How to pass to the Converter Parameter something that is not hard coded

问题

Something like:

 <TextBlock Text="{Binding Text,Converter={StaticResource
  ccc},ConverterParameter=PersonName}"/>

when Person name is Property of the class for example.

Update:

I've seen a solution that tells to inherit from DependencyObject and to implement IValueConverter. I want to know if there is something simpler.

回答1:

The answer is straight-forward, but not what you want to hear.

You can only target a binding at DependencyProperty on a DependencyObject. Binding does not inherit from DO, so you can't binding the converter parameter.

If you want other state passed into a converter, you may have to subclass the desired obect and add new properties

回答2:

Have you looked into MultiBinding? If you want two properties sent to the converter, like "Text" and "PersonName" you may be able to do something like this:

<TextBlock>
  <TextBlock.Text>
    <MultiBinding Converter="{StaticResource ccc}">
      <Binding Path="Text"/>
      <Binding Path="PersonName"/>
    </MultiBinding>
  </TextBlock.Text>
</TextBlock>

This assumes that "Text" and "PersonNames" are properties on the DataContext. You may need to change the binding paths if that's not the case.
