How to Insert Radio button which is clicked in the form in a Message Box which has other information along with the Radio buttons in Visual Basics?

Question

I am trying to display message box which has labels, text box and listbox and radio button. In my message box whatever information i choose in the form I should get that information in Message box. I could get all the information except the Radio buttons. Please anyone tell me how to write a code for inserting a radio button clicked information in the same message box which has other information too.

Public Class Form1
    Const Pizza_Price As Double = 2.99
    Const Fries_Price As Double = 1.99
    Const Drinks_Price As Double = 0.99

    Private Sub Btn1_Click(sender As Object, e As EventArgs) Handles Btn1.Click
        Dim Total As Double




        If IsNumeric(txtPizza.Text) And IsNumeric(txtFries.Text) And IsNumeric(txtDrinks.Text) Then
            Total = Calculate()
            DisplayBill(Total)

        Else



            MsgBox("Incorrect data Entered")

        End If

    End Sub

    Public Function Calculate() As Double

        Dim Total As Double
        Dim pizza_quantity As Integer = txtPizza.Text
        Dim fries_quantity As Integer = txtFries.Text
        Dim drinks_quantity As Integer = txtDrinks.Text

        Total = (Pizza_Price * pizza_quantity) + (Fries_Price * fries_quantity) + (Drinks_Price * drinks_quantity)

        Return Total

    End Function

    Public Sub DisplayBill(Total As Double)

        ListboxDisplay.Items.Add("Item            Price           Quantity")
        ListboxDisplay.Items.Add("Pizza            " + FormatCurrency(Pizza_Price, 2) + "               " + txtPizza.Text + "                   ")
        ListboxDisplay.Items.Add("Fries             " + FormatCurrency(Fries_Price, 2) + "               " + txtFries.Text + "                 ")
        ListboxDisplay.Items.Add("Drinks          " + FormatCurrency(Drinks_Price, 2) + "               " + txtDrinks.Text + "                  ")
        ListboxDisplay.Items.Add("                                                                                    ")
        ListboxDisplay.Items.Add("Total Sales                    " + FormatCurrency(Total, 2))
        LBox.Items.Add("Total Sales:    " + FormatCurrency(Total, 2))
