title: Customizing OpenFileDialog
body: <p>I am working on winforms application in C#. What I want to achieve is to get a file from user for which I am using the following code: </p>
  
  <pre><code>OpenFileDialog dlg = new OpenFileDialog();
  if (dlg.ShowDialog() == DialogResult.OK)
  {
      string sFileName = dlg.FileName;
      //my code goes here
  }
  </code></pre>
  
  <p>Now, everything is working fine but I want to put 3 radio buttons in the same dialog box, meaning I would now get two things from this dialog box</p>
  
  <pre><code>string sFileName = dlg.FileName; //same as in case of traditional dialog box
  //some thing like this which tells which radio button is selected:
  dlg.rbTypes.Selected
  </code></pre>
  
  <p>How do I achieve this?</p>
