winform按钮和子按钮

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; } }
