Presently I am doing it like this. But when I put an extension into a .js file and add it to the head section and then try to use it elsewhere, it complains 'it is not a constructor', so then I have to paste the extension code just above where I need to use it and it works. This is how my head section and Script Manager Looks like currently :
<head id="Head1" runat="server">
<title>Clinicians Home</title>
<link rel="stylesheet" type="text/css" href="CSS/mainstyle.css" />
<link rel="stylesheet" type="text/css" href="JavaScript/ext-resources/css/ext-all.css" />
<script type="text/javascript" src="JavaScript/ext-adapter/ext/ext-base.js"></script>
<script type="text/javascript" src="JavaScript/ext-all.js"></script>
<script type="text/javascript">
Ext.util.CSS.swapStyleSheet("theme", "JavaScript/ext-resources/css/xtheme-gray.css");
</script>
<script type="text/javascript" src="JavaScript/DataStore.js" ></script>
<script type="text/javascript" src="JavaScript/GlobalConstants.js" ></script>
<script type="text/javascript" src="JavaScript/GenericType.js"></script>
<script type="text/javascript" src="JavaScript/RowExpander.js"></script>
<script type="text/javascript" src="JavaScript/PanPanelExtension.js" ></script>
<script type="text/javascript" src="JavaScript/OrganisationEntity.js"></script>
<script type="text/javascript" src="JavaScript/Library.js"></script>
<script type="text/javascript" src="JavaScript/TypeMappings.js" ></script>
<script type="text/javascript" src="JavaScript/JsonRpc.js"></script>
<script type="text/javascript" src="JavaScript/json.js"></script>
<script type="text/javascript" src="JavaScript/RpcTreeLoader.js"></script>
<script type="text/javascript" src="JavaScript/NavTree.js"></script>
<script type="text/javascript" src="JavaScript/form-handlers.js"></script>
</head>
<body>
<form id="form1" runat="server">
<ext:ScriptManager ID="ScriptManager1" Theme="Gray" runat="server">
<Listeners>
<DocumentReady Handler="NavTree.init();" />
</Listeners>
</ext:ScriptManager>
Please suggest any possible optimisation. thanks
