stretch="uniformtofill" height="50"/> </contentcontrol> </grid> </controltemplate> </setter.value> </setter> </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.
