To maintain the scroll position for the large web page you can use on of these methods :
要保持大网页的滚动位置，您可以使用以下方法之一：
1- use Web.config page section <pages maintainScrollPositionOnPostBack="true" />
1-使用Web.config页面部分 <pages maintainScrollPositionOnPostBack="true" />
: this will maintains the scroll positions for all the web site pages.
：这将保持所有网站页面的滚动位置。
2- in the page declaration <%@ Page MaintainScrollPositionOnPostback="true" %>: this will maintains the scroll position for this page only.
2- 在页面声明中 <%@ Page MaintainScrollPositionOnPostback="true" %>：这将仅保持该页面的滚动位置。
3- programmatically from code behind System.Web.UI.Page.MaintainScrollPositionOnPostBack = true;: this will maintains the scroll position for this page only (the same as page declration).
3- 从后面的代码中以编程方式System.Web.UI.Page.MaintainScrollPositionOnPostBack = true;：这将仅维护此页面的滚动位置（与页面声明相同）。

You could register the a javascript to move the scroll to the position of some control that you want, like this:
您可以注册一个 javascript 以将滚动条移动到您想要的某个控件的位置，如下所示：
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack)
{
RegisterStartupScript("ScrollScript", "document.getElementById('objectId').scrollIntoView(true);");
}
}
Changing the objectId in the script for the Id of the object you want to scroll to.
将脚本中的 objectId 更改为要滚动到的对象的 Id。
As noted by Guy Starbuk in the comments, RegisterStartupScriptis deprecated in .Net 4 and now the recommended way to register a script is:
正如 Guy Starbuk 在评论中所指出的，RegisterStartupScript在 .Net 4 中已被弃用，现在推荐的注册脚本的方法是：
ClientScript.RegisterStartupScript(GetType(), "ScrollScript", "document.getElementById('objectId').scrollIntoVie??w(true)", true);

In asp.net web pages you can add an OnClientClick event to the control causing the server post back to scroll the page to the bottom.
在 asp.net 网页中，您可以向控件添加 OnClientClick 事件，从而导致服务器回发将页面滚动到底部。
<asp:Button ID="MyButton" runat="server" Text="Submit" OnClick="MyButton_Click" OnClientClick="window.scrollTo(0, document.body.scrollHeight);" />

Create an anchor on the page, then on onload:
在页面上创建一个锚点，然后在 onload 上：
window.location.href = "#myanchor"

One thing missing from the answers here is a delay. It's all well and good if there is no change in the height of the web page during load. But if there are a lot of images and your trying scroll past them; they can bump your view back up again.
这里的答案中缺少的一件事是延迟。如果在加载过程中网页的高度没有变化，那一切都很好。但是如果有很多图像并且您尝试滚动它们；他们可以再次让您的视野恢复原状。
What is needed is a window.onload function call:
需要的是 window.onload 函数调用：
ClientScript.RegisterStartupScript(GetType(), "ScrollScript", "window.onload = function() {document.getElementById('objectid').scrollIntoView(true);}", true);
