Invoked when the value of the Content property changes.


protected virtual void OnContentChanged(
  object oldContent, 
  object newContent
)

oldContent

Type: System.Object [.NET] | Platform::Object [C++]

The old value of the Content property.

newContent

Type: System.Object [.NET] | Platform::Object [C++]

The new value of the Content property.

If a value for ContentTemplateSelector exists, then the default implementation calls SelectTemplate on the implemented DataTemplateSelector, passing the newContent value as item, and the calling ContentControl as container. The return value then sets ContentTemplate automatically on the caller.
