Changing DataTemplates in WPF with DataTriggers

posted in: Uncategorized | 0

I’ve come across a few times when I want to change the layout and contents of my screen depending on what data I have in my object. I’ve found DataTriggers really useful for this.  Based on a field being populated or not is can switch out the actual template I apply to the ContentTemplate e.g.

    <DataTemplate x:Key="clientDetails">
ContentPresenter x:Name="clientDetailsPresenter"
ContentTemplate="{StaticResource clientSummary}"
Content="{TemplateBinding Content}" />

DataTrigger Binding="{BindingClient.TFN}"Value="{x:Null}">
Value="{StaticResource clientFullDetails}" />


The other spot I find this really useful is showing different data in a list when the item is Selected.
