#1,184 – Where Data Templates Are Used, part II
October 21, 2014 Leave a comment
A data template is typically set as the value of the ContentTemplate property of a ContentControl or the ItemTemplate property of an ItemsControl.
The ContentTemplate and ItemTemplate properties are typically used as follows:
- The ContentTemplate is used as the ContentTemplate of a ContentPresenter, which is itself contained in the control’s control template
- The ItemTemplate is used as the ContentTemplate for each item presented by an ItemsPresenter (e.g. used as ContentTemplate for a ListBoxItem).
Below is a fragment of the default control template for a Label. You can see that it contains a ContentPresenter that has its ContentTemplate set to the ContentTemplate of the parent control.
<ControlTemplate TargetType="{x:Type Label}"> <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" SnapsToDevicePixels="True"> <ContentPresenter ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" ContentStringFormat="{TemplateBinding ContentStringFormat}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/> </Border> <ControlTemplate.Triggers> <Trigger Property="IsEnabled" Value="False"> <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate>
