Well you need to move the IsChecked
Binding inside the Style
. Setting it directly on the Checkbox
gives it precedence and the Trigger's cannot change that value.
So something like:
<CheckBox>
<CheckBox.Style>
<Style TargetType="{x:Type CheckBox}">
<Setter Property="Margin"
Value="0,10,0,0" />
<Setter Property="Width"
Value="20" />
<Setter Property="VerticalAlignment"
Value="Center" />
<Setter Property="IsChecked"
Value="{Binding ConcentratorViewModel.Integrated}" />
<Style.Triggers>
<DataTrigger Binding="{Binding ConcentratorViewModel.Manufacturer}"
Value="ZIV">
<Setter Property="Background"
Value="Red" />
<Setter Property="IsChecked"
Value="True" />
</DataTrigger>
<DataTrigger Binding="{Binding ConcentratorViewModel.Manufacturer}"
Value="Landis+Gyr">
<Setter Property="IsChecked"
Value="False" />
</DataTrigger>
</Style.Triggers>
</Style>
</CheckBox.Style>
</CheckBox>
Note:
Remember by doing this, your Binding
only applies when the DataTrigger
's do not evaluate to "True". Thus if your Manufacturer
property is "ZIV" or "Landis+Gyr" then your Integrated
property is not going to see any CheckBox updates even with a TwoWay
binding as it just isn't being used.
