ScriptManager control can also be used to reference javascript files  One catch is that the ScriptManager control needs to be place inside the form tag  I myself prefer ScriptManager control and generally place it just above the closing form tag    lt asp ScriptManager ID  sm  runat  server  gt       lt Scripts gt           lt asp ScriptReference Path    Scripts yourscript min js    gt       lt  Scripts gt   lt  asp ScriptManager gt

Probably the file is not in the path specified              will move 3 step up to the directory in which the page is located and look for the js file in a folder named JS   Also the language attribute is Deprecated   See Scripts      18 2 1 The SCRIPT element      language   cdata  CI       Deprecated  This attribute specifies   the scripting language of the contents   of this element  Its value is an   identifier for the language  but since   these identifiers are not standard    this attribute has been deprecated in   favor of type    Edit  Try changing   lt script src           JS Registration js  language  javascript  type  text javascript    gt     to   lt script src           JS Registration js  language  javascript  type  text javascript  gt  lt  script gt

Use Fiddler to see what is happening  Then change the path accordingly  You will probably find you get a 404 error and the path is wrong

If your page is deeply pathed or might move around and your JS script is at    JS Registration js  of your web folder  you can try the following      lt script src   lt   ResolveClientUrl    JS Registration js     gt    type  text javascript  gt  lt  script gt

I assume that you are using MasterPage so within your master page you should have   lt head runat  server  gt       lt asp ContentPlaceHolder ID  head  runat  server  gt       lt  asp ContentPlaceHolder gt   lt  head gt    And within any of your pages based on that MasterPage add this   lt asp Content ID  Content1  ContentPlaceHolderID  head  runat  server  gt       lt script src  js yourscript js  type  text javascript  gt  lt  script gt   lt  asp Content gt
