net code behind calling window.open

Using .net c# and code behind on button click gets the url from a database and tries to call javascript with variable found and open new web browser window - but code fails as no window created and error message

Error in sys.webforms.pagerequestmanagerparserexception - the message from the server could not be parsed error parsing near <script type='text/

Cannot use aspx page as dont know vlaue in that page only in code behind

Any help please!

string cUrl = "http://maps.google.co.uk/maps?ie=UTF-8&hl=en&tab=wl&q=" + cAddress;
string cScript = "<script  type='text/javascript'> window.open('" + cUrl + "');</script>";
 Response.Write(cScript);

sorry that should be using OnClientClick not AddAttributes

You could write a method in the code behind to get the Url from the database and then put that into the aspx page using AddAttributes
<asp:Button runat="Server" id="openButton" text="Open"></asp:Button>

In Page_Load:
 
string cAddress = "rgl group so51 6al";
string cUrl = "http://maps.google.co.uk/maps?ie=UTF-8&hl=en&tab=wl&q=" + cAddress;
openButton.OnClientClick = "javascript:window.Open("javascript:window.open('" + cUrl + "')";

In page load the record required is not known and it is an ajax page so not sure if page event is fired again as in ajax panel
