AsyncPostBackTrigger&之间有什么区别? PostBackTrigger?

What is the difference between AsyncPostBackTrigger & PostBackTrigger?

推荐答案

默认情况下，UpdatePanel中的控件会导致部分页面更新，外部控件会导致回发，使用这些触发器可以根据需要更改此行为.

Controls inside an UpdatePanel by default cause a partial page update, controls outside cause a postback, using these triggers it is possible to change this behaviour as required.

AsyncPostBackTrigger

• 将回传转换为异步回叫*通常用于 当UpdatePanel外部的控件回发时触发更新*如果 ChildrenAsTriggers ="false"，可用于指定哪些控件 UpdatePanel内部应该回叫而不是回发

AsyncPostBackTrigger

• Converts postbacks into async callbacks * Typically used to trigger updates when controls outside an UpdatePanel post back * If ChildrenAsTriggers="false", can be used to specify which controls inside UpdatePanel should call back rather than post back

• 让UpdatePanel内部的控件回发. *通常用于 当ChildrenAsTriggers ="true"
时，允许某些控件回发

• Lets controls inside UpdatePanel post back. * Typically used to allow certain controls to post back when ChildrenAsTriggers="true"
