Change the UpdatePanel.UpdateMode to Conditional.
将UpdatePanel.UpdateMode更改为Conditional。
The content of the UpdatePanel control is updated under the following conditions: If the Update method of the UpdatePanel control is called explicitly.
UpdatePanel控件的内容在以下条件下更新：如果显式调用UpdatePanel控件的Update方法。
If a control is defined as a trigger by using the Triggers property of the UpdatePanel control and causes a postback. In this scenario, the control is an explicit trigger for updating the panel content. The trigger control can be either inside or outside the UpdatePanel control that defines the trigger.
如果通过使用UpdatePanel控件的Triggers属性将控件定义为触发器并导致回发。在此方案中，控件是更新面板内容的显式触发器。触发器控件可以位于定义触发器的UpdatePanel控件的内部或外部。
If the ChildrenAsTriggers property is set to true and a child control of the UpdatePanel control causes a postback. In this scenario, child controls of the UpdatePanel control are implicit triggers for updating the panel. Child controls of nested UpdatePanel controls do not cause the outer UpdatePanel control to be updated unless they are explicitly defined as triggers.
如果ChildrenAsTriggers属性设置为true并且UpdatePanel控件的子控件导致回发。在这种情况下，UpdatePanel控件的子控件是用于更新面板的隐式触发器。嵌套UpdatePanel控件的子控件不会导致更新外部UpdatePanel控件，除非它们被明确定义为触发器。
