how can i do this ?

Code:

    <CustomAction RegistrationType="rt1" RegistrationId="0x010100EB674074C71B4AA7BA42EF61F36ADA2E"
    Id="CDocuemnt"
    Rights="EditListItems"
    Description="CDocument"
    ImageUrl="Version.gif"
    Title="CDocument"
    Location="EditControlBlock"
    RequireSiteAdministrator="FALSE"
    Sequence="428">
        <UrlAction Url="javascript:__doPostBack('project.Document.CDocument','{ItemId}#{ListId}');"></UrlAction>
      </CustomAction>
