ASP.NET masterpages: how to insert markup in the head section inside the aspx?

I know I can access the head section of a page which uses a masterpage programmatically this way (in code behind):

This is only an example (I'd like to insert scripts and styles etc.):

this.Header.Title = "I just set the page's title";

Is there a simple way to do this in a declarative way on in the aspx file itself?

Sometimes it would be handy to insert a client script or a style declaration or a link to an external resource.

Solution

  • You can do this by using content regions in the head, in exactly the same way as you would in the body of the page. eg, In your masterpage:

    <head>
    <link type="text/css" rel="stylesheet" href="/styles/common1.css" />
    <script type="text/javascript" src="/scripts/common1.js"></script>
    <asp:contentplaceholder id="ExtraStylesAndScripts" runat="server" />
</head>

    And then in the page itself just something like:

    <asp:content contentplaceholderid="ExtraStylesAndScripts" runat="server">    
    <link type="text/css" rel="stylesheet" href="/styles/extra1.css" />
    <link type="text/css" rel="stylesheet" href="/styles/extra2.css" />
    <script type="text/javascript" src="/scripts/extra1.js"></script>
    <script type="text/javascript" src="/scripts/extra2.js"></script>
</asp:content>
