How to set IsReadOnly / IsEnabled on entire container like Panel or GroupBox using XAML?

Question

I have a MVVM application that contains multiple views with some complex IsReadOnly rules based on user permissions, view/edit mode and object state.

I would like to set IsReadOnly and/or IsEnabled properties for entire groups of controls in the same container (GroupBox / StackPanel / Grid / UserControl / etc.). The value of this property will be defined in ViewModel.

I've got 3-6 different SomeGroupIsReadOnly properties per UserControl (with a large number of input controls like TextBox, RadioButtons, ComboBoxes and some DataGrids) and I'm looking for a generic, MVVM-friendly solution, that will allow me to reuse Bindings on per-container basis, instead of specifying them for each individual control separately.

How can I set IsReadOnly / IsEnabled on all controls inside container like Panel or GroupBox using XAML?

It doesn't seem that WPF supports this out of the box...

EDIT

I forgot to mention that setting IsEnabled for a container disables an important feature of TextBoxes - being able to copy their contents. I need them to be in IsReadOnly=true state. If there was a workarond for that, then my problem would be solved.

Disabling the Panel that contains your controls will also disable the controls inside the Panel. Bind the IsEnabled member of the Panel to a bool property on your ViewModel and set it according to your rules to disable the Panel and all of its children.

Xaml:

<GroupBox IsEnabled="{Binding Path=IsGroupEnabled}">
    <StackPanel>
        <Button Content="Sample Button"/>
        <TextBox Text="Sample text box"/>
    </StackPanel>
</GroupBox>
