title: Show only Vertical scrollbar in ModalDialog window?
body: <p>I am using following code to open a modalwindow:  </p>
  
  <pre><code>function OpenPopup(rn) {
       var winargs = null;
       var winsettings = "help:no;status:no;maximize:yes;minimize:no;dialogHeight:450px;dialogWidth:820px;edge:sunken;scroll:yes;center:yes;resizable:yes;";
       winargs = window.showModalDialog("../PopUp.aspx?id=" + rn , winargs, winsettings);
  }
  </code></pre>
  
  <p>Here the property scroll provides only Yes and No option. I want only Vertical scroll bar and not Horizontal one. How should I achieve this ?</p>
  
  <p>Can anyone help me on this issue ?</p>
