How to call a function inside the xml












0















I'm trying to call function with params within text property $parents['Page'].someFunc(itemProp) and nothing happens.
How do that?



<Repeater items="{{ myItems }}">
<Repeater.itemTemplate>
<Label text="{{ $parents['Page'].someFunc(itemProp) }}"/>
</Repeater.itemTemplate>
</Repeater>


If it's impossible, then what about case, when someFunc() is converter.

          There is a feature named converters, Your someFunc should be defined as a converter either in the bindingContext or in the application module if you want to reuse it in different pages, then you may call it from XML.



          <Repeater items="{{ myItems }}">
          <Repeater.itemTemplate>
          <Label text="{{ itemProp, itemProp | someFunc }}"/>
          </Repeater.itemTemplate>
          </Repeater>
