Question

I have a style for a ItemContainer that is based on the Item being contained (With a StyleSelector). It works fine. However on runtime the property might be changed but the style isn’t updated instantly.

Is there anyway for me to get it to update as soon as the changes are saved?

Answer 1

Use a DataTrigger and a Converter which returns the Type of an object

For example,

<Style.Triggers>
    <DataTrigger Binding="{Binding Converter=ObjectToTypeConverter}" 
                 Value="{x:Type local:Person}">
        <Setter Property="ItemTemplate" Value="{Binding PersonTemplate}" />
    </DataTrigger>
    <DataTrigger Binding="{Binding Converter=ObjectToTypeConverter}" 
                 Value="{x:Type local:Business}">
        <Setter Property="ItemTemplate" Value="{Binding BusinessTemplate}" />
    </DataTrigger>
</Style.Triggers>
