Setting the SwipeState of the SwipeView from the view model has no effect if the left and right content has not been displayed.

I debugged the source code and found that it was because _leftContainer.Bounds and _rightContainer.Bounds were not calculated if they were not displayed before.

I modified ProcessSwipe as follows, then it works as expected.

    private void ProcessSwipe(SwipeState state)
    {
        switch (state)
        {
            case SwipeState.RightVisible:
                _rightContainer.IsVisible = true;
                MaterializeDataTemplate(_rightContainer, Right);
                SetTranslate(-_rightContainer.Bounds.Width);

                break;
            case SwipeState.LeftVisible:
                _leftContainer.IsVisible = true;
                MaterializeDataTemplate(_leftContainer, Left);
                SetTranslate(_leftContainer.Bounds.Width);

                break;
            case SwipeState.Hidden:
            default:
                SetTranslate(0);
                break;
        }
    }
