c# - How to switch between views using DataTemplate + Triggers -


i have requirement where user can switch view hierarchical data either tree or text in datagrid or flowchart.

the user can clicking toggle button say: switch mode. want in such way can handled within view viewmodel in 3 cases same.

how apply view viewmodel based on trigger.

if state of view show saved in enum property use contentcontrol , datatriggers example:

<contentcontrol>     <contentcontrol.style>         <style targettype="{x:type contentcontrol}">             <style.triggers>                 <datatrigger binding="{binding viewmode}" value="treemode">                     <setter property="content">                         <setter.value>                             <uc:treemodeview />                         </setter.value>                     </setter>                 </datatrigger>                 <datatrigger binding="{binding viewmode}" value="gridmode">                     <setter property="content">                         <setter.value>                             <uc:gridmodeview />                         </setter.value>                     </setter>                 </datatrigger>             </style.triggers>         </style>     </contentcontrol.style> </contentcontrol>

(as style used in 1 place, setting directly contentcontrol.style work, if want use in more 1 place should set contenttemplate instead, because otherwise there 1 view instance shared controls style not allowed wpf (of course content needs set something template applied))

you bind directly ischecked of togglebutton using elementname of course. relevant values true, false , {x:null}.
