WPF Databinding and cascading Converters?

hi there,

i wonder if it is possible to cascade converters when using wpf databinding. e.g. something like

<SomeControl Visibility="{Binding Path=SomeProperty, Converter={StaticResource firstConverter}, Converter={StaticResource secondConverter}}"/>

is it possible at all or do i have to create a custom converter that combines the functionality of converter A and B?

• You may be looking for a solution similar to Josh Smith's "Piping Value Converters".

  In his article, he presents the following:

  <local:ValueConverterGroup x:Key="statusDisplayNameGroup">
    <local:IntegerStringToProcessingStateConverter  />
    <local:EnumToDisplayNameConverter />
  </local:ValueConverterGroup>
  

  And then uses the multi-value converters as follows:

  <TextBlock Text="{Binding XPath=@Status, 
               Converter={StaticResource statusDisplayNameGroup}}" />
  

  Hope this helps!

• You could try to use a MultiBinding, and bind twice to the same source, but with different converts on the single bindings. Something like:

  <SomeControl>
      <SomeControl.Visibility>
          <MultiBinding Converter="{StaticResource combiningConverter}">
              <Binding Path="SomeProperty" Converter="{StaticResource firstConverter}"/>
              <Binding Path="SomeProperty" Converter="{StaticResource secondConverter}"/>
          </MultiBinding>
      </SomeControl.Visibility>
  </SomeControl>
  

  Then in 'combiningConverter' you put the logic to combine the values coming from the two bindings.
