I have a group of the button mui:LinkGroup which contains four buttons mui:Link which one I disactivate it and remain in gray.
Here is my code with Xaml and C#
<mui:LinkGroup DisplayName="{x:Static p:Resources.Link_Transport}" x:Name="transport">
<mui:LinkGroup.Links>
<mui:Link DisplayName="{x:Static p:Resources.Link_Moyens_Transport}" Source="/Pages/Transports/ListTransport.xaml" />
<mui:Link DisplayName="{x:Static p:Resources.Link_Voyages}" Source="/Pages/Voyages/ListVoyage.xaml" />
<mui:Link DisplayName="{x:Static p:Resources.Link_Allottement}" Source="/Pages/Allottement/EffecterSiege.xaml" />
<mui:Link DisplayName="{x:Static p:Resources.Link_Etat_Voyages}" Source="/Pages/Transports/TransportTravels.xaml" />
</mui:LinkGroup.Links>
</mui:LinkGroup>
I do not like to completely remove the button or put it in comment and thank you in advance for help :)
