<statusbaritem dockpanel.dock="left" margin="0,2,0,0">     <textblock text="{binding statusmessage}"                 margin="5,0,0,0"                 foreground="white">         <textblock.style>             <style targettype="textblock">                 <style.triggers>                     <datatrigger binding="{binding systemisready,                                             notifyonsourceupdated=true,                                             mode=twoway}"                                   value="false">                         <datatrigger.enteractions>                             <beginstoryboard>                                 <storyboard>                                     <doubleanimation storyboard.targetproperty="opacity"                                                           from="1.0"                                                            to="0.5"                                                            duration="0:0:1.5"/>                                 </storyboard>                             </beginstoryboard>                         </datatrigger.enteractions>                     </datatrigger>                     <datatrigger binding="{binding systemisready,                                             notifyonsourceupdated=true,                                             mode=twoway}"                                   value="true">                         <setter property="opacity" value="1.0"/>                     </datatrigger>                 </style.triggers>             </style>         </textblock.style>     </textblock> </statusbaritem>

the test method changes text , updates issytemready if status equal 'ready'. binding working animation fade 0.5 opacity seems have fired before application shown , trigger set opacity 1 not working.

why animation/trigger not re-firing?

thanks time.

the animation not re-firing because timeline still running, have stop storyboard allow value reset.

you can use stopstoryboard this, name storyboard call stopstoryboard in enteractions of true datatrigger

example:

<textblock.style>     <style targettype="{x:type textblock}">         <style.triggers>             <datatrigger binding="{binding systemisready, mode=twoway, notifyonsourceupdated=true}"  value="false">                 <datatrigger.enteractions>                     <beginstoryboard name="fadeout">                         <storyboard>                             <doubleanimation storyboard.targetproperty="opacity" from="1.0"  to="0.5"  duration="0:0:1.5"/>                         </storyboard>                     </beginstoryboard>                 </datatrigger.enteractions>             </datatrigger>             <datatrigger binding="{binding systemisready, mode=twoway, notifyonsourceupdated=true}" value="true">                 <setter property="opacity" value="1.0"/>                 <datatrigger.enteractions>                     <stopstoryboard beginstoryboardname="fadeout" />                 </datatrigger.enteractions>             </datatrigger>         </style.triggers>     </style> </textblock.style>

Today I want to introduce you to two very powerful small business advertising options created by Google. These two ingenious programs have all but revolutionized the way advertising is done on the web.
