    Frankly I'm asking this one only because I'm curious.  

    I have a fairly conventional RadGrid set up with edit links on each row.  Each link calls a JavaScript function which in turn causes an editing screen popup.  

    The link elements look like this:  
    <a id="ctl00_MainContent_RadGrid1_ctl00_ctl04_EditLink" href="#" onclick="return EditForm('14001','0');">Edit</a>

    I also have a span at the top of the page that displays "Welcome" logged in person.  Somehow someone messed up the users table and the name field included characters within double quotes.  As such, for example, the field would be rendered like this:
      <span id="lblFullName" style="color:Blue;">Welcome Joe "***" Smith</span>

    When this happened, the JavaScript function started crashing. The function got the correct parameters but this line started crashing.
     var oWnd = window.radopen("EditForm.aspx?Id=" + Id, "Edit Item " + Id); 

    When I put a catch in there, the error was Cannot read property 'open' of undefined.

    Naturally the practical solution to this problem was to purge the database of bad data but I'd still like to know what happened.

    Hi Boris,

    I am afraid I am not sure when the JavaScript throws an error. How the double quotes in the span element are connected with the script which opens the EditForm? I would appreciate if you could provide a small runnable sample in order to investigate the cause for this issue further.
