winform按钮和子按钮

实现目标:

两组按钮1和2,其中按钮2有两个子按钮,

(1)当选按钮1时,按钮2和其子按钮不选中;

(2)选中按钮2或其子按钮3和4时,1不选中

(3)选中按钮2时,默认选中其子按钮3

(4)选中2的子按钮3或4时,默认选中2

 

如图所示,需要注意的是,要将2的子按钮3和4放在一个panel里

按钮的事件代码:

    private void radioButton1_CheckedChanged(object sender, EventArgs e)
        {
            if (radioButton1.Checked)
            {
                radioButton3.Checked = false;
                radioButton4.Checked = false;
            }
        }
        private void radioButton2_CheckedChanged(object sender, EventArgs e)
        {
            if(radioButton2.Checked )
            {
                if (!radioButton4.Checked)
                {
                    radioButton3.Checked = true;
                }
            }
            
        }

        private void radioButton3_CheckedChanged(object sender, EventArgs e)
        {
            if (radioButton3.Checked)
            {
                radioButton1.Checked = false;
                radioButton2.Checked = true;
            }
        }

        

        private void radioButton4_CheckedChanged(object sender, EventArgs e)
        {
            if (radioButton4.Checked)
            {
                radioButton1.Checked = false;
                radioButton2.Checked = true;
