windows store apps - How to change VisualState Setter property via code in C#? -

i have following visualstate setter properties in uwp app.

 <visualstatemanager.visualstategroups>         <visualstategroup x:name="visualstategroup">             <visualstate x:name="desktop">                 <visualstate.statetriggers>                     <adaptivetrigger minwindowwidth="800" />                 </visualstate.statetriggers>                 <visualstate.setters>                     <setter target="desktopads.visibility" value="visible" />                     <setter target="desktopads.(grid.row)" value="0" />                     <setter target="desktopads.(grid.column)" value="4" />                     <setter target="desktopads.(grid.columnspan)" value="1" />                     <setter target="mainscrollviewer.(grid.row)" value="0" />                     <setter target="mainscrollviewer.(grid.column)" value="2" />                     <setter target="mediacontrol.height" value="600" />                      <setter target="mobileads.visibility" value="collapsed" />                     <setter target="mainscrollviewer.(grid.columnspan)" value="1" />                  </visualstate.setters>             </visualstate>             <visualstate x:name="phone">                 <visualstate.statetriggers>                     <adaptivetrigger minwindowwidth="0" />                 </visualstate.statetriggers>                 <visualstate.setters>                     <setter target="desktopads.visibility" value="collapsed" />                      <setter target="mediacontrol.height" value="400" />                      <setter target="desktopads.(grid.row)" value="1" />                     <setter target="desktopads.(grid.column)" value="0" />                     <setter target="desktopads.(grid.columnspan)" value="3" />                      <setter target="mobileads.visibility" value="visible" />                     <setter target="mainscrollviewer.(grid.row)" value="0" />                     <setter target="mainscrollviewer.(grid.column)" value="0" />                     <setter target="mainscrollviewer.(grid.columnspan)" value="5" />                 </visualstate.setters>             </visualstate>         </visualstategroup>     </visualstatemanager.visualstategroups> 

i want have trial , paid version of app trial version having ads , paid version without ads. using licenseinformation.istrial property determine whether app trial or paid version , when app loading making visibility of desktopads , mobileads collapsed. because of adaptivetriggers desktopads , mobileads visibility gets changed visible , still see ads. how make visibility permanently collapsed in paid version of app?

what want use visual state groups. this:

<visualstatemanager.visualstategroups>     <visualstategroup x:name="layoutvisualstategroup">         <visualstate x:name="desktop" />         <visualstate x:name="phone" />             </visualstategroup>     <visualstategroup x:name="advertvisualstategroup">         <visualstate x:name="showads" />         <visualstate x:name="hideads" />             </visualstategroup> </visualstatemanager.visualstategroups> 

then, let adaptive triggers handle layout, , let code-behind handle hiding , showing adverts. because put states groups, mutually exclusive, , can set indep. sort of how button can both pressed , enabled. groups. typical approach, way.

best of luck!
