    Hi,

    I'm a little confused here: I was trying to use generic Find.ByAutomationId<T> method that is supposed to return me actually FrameworkElement object for now (the same as non-generic method returns), but it returns me null. Though when I use non-generic sibling (Find.ByAutomationId) it seems to be working fine. Any ideas why it might happen? Cast problems? I was wondering if the method actually returns anything if it can't cast, but well, non-generic works. The element is definitely present in the xaml structure and has correct automation id (as proved by non-generic method once again).

    Thank you,
    Artem

    So, none has any ideas? the controls it looks for inherit IFrameworkElement. Non-generic works fine, but it's not suitable...

    Hello Artem,

    The cast could be the problem. The framework finds an element with the specified attribute, however if the cast fails it will stop the search and return null.
