DependencyObject::SetValue Method (DependencyPropertyKey, Object)
Sets the local value of a read-only dependency property, specified by the DependencyPropertyKey identifier of the dependency property.
Assembly: WindowsBase (in WindowsBase.dll)
This signature is generally used when you set values for read-only dependency properties that are defined by your custom classes. Generally, SetValue is called only from the type that registered that dependency property, which implements the internal logic that provides the determined value for the dependency property. For more information, see Read-Only Dependency Properties.
If the provided type does not match the type that is declared for the dependency property as it was originally registered, an exception is thrown. The value parameter should always be provided as the appropriate type. The exception conditions are potentially influenced by the ValidateValueCallback callback that exists on the dependency property identifier of the dependency property being set.
The following example defines a read-only dependency property, along with a public static readonly DependencyProperty that provides necessary read-only exposure to property consumers, and the get accessor for the CLR wrapper.
