您可以使用计时器控制并指定显示模态窗口的毫秒间隔

You can use timer control and specify the interval in milli seconds for displaying modal window

使用计时器控件。在Timer控件的tick事件中调用javascript函数并显示警告。



设置Timer控件属性的时间。

use a timer control. In tick event of the Timer Control call the javascript function and show the alert.

Set the time in Timer control property.
