I´d like to reuse a MultiBinding and tried to use this solution, but I can´t seem to reach IsEnabled from a Setter Property.
So I tried this approach, but no cigar :
App.xaml
<Application x:Class="Test.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:model="clr-namespace:Test.MODEL"
StartupUri="MainWindow.xaml">
<Application.Resources>
<view:BooleanConverter x:Key="BooleanConverter" />
<view:BooleanMultiConverter x:Key="BooleanMultiConverter" />
<MultiBinding x:Key="OnOffBinding" Converter="{StaticResource BooleanMultiConverter}" ConverterParameter="OR">
<Binding Path="model:CustomerIsDefined" Converter="{StaticResource BooleanConverter}" />
<Binding Path="model:CustomerIsConfirmed" Converter="{StaticResource BooleanConverter}" />
</MultiBinding>
</Application.Resources>
MainWindow.xaml > These two attempts will not compile :
<TextBox IsEnabled="{StaticResource OnOffBinding}"/>
<TextBox IsEnabled="{MultiBinding {StaticResource OnOffBinding}}" />
Any ideas?
EDIT: After accepting Funcs answer I guess this has allready been answered in the linked thread. Sorry..

Try wrapping it in Style
<Application.Resources>
<view:BooleanConverter x:Key="BooleanConverter" />
<view:BooleanMultiConverter x:Key="BooleanMultiConverter" />
<Style x:Key="ControlEnabler" TargetType="Control">
<Setter Property="IsEnabled">
<Setter.Value>
<MultiBinding x:Key="OnOffBinding" Converter="{StaticResource BooleanMultiConverter}" ConverterParameter="OR">
<Binding Path="model:CustomerIsDefined" Converter="{StaticResource BooleanConverter}" />
<Binding Path="model:CustomerIsConfirmed" Converter="{StaticResource BooleanConverter}" />
</MultiBinding>
</Setter.Value>
</Setter>
</Style>
</Application.Resources>
MainWindow.xaml
<TextBox Style="{StaticResource ControlEnabler}"/>
Note TargetType="Control"
making it generic.
