Why do not the events on the two buttons work? Do you have to do something specific to work?

    My guess is BindingContext.
    This is a template for Items out of a collection. All the properties are on the ELEMENT of the COLLECTION, right? Like the text and so on.

    That would include the command.
    <iconize:IconButton Text="md-place" Command="{Binding ShowMapaCommand}"
    In this binding the command and the text are expected to come off the same object.

    Is the command on the element of the collection? or is it someplace higher up, like on the ViewModel?

    My Page is linked to a ViewModel, and in the viewmodel there is the command.

        public ICommand ShowMapaCommand { get; }
        public ProdutoViewModel(Produto prod)
                    Produto = prod;
                    ShowMapaCommand = new Command(ExeShowMapaCommand);
    private void ExeShowMapaCommand()

    and in the viewmodel there is the command.

    Okay. Like I said... Your command is in the VIewModel but you're template would be looking at the element in your collection just like it does for all the other properties.

    Clint StLaurent, Thank you, really. I created the command inside my object and it worked perfectly!

  • Can You Share how you created the command inside your object
