在 .aspx 文件的 @ Page 指令中将 SmartNavigation 属性设置为 true

[dongchuanlu]

在需要的地方加一个书签<a name="bookmark1">

进入该页aaa.aspx#bookmark1
这样可以直接到你需要的地方

Private Sub RetainScrollPosition()

Dim saveScrollPosition As New StringBuilder
Dim setScrollPosition As New StringBuilder

RegisterHiddenField("__SCROLLPOS", "0")

saveScrollPosition.Append("<script language='javascript'>")
saveScrollPosition.Append("function saveScrollPosition() {")
saveScrollPosition.Append(" document.forms[0].__SCROLLPOS.value = thebody.scrollTop;")
saveScrollPosition.Append("}")
saveScrollPosition.Append("thebody.onscroll=saveScrollPosition;")
saveScrollPosition.Append("</script>")

RegisterStartupScript("saveScroll", saveScrollPosition.ToString())

If (Page.IsPostBack = True) Then

setScrollPosition.Append("<script language='javascript'>")

RetainScrollPosition()

回：mynewpc(水中日月)
如果我把SmartNavigation 属性设置为 true，我的关闭窗体语句将无法运行：
Response.Write("<script type=text/javascript>close();</script>");

将怎么办呢？

VB俺不懂，各位同仁最好用C#代码,谢谢..........

且IE窗体字体无故变大，这是什么回事？

复：yewei4u(yewei)
我把你的VB代码转成C# 代码应该是：

string saveScrollPosition,setScrollPosition;
RegisterHiddenField("__SCROLLPOS", "0");

saveScrollPosition="<script language='javascript'>";
saveScrollPosition+="function saveScrollPosition() {";
saveScrollPosition+=" document.forms[0].__SCROLLPOS.value = hebody.scrollTop;";
saveScrollPosition+="}";
saveScrollPosition+="thebody.onscroll=saveScrollPosition;";
saveScrollPosition+="</script>";

RegisterStartupScript("saveScroll", saveScrollPosition.ToString());

if (Page.IsPostBack)
{
setScrollPosition="<script language='javascript'>";
setScrollPosition+="function setScrollPosition() {";
setScrollPosition+=" thebody.scrollTop =' & Request('__SCROLLPOS') & ';";
setScrollPosition+="}";
setScrollPosition+="thebody.onload=setScrollPosition;";
setScrollPosition+="</script>";
RegisterStartupScript("setScroll", setScrollPosition.ToString());
}
编译通过，但执行时有错，不知那有错，请yewei4u(yewei) 及各位高手再帮帮忙吧

[XXSingle]

再经改进，把string saveScrollPosition,setScrollPosition;
改成：
System.Text.StringBuilder saveScrollPosition=new System.Text.StringBuilder();
System.Text.StringBuilder setScrollPosition=new System.Text.StringBuilder();

改setScrollPosition= 或 setScrollPosition+=
改成
setScrollPosition.Append();
就与yewei4u(yewei) 的代码相符了，但还是出错，估计javascript那出错呢？

问题还没解决，还请各位高手相助啊.................

[elfzzf]

如果你将 SmartNavigation 属性设置为 true
你不能写 Response.Write("<script type=text/javascript>close();</script>"); 语句
改成
Dim scriptString As String = "<script language='javascript'>window.close();</script>"
If (Not IsClientScriptBlockRegistered("clientScript")) Then
RegisterClientScriptBlock("clientScript", scriptString)
End If

[XXSingle]

非常感激楼上各位高手，程序功能已经实现，将 SmartNavigation 属性设置为 true
时，却产生了一个新问题：
程序设计时字体是：宋9,当IE窗体刷新时，字体无故变大（估计宋11）
字体不变时，IE布局也能看到有所改变，这是什么回事啊？

如果分数不够，还可加分...........!!!!

[SuperMark]

如果你用了样式表或重设了样式，用SmartNavigation页面PostBack后这些样式将无效，所以字体会变化。
一个简单的解决办法是将以前样式表的内容放到Head中

[yewei4u]

to XXSingle(水连天):
private void RetainScrollPosition()
{
StringBuilder saveScrollPosition=new StringBuilder ();
StringBuilder setScrollPosition=new StringBuilder ();

RegisterHiddenField("__SCROLLPOS", "0");

saveScrollPosition.Append("<script language='javascript'>");
saveScrollPosition.Append("function saveScrollPosition() {");
saveScrollPosition.Append(" document.forms[0].__SCROLLPOS.value = thebody.scrollTop;");
saveScrollPosition.Append("}");
saveScrollPosition.Append("thebody.onscroll=saveScrollPosition;");
saveScrollPosition.Append("</script>");

RegisterStartupScript("saveScroll", saveScrollPosition.ToString());

if (Page.IsPostBack)
{
setScrollPosition.Append("<script language='javascript'>");
setScrollPosition.Append("function setScrollPosition() {");
setScrollPosition.Append(" thebody.scrollTop = " + Request["__SCROLLPOS"] + ";");
setScrollPosition.Append("}");
setScrollPosition.Append("thebody.onload=setScrollPosition;");
setScrollPosition.Append("</script>");

RegisterStartupScript("setScroll", setScrollPosition.ToString());
}
}

private void Page_Load(object sender, System.EventArgs e)
{
RetainScrollPosition();
}

偶就是这样用的，能够实现的！
