Remarks

Dependency property identifier field: TargetProperty

You associate a Label with another control by setting the Target property. The Target is a reference to a UIElement. You can set the Target in code or in XAML. To set it in XAML, you must use an ElementName binding.

When the Target property is set, a Label inspects each DependencyProperty on the Target control for a Binding. For each Binding that is found, it inspects the Source of the Binding for metadata. The metadata can be used to set the caption text, specify whether the field is required, and specify validation rules. If the Target control has more than one Binding, you can specify the one to retrieve metadata from by setting the PropertyPath property.
