I use the SDK sample - "Custoizing item" to change the item color
but when I try to get SelectedItem. it always be null. it seems it can not be selected
ItemTemplateSelector="{StaticResource ItemTemplateSelector}"
<local:CustomItemTemplateSelector x:Key="ItemTemplateSelector"
InstantItemTemplate="{StaticResource InstantItemTemplate}"
ItemWithDurationTemplate="{StaticResource ItemWithDurationTemplate}"/>
