I am trying to get a TreeView to look kind of "grayed out" and disable the use of it on a boolean being true. The issue I am having is the current layout of the XAML seems to be preventing this and I am having a hard time finding a way around it.
This is the layout of the XAML I'm using and am not sure how/if I can pass the Parent's DataContext down into the DataTemplate:
<Grid>
<TreeView>
<TreeView.ItemTemplate>
<DataTemplate x:DataType="ViewModelObject">
<TreeViewItem ItemSource="{x:Bind Children" Content="{x:Bind Name}"/>
</DataTemplate>
</TreeView.ItemTemplate>
</TreeView>
</Grid>
What I would like to do is to add a field of Foreground to the TreeViewItem to change the color based off a variable in the ViewModel, but the DataTemplate having a separate DataContext is preventing this.
If there are other ways to make it have that "grayed out" disabled look, I would also love advice there, this is just the best way I came up with.
The easiest way is to use {Binding} instead of {x:Bind}, that will let you use the ElementName property to get the page (give it an x:Name first) and from there you can navigate to your ViewModel property and to whatever you need out of it.
