Question

I am creating a custom control and was wondering if it is possible to render any JavaScript in the head tags of the page it is placed on? I am thinking I would need to use the FindControl method, but am not sure what I need to bind to. I am thinking the page object? Let me know if I am thinking in the right direction or if there is another option.

My only concern with the above mentioned idea is that how do I render all my content while placing some code in the head tags?

Thanks

protected override void OnPreRender(EventArgs e) {
    base.OnPreRender(e);

    string includeTemplate = "<link rel='stylesheet' type='text/css' href='{0}' />\n";
    string includeLocation = Page.ClientScript.GetWebResourceUrl(GetType(), "Path.To.Resources.css");
    LiteralControl include = new LiteralControl(String.Format(includeTemplate, includeLocation));
    Page.Header.Controls.Add(include);
}

I use this in my control-library to include css and javascript-files.
