title: adding items to a radlistbox
body: <p>I am trying to add items from FileInfo into my RadListBox although I am not able to, I tried casting the file into a RadListBoxItem object, but I get the error that it can not convert a string to a radlistboxitem. Can someone shed a little light? thanks.</p>
  
  <pre><code>                DirectoryInfo dir = new DirectoryInfo(Path.GetFullPath(fp));
                  lb_Files.Items.Clear();
                  foreach (FileInfo file in dir.GetFiles())
                  {
                      RadListBoxItem rlb = new RadListBoxItem();
                      rlb = (RadListBoxItem)file.ToString();
                      //radListBox
                      lb_Files.Items.Add(rlb.ToString());
                  }
  </code></pre>
