Bind enabled property of WPF user control to child controls
Let's say I have a UserControl with one or more child controls on it.
How can I disable those child controls when the UserControl is disabled, and enable them when it is enabled? My UserControl does not have a ViewModel, but is simply using the code-behind because it is quite simple.
I attempted to do something like this:
<UserControl>
<ListBox IsEnabled="{Binding IsEnabled}" >
</ListBox>
</UserControl>
but it doesn't work.
c# wpf xaml

This is entirely unnecessary. When a parent element is disabled, its child elements are automatically disabled too.

@Clemens I agree totally. @ian93 Bind theUserControl
andListBox(es)

@arcticwhite No, do not bind the ListBox's IsEnabled property at all.

@Clemens Yes I agree he should not do that, but if he wants that type of solution he can do it.

On your ListBox's ItemContainerStyle
add a binding
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="IsEnabled"
Value="{Binding Path=IsEnabled,
RelativeSource={RelativeSource AncestorType=ListBox}}"/>
</Style>
</ListBox.ItemContainerStyle>
This does not answer the question, which was how to disable the ListBox when the parent UserControl is disabled. Besides that it is not necessary at all. When a ListBox is disabled, all íts ListBoxItems are disabled automatically.

I realized what my mistake was.
I was trying to bind the IsEnabled property on the instance of the UserControl to a value in my datacontext.
However, when binding to a UserControl, you have to do something like this:
IsEnabled="{Binding DataContext.IsWatermarkEnabled, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=StackPanel}}"
This solved the problem.
