Question

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 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.
