Conditional DataTemplate

Question

Here is what I am trying to do. I have 2 Data Templates defined which both refer to a different user control.

Answer 1

Don't set the ItemTemplate but use an ItemTemplateSelector.

DataTriggers would be fine too of course, spares you the extra class for the selector. e.g.

<ItemsControl.ItemTemplate>
    <DataTemplate>
        <ContentControl Content="{Binding}">
            <ContentControl.Style>
                <Style TargetType="ContentControl">
                    <Style.Triggers>
                        <DataTrigger Binding="{Binding ThatProperty}" Value="1">
                            <Setter Property="ContentTemplate"
                                    Value="{StaticResource myDataTemplate1}" />
                        </DataTrigger>
                        <DataTrigger Binding="{Binding ThatProperty}" Value="2">
                            <Setter Property="ContentTemplate"
                                    Value="{StaticResource myDataTemplate2}" />
                        </DataTrigger>
                    </Style.Triggers>
                </Style>
            </ContentControl.Style>
        </ContentControl>
    </DataTemplate>
</ItemsControl.ItemTemplate>
