You can add a property that holds the inner UserControl.

Accessing a control in another form is bad practice. If you insist on doing so, simply make the control public (by default, it's either protected or private).

Also, controls INSIDE the user control are also not public, so you may need to change their access level as well.

There are many other more correct ways to get to the data/properties of another form's control, one of which being a global static class that is manipulated by other objects (namely, forms) that set/get properties within that class, or an object internal to the form that contains the controls you want access to that exposes those controls' values.
