StringBuilder sb = new StringBuilder();
     sb.AppendLine(@"<script type=""text/javascript"">");
     sb.AppendLine(@"function deleteOwnerRow(rowId)");
     sb.AppendLine(@"{");
     sb.AppendLine(string.Format(@"{0}.Delete({0}.
        GetRowFromClientId(rowId));", OwnersGrid.ClientID));
     sb.AppendLine(@"}");
     sb.AppendLine(@"</script>"); 

Bad example - Hard to read ?the string is surrounded by rubbish + inefficient because you have an object and 6 strings

     string.Format(@"<script type=""text/javascript"">                  
       function deleteOwnerRow(rowId)                    
      { {0}.Delete({0}.GetRowFromClientId(rowId)); } </script> ", 
       OwnersGrid.ClientID);                                    

Good example Slightly easier to read ?but it is 1 code statement across 10 lines

     string scriptTemplate = Resources.Scripts.DeleteJavascript;
     string script = string.Format(scriptTemplate, OwnersGrid.ClientID); 

     <script type=""text/javascript"">
     function deleteOwnerRow(rowId)
     {
            {0}.Delete({0}.GetRowFromClientId(rowId));
     }
     </script> 

Figure: The code in the first box, the string in the resource file in the 2nd box. This is the easiest to read + you can localize it eg. If you need to localize an Alert in the javascript

Figure: Add a recourse file into your project in VS2005

Figure: Read value from the new added resource file
