As FindControl is not recursive, you have to replace this code :

Label FeedbackLabel = (Label)FindControl("FeedbackLabel");
TextBox InputTextBox = (TextBox)FindControl("InputTextBox");

by this code :

Label FeedbackLabel = (Label)Panel1.FindControl("FeedbackLabel");
TextBox InputTextBox = (TextBox)Panel1.FindControl("InputTextBox");

However, according other answers, you should move the declaration (not the instantiation) outside the method (at class level) in order to easily get an entry for your controls.
