DependencyObject.ClearValue Method (DependencyProperty)

Clears the local value of a property. The property to be cleared is specified by a DependencyProperty identifier.

Namespace:  System.Windows
Assembly:  WindowsBase (in WindowsBase.dll)

member ClearValue : 
        dp:DependencyProperty -> unit 

Parameters

dp
Type: System.Windows.DependencyProperty
The dependency property to be cleared, identified by a DependencyProperty object reference.

ExceptionCondition
InvalidOperationException

Attempted to call ClearValue on a sealed DependencyObject.

Clearing the property value by calling ClearValue does not necessarily give a dependency property the default value that is specified in the dependency property metadata. Clearing the property only specifically clears whatever local value may have been applied. For more information, see Dependency Property Value Precedence.

The following example iterates all properties that have local values set on an object, then calls ClearValue to clear the values of each such property.
