我在一个页面中使用了3个定时器，分别是1000ms，500ms，3000ms，并有多个更新面板，但是当它运行到实时项目中时，页面自动保持上下滚动，在本地主机中运行也有同样的问题，但效果不大。有谁能解释一下原因和如何解决？
我也把
<pages smartNavigation="true" maintainScrollPositionOnPostBack="true"></pages>
在我的webconfig文件中
这是我的代码

解决
只需将此脚本添加到您的页面中
<script type="text/javascript">
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_beginRequest(beginRequest);
function beginRequest() {
prm._scrollPosition = null;
}
</script>
