</style>

i trying assign style by

    var temp= (style)application.current.resources["customscrollviewerstyle"];     this.style = temp;

here getting value of temp variable null "customscrollviewerstyle". when use "custombuttonstyle" getting style object. why there difference in these 2 styles, both of them placed in same file(app.xaml)? or issue within "customscrollviewerstyle". did noticed these kind of issue earlier?

note

this ported code windows phone 8.
