Well regardless of what you will end up doing with the value when selected, it is safe to use the SelectionChangeCommittedevent.
好吧，无论您最终会使用该值做什么，都可以安全地使用该SelectionChangeCommitted事件。
Here is a little follow up info on this event vs the other commonly used events. (from MSDN)
以下是有关此事件与其他常用事件的一些后续信息。（来自 MSDN）
SelectionChangeCommitted is raised only when the user changes the combo box selection. Do not use SelectedIndexChanged or SelectedValueChanged to capture user changes, because those events are also raised when the selection changes programmatically.
SelectionChangeCommitted 仅在用户更改组合框选择时引发。不要使用SelectedIndexChanged或SelectedValuechanged来捕获用户更改，因为在编程方式更改时也会提出这些事件。

I usually use the SelectedIndexChangedevent to check when a user selects a value in a combobox
我通常使用该SelectedIndexChanged事件来检查用户何时在组合框中选择了一个值

How about if you are using the DateTimePicker? This does not have the SelectionChangeCommitted value.
如果您使用的是 DateTimePicker 呢？这没有 SelectionChangeCommitted 值。
