wpf - One out of two buttons using same ControlTemplate does not animate -

i have listview uses datatemplate render out each item, each item having edit , remove button. 2 buttons templated use path display icon, , animate storyboard when mouse on happens.

the animation changes opacity , trigger used add dropshadow effect on mouseover. problem have despite 2 buttons sharing same templates, 1 of them has desired behavior of animating when moused on regardless if listviewitem selected not. 2nd 1 (the edit button) not animate unless first select it's listviewitem.

images demonstrate

untouched listview: trash can (remove) works properly, while edit highlighted. moving mouse on edit button results in none of animations playing.

in state, listviewitem not have mouse on it, there no mouseover effects (change of color etc) shown.

mouse on over remove button: remove button continues work expected. highlighting on mouse on effect.

in state (and following states), listviewitem has mouseover it, causing styling reflect it.

selecting listviewitem lets edit animation start working: when select listviewitem, edit button goes ahead , starts animate right.

animations working w/ selected listviewitem: can see edit button lighting when moused over.

i'm not sure why 2 buttons, sharing same template act differently.

the listview

this listview, using adminquantlistattributetemplate, rendering out content see in above pictures.

<listview dockpanel.dock="top"             margin="5 0 0 0"             x:name="attributeslistview"             itemssource="{binding path=attributesview}"              itemtemplate="{staticresource adminquantlistattributetemplate}"             selecteditem="{binding path=selectedattribute}"/> 

the itemtemplate

this item template contains 2 buttons in question. have tried re-organize them, remove button first. not matter in order put buttons in xaml, edit button continues broken until listviewitem selected.

the buttonicontemplate

this template buttons using. note using template in multiple locations through-out app , works fine. used in groupbox , expander headers, datagrid columns multiple buttons , stand-alone controls. when used within listview (only place in app using this), not work.

any in troubleshooting awesome.

edit

it turns out edit button had canexecute method returning false (which expected). when have canexecute return true always, animation works right.

so question is, how let storyboard stuff work, when button disabled?

i guess problem editattributecommand.canexecute returns false , prevents being animated. thing differs 2 buttons, that's why guess.
