wpf update binding property on converter property change
0
I have a TextBlock which has a Foreground property bound with MultiBinding as following:
<TextBlock.Foreground>
<MultiBinding Converter="{StaticResource BlToBrshConv1}">
<Binding Path="SomePropertyOfOwnerClass" />
<Binding Path="AnotherProperty"/>
</MultiBinding>
</TextBlock.Foreground>
The converter BlToBrshConv1 is as the following:
Class BlToBrshConv1
Implements IMultiValueConverter
Property InheritedBrush as Brush
Public Function Convert(values() As Object, targetType As Type, parameter As Object, culture As CultureInfo) As Object Implements IMultiValueConverter.Convert
Try
Dim b1 As Boolean = CBool(values(0))
Dim b2 As Boolean = CBool(values(1))
If b1 = True AndAlso b2 = True Then
' Return SomeBrush0
ElseIf b1 Then
' Return SomeBrush1
Else
Return InheritedBrush
End If
Catch ex As Exception
Return InheritedBrush
End Try
Now my problem is when The property 'InheritedBrush' of the converter itself, I need to update the 'Foreground' brush.
The Foreground brush doesn't update because the bound properties ("SomePropertyOfOwnerClass" and "AnotherProperty") didnot change.
Any Ideas?

You could change the binding using triggers.
<TextBlock>
<TextBlock.Style>
<Style TargetType="TextBlock">
<Setter Property="Foreground" Value="{Binding Defaultbrush}"/>
<Style.Triggers>
<DataTrigger Binding="{Binding SomePropertyOfOwnerClass}">
<Setter Property="Foreground" Value="{Binding SomeBrush1}"/>
</DataTrigger>
<DataTrigger Binding="{Binding AnotherProperty}">
<Setter Property="Foreground" Value="{Binding InheritedBrush}"/>
</DataTrigger>
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding="{Binding SomePropertyOfOwnerClass}" Value="True"/>
<Condition Binding="{Binding AnotherProperty}" Value="True"/>
</MultiDataTrigger.Conditions>
<Setter Property="Foreground" Value="{Binding SomeBrush0}"/>
</MultiDataTrigger>
</Style.Triggers>
</Style>
</TextBlock.Style>
</TextBlock>
