c# - Storyboards can't find ControlTemplate elements -

i've created simple xaml, , works (at least in kaxml). storyboards run when called within xaml, when try access them outside error:

'buttonglow' name cannot found in name scope of 'system.windows.controls.button'. 

i loading xaml stream reader, this:

button x = (button)xamlreader.load(stream); 

and trying run storyboard with:

storyboard pressedbuttonstoryboard =        storyboard)_xamlbutton.template.resources["buttonpressed"]; pressedbuttonstoryboard.begin(_xamlbutton); 

i think problem fields animating in template , storyboard accessing button.

here xaml:

finally found it. when call begin on storyboards reference elements in controltemplate, must pass in control template well.

changing:

pressedbuttonstoryboard.begin(_xamlbutton); 

to:

pressedbuttonstoryboard.begin(_xamlbutton, _xamlbutton.template); 

fixed everything.
