关于ComboBox的时间控件问题

[FEIHUKT]

三个combobox控件
第一个先择年
第二个选择月
第三个选择日
引用别人的
"
combobox1.Items.Add("2009");
combobox1.Items.Add("2008");
combobox1.Items.Add("2007");
combobox1.Items.Add("2006");
combobox1.Items.Add("2005");
combobox1.Items.Add("2004");
combobox1.Items.Add("2003");

也可以写个循环 "
问题：
1.用for循环来怎么写?
2.代码写在哪里。写在combobox的change事件里吗?
3.要三个combobox关联.怎么写?
4.要考虑润年润月的情况
4.写出来的时候。我要在datagridview里显示自己所选择的日期怎么写?
