Nice Chap，
两种方式。
设置一个布尔开关来评估事件
或
以编程方式删除处理程序
以编程方式执行此操作（并在之后设置（返回））
我希望这会有所帮助，

Nice Chap,
Two ways.
Set a Boolean switch to evaluate that in the event
or
delete the handler when you do it programmatically
When you do it programmatically (and set it (back) afterwards)
I hope this helps,
Cor

您可能想要设置一个标志（例如，在以编程方式更改值之前设置控件的'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' />

You may want to set a flag (for example, by setting the control''s ''Tag''
property) before changing the value programmatically and check this flag in
the ''TextChanged'' event handler.
