Use the ConverterParameter binding property

<TextBlock x:Name="txtContentMessage" 
    Text="{Binding Text}" 
    TextTrimming="CharacterEllipsis" 
    TextWrapping="Wrap" 
    Foreground="{Binding Entities, ConverterParameter='PUT TEXT HERE', Converter={StaticResource ChangedColorToUrlConverter}}" 
    MaxLines="3" 
    Grid.Row="1" />

Foreground="{Binding Entities,ConverterParameter={Binding Text},Converter={StaticResource ChangedColorToUrlConverter}}" Parameter is null – nogaku nogaku1987 Dec 01 '16 at 02:38
set the Mode of the binding. From the OP looked like you were referring to constant value. Made no mention of binding. – Nkosi Dec 01 '16 at 02:40
,Mode=TwoWay-> it still is null – nogaku nogaku1987 Dec 01 '16 at 02:43
On both Text binding? – Nkosi Dec 01 '16 at 02:44
ConverterParameter={Binding Text} It is a text – nogaku nogaku1987 Dec 01 '16 at 02:44
Set it on both other wise one won't know when the other changes. also you will need to let the bound Text property notify that Entities has changed in order for the binding to refresh and apply converter. – Nkosi Dec 01 '16 at 02:46
What you are tryign to achieve on the ConverterParameter cannot be done with binding http://stackoverflow.com/a/15309844/5233410 – Nkosi Dec 01 '16 at 02:50
For example to me – nogaku nogaku1987 Dec 01 '16 at 02:51
Try doing it via multibinding. that looks promising. – Nkosi Dec 01 '16 at 02:52
On UWP doest support IMultiValueConverter – nogaku nogaku1987 Dec 01 '16 at 03:03
