Definition

Namespace:
Microsoft.UI.Xaml.Controls
Edit

Invoked when the value of the Content property changes.

protected:
 virtual void OnContentChanged(Platform::Object ^ oldContent, Platform::Object ^ newContent) = OnContentChanged;
void OnContentChanged(IInspectable const& oldContent, IInspectable const& newContent);
protected virtual void OnContentChanged(object oldContent, object newContent);
function onContentChanged(oldContent, newContent)
Protected Overridable Sub OnContentChanged (oldContent As Object, newContent As Object)

Parameters

oldContent
Object

Platform::Object

IInspectable

The old value of the Content property.

newContent
Object

Platform::Object

IInspectable

The new value of the Content property.

Remarks

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.
