Change Data Template dynamically

1. Attached Property bound to task State. Any change will dynamically set data template.
2. Visual State Manager

 

ADataTemplateSelectorDoes not respondPropertyChangeEvents, so it doesn' t get re-evaluated when your properties change.

The alternative I use isDataTriggersThat changesTemplateBased on a property.

For example, this will draw allTaskModelObjects usingContentControl, AndContentControl.TemplateIs based onTaskStatusProperty ofTaskModel

<DataTemplate x:Key="OpenTaskTemplate" TargetType="{x:Type local:TaskModel}">     <TextBlock Text="I‘m an Open Task" /></DataTemplate> <DataTemplate x:Key="ClosedTaskTemplate" TargetType="{x:Type local:TaskModel}">     <TextBlock Text="I‘m a Closed Task" /> </DataTemplate><DataTemplate DataType="{x:Type local:TaskModel}">     <ContentControl Content="{Binding }">         <ContentControl.Style>             <Style TargetType="{x:Type ContentControl}">                 <!-- Default Template -->                 <Setter Property="ContentTemplate" Value="{StaticResource OpenTaskTemplate}" />                 <!-- Triggers to change Template -->                 <Style.Triggers>                     <DataTrigger Binding="{Binding TaskStatus}" Value="Closed">                         <Setter Property="ContentTemplate" Value="{StaticResource ClosedTaskTemplate}" />                     </DataTrigger>                 </Style.Triggers>             </Style>         </ContentControl.Style>     </ContentControl> </DataTemplate>
