Answer 3

On the form where you have the ComboBox on the click of Submit Button you can do something like this

Letz say your Page1 is ExtCourse than

ExtCourse.CourseName = ComboBoxCourse.GetItemText(this.ComboBoxCourse.SelectedItem);

and on ExtCourse.cs

public string CourseName { get; set; }

than you can assign

TextBoxCourseName.Text = CourseName;
