[解决办法]
你想干嘛？
是不是几个checkbox（复选框）只允许勾选一个？
可以改用radiobutton（单选）或者写事件来限制
[解决办法]
多选一就用radiobutton。
多选N就用checkbox。
如果是多选一或者多选0，那就要看怎么方便了，可以radiobutton加清除按钮，或者checkbox控制互斥。
如果你说没法做，那只能说明你的逻辑思维能力太差！
[解决办法]
这个不复杂啊，在CheckBox的Click事件里，如果Checked的值为true，就遍历同一个容器控件下的其它CheckBox，把它们的Checked属性设置为false就可以了啊。
checkbox1_Click(object sender, EventArgs e){ (CheckBox)cb = (CheckBox)sender; if (cb.Checked) { foreach (Control ctl in cb.GetContainerControl().Controls) { CheckBox cb1 = ctl as CheckBox; if (cb1 != null && cb1 != cb) cb1.Checked = false; } }}
