Question

Well i guess it’s easy my scenario is having 2 elements:
ListBox and Button:

<ListBox Name="BannedItemsListBox"
         Margin="5"
         MinWidth="100"
         MaxWidth="100" " Height="
         204" ItemsSource="{Binding Path=BannedItems, Mode=TwoWay}"></ListBox>
<Button Name="RemoveBannedItemsButton"
        Margin="5"
        MinWidth="65"
        Height="22"
        Click="RemoveBannedItemButton_Click">Remove</Button>

I want to bind the IsEnabled property button to be true only if Item from ListBox is selected (focused) in XAML

I tried

IsEnabled="{Binding ElementName=BannedSourcesListBox, Path=TouchesDirectlyOver.Count}"

but no go.

Answer 1

What does the selection have to do with the Touches? (Also the ElementName is off)

I would try this:

IsEnabled="{Binding SelectedItems.Count, ElementName=BannedItemsListBox}"

Explanation: Basically the binding system tries to convert the input to the property at hand, a boolean, so when it gets an integer, 0 will be converter to false, anything higher to true. So the Button will be enabled if one or more items are selected.
