Answer 1

It's not just HyperLinks. It seems to be more specifically TextBlock which of course is what you use to wrap a HyperLink in WPF. This will give the same issue :

<TextBlock>
    <Run Text="Barcode:"/>
    <InlineUIContainer BaselineAlignment="Center">
        <TextBox Text="{Binding OriginalPackage.BarcodeNumber}" />
    </InlineUIContainer>
</TextBlock>

I was hoping setting IsEnabled="True" would fix it but it doesn't seem to.

The easy solution is to use a StackPanel with Orientation="Horizontal"

Answer 2

I hit the same issue.

What I did is to bind HyperLink's IsEnabled to the parent, and put that in an App global resource.

<Style TargetType="{x:Type Hyperlink}">
    <Setter Property="IsEnabled" Value="{Binding IsEnabled, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type FrameworkElement}}}" />
</Style>

Answer 3

I found the answer for my case of the hyperlink not getting re-enabled, not sure if it applies to yours:

I found that when the Hyperlink's parent control is disabled (IsEnabled=false), the Hyperlink will not get notified of changes, e.g. IsEnabledChanged does not get fired, even when the bound property changes value.

My solution was to change my Xaml to no longer disable the ancestor control (which was causing the Hyperlink's parent to be disabled). With the parent (TextBlock) always enabled, now Hyperlink updates properly always.

(I'm a little bothered that the IsEnabled binding behaves differently than Controls do, and I'm not sure what I would do if I couldn't leave the ancestor enabled... but at least this lets me understand the issue I was having, and lets me work around it.)
