UserControl and setting text

[Lethal]

The usercontrol will need to expose properties. For example:

public string TextBoxContents {
    get {
        return txtName.Text;
    }
    set {
        txtName.Text = value;
    }
}

Remember, a usercontrol is like a black box, it's internal data is hidden from the outside (concept of encapsulation). Only expose what needs to be exposed.
