推荐答案
您好，Seyed，
您可以通过在发生刷新"事件时执行一个简单的JavaScript来做到这一点.
Hi Seyed,
You can do this by executing a simple JavaScript on whenever the "refresh" event occurs.
<script type="text/javascript" language="javascript">
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
function EndRequestHandler(sender, args) {
var TextAreaDiv= document.getElementById("TextAreaDiv");
TextAreaDiv.scrollTop = TextAreaDiv.scrollHeight;
}
</script>
将TextAreaDiv替换为包含TextArea的Div的ID或为TextArea提供滚动功能的元素的ID.
您需要将此代码段放入< head>标签或在< body>内部.在使用UpdatePanel时，我必须假定您已在aspx页面上放置了一个脚本管理器.
希望这会有所帮助！
快乐编码:)

Replace the TextAreaDiv with the ID of Div containing TextArea or of the element providing scroll facility to TextArea.
You need to put this code snippet inside <head> tag or inside the <body>. As you''re using UpdatePanel I must assume that you have placed a Script Manager on your aspx page.
Hope this helps!
Happy Coding :)
