Problem with Radio Button and Form Navigation
I have a set of radio buttons on a Windows Form. A click of a button is supposed to open a Windows Form.
The appropriate form opens when the button is clicked. However, the first click of a button, each click opens the form it's supposed to open plus the previous form that was opened.
For example, if I click the first button, Form A opens. I close Form A, and then I click the second button. The second button is only supposed to open Form B, but it opens Form B AND Form A when it is clicked.
Here is the code:
using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
namespace DBInfo
{
///
/// Summary description for Form1.
///
