Programmatically adding Javascript File to User Control in .net

Question

How do you add Javascript file programmatically to the user control?

I want the user control to be a complete package - ie I don't want to have to add javascript that's related to the user control on the page where it's used, when I can do it inside the control itself.

Since there is no Page object in the user control, how would you do it?

Answer 1

In the Page_Load method of control.ascx.cs file:

LiteralControl jsResource = new LiteralControl();
jsResource.Text = "<script type=\"text/javascript\" src=\"js/mini-template-control.js\"></script>";
Page.Header.Controls.Add(jsResource);

HtmlLink stylesLink = new HtmlLink();
stylesLink.Attributes["rel"] = "stylesheet";
stylesLink.Attributes["type"] = "text/css";
stylesLink.Href = "css/mini-template-control.css";
Page.Header.Controls.Add(stylesLink);

This will load css and Javascript into the head tag of the main page, just make sure that the head has runat="server".

You can register client script includes using the ClientScriptManager. Page is accessible through the Control.Page property.

Page.ClientScript.RegisterClientScriptInclude (
  typeof ( MyControl ), "includeme.js", "js/includeme.js"  );

EDIT: Sorry, for a total "complete package", its possible using scripts as Embedded Resources, and aquire dynamic URL's through the WebResource.axd handler. If this is not considered totally complete, then i guess it could be put in App_LocalResources, but it never gonna be just one file, unless the code and script is inline.
