c# Winform 只有年份和月份 的时间控件

有没有这种控件，类似DateTimePacker 的 但是只能选择年份和月份，不显示具体是哪天的，有什么好的解决办法 告诉我啊。
谢谢啊 ，解决的 +50分

Answer 1

没有现成的，用自定义控件，界面按照下面布置就可以了，没时间作，只画了一下界面，

ExtControls.ExtButton();

是自己继承按钮控件扩展的，你用普通按钮替换下，看看效果，点击下拉按钮让plBottom可见，

注意处理下微妙控制，

月份的修改参照DateTimePicker,为lblRight添加右键菜单就可以了

Answer 2

DateTimePacker 可以让它只显示年月，但是下拉还是有日。
你说的这种情况，没有现成的控件。你可以自己写一下，这个应该不难啊

Answer 3

用2个下拉菜单控件combox好像是这个，提前把年和月添加进去就行了

Answer 4

可以直接用DateTimePicker控件
CustomFormat 属性设置为 yyyy-MM
Format 设置为Custom
