my <code>combobox</code>:</p>
  
  <pre><code> private void showBirds()
      {
          cboBirds.Items.Clear();
          foreach (Bird b in Bird.ReadBirdCSV(txtFile.Text))
          {
              cboBirds.Items.Add(b);
          }
      }
  </code></pre>
  
  <p>It basically shows the names of birds from the Objects Bird.</p>
  
  <pre><code> private void cboBirds_SelectionChanged(object sender, SelectionChangedEventArgs e)
          {
  
  //WHAT DO I WRITE HERE TO GET txbGender TO SHOW THE GENDER?
  
          foreach (Bird b in cboBirds.Items)
          {
              Console.WriteLine(b.Gender +" - " + b.Name +" - " + b.Risk + " - " +b.Reference);
          }
  //^This shows all info on every bird.
  
      }
  </code></pre>
  
  <p>I'm sure it's really simple, I just can't seem to figure it out.</p>
