EditableContentControl EditableContent property

Hello,

The default Template for the control is a good example:

<ControlTemplate TargetType="controls:EditableContentControl">
	<Grid Background="{TemplateBinding Background}">
		<ContentPresenter x:Name="presenter" Margin="2,0" Content="{TemplateBinding Content}" ContentTemplate="{TemplateBinding ContentTemplate}" 
							ContentTemplateSelector="{TemplateBinding ContentTemplateSelector}" ContentStringFormat="{TemplateBinding ContentStringFormat}">
			<ContentPresenter.Resources>
				<Style TargetType="TextBlock">
					<Setter Property="TextTrimming" Value="CharacterEllipsis" />
					<Setter Property="TextWrapping" Value="NoWrap" />
					<Setter Property="VerticalAlignment" Value="Center" />
				</Style>
			</ContentPresenter.Resources>
		</ContentPresenter>
		<TextBox x:Name="textBox" MinWidth="30" MinHeight="0" Padding="0" BorderThickness="0" FontSize="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=FontSize}" 
					Text="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=EditableContent, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" 
					TextWrapping="NoWrap" HorizontalAlignment="Left" VerticalAlignment="Center" Visibility="Collapsed" />
	</Grid>
					
	<ControlTemplate.Triggers>
		<Trigger Property="IsEditing" Value="True">
			<Setter TargetName="presenter" Property="Visibility" Value="Collapsed" />
			<Setter TargetName="textBox" Property="Visibility" Value="Visible" />
		</Trigger>
	</ControlTemplate.Triggers>
</ControlTemplate>

You can see there how the TextBox is swapped in when IsEditing=true.  In a cloned ControlTemplate, you could replace the TextBox with some other control if you wish.
