    I have a telerikDataControls:RadListView.ItemTemplateSelector working nicely. 

            AllDayTemplate="{StaticResource AllDayCellTemplate}"
            InspirationTemplate="{StaticResource InspirationCellTemplate}"
            ErrorTemplate="{StaticResource ErrorCellTemplate}">


    The templates are in separate files like this:

    <?xml version="1.0" encoding="utf-8"?>
    <?xaml-comp compile="true" ?>
        <DataTemplate  x:Key="ErrorCellTemplate">
                    <Label Text="ERROR"></Label>


    Problem: I need to call an ICommand on the parent Page from the Cell. How do I reference the page? I tried to give the page a x:Name and try that in the Binding on the Cell, but the compiler throws an error that it can't find the Page.

    The cell, if placed in the main page works fine, but the cells are huge so I want them in separate files to manage.

    TappedCommand="{Binding Source={x:Reference MyPage}, Path=BindingContext.EventDetailCommand}"

    Hi Ivan,

    The Xamarin.Forms framework does not support this. You'll need either need to to redesign the approach so that the x:Reference is available in scope of the ContentPage, or place the Resources area below the content area (so that it is out of your way).

    For example:

            ...your content
            ... your resources
