WPF more then one DataTrigger -


would know why xaml below not working. looks can not have more 1 datatrigger element. storyboards within datatrigger, can tell being executed on button click. end reason on button click, 1 grid should slide up, , other slide down, achieving sort of accordian animation.

</grid>                  </grid>              </stackpanel>

the "ispressed" lets know when button "active" changes again when release button.

have tried moving command binding on button , set properties on viewmodel grids can use set styles on themselves?
