Kõik nagu õieti tehtud
<asp:scriptmanager id="ScriptManager1" runat="server" enablehistory="true" enablesecurehistorystate="true" >
</asp:scriptmanager>
aga IE8 peal hakkab kisama selliseid vigu, kollane hüüumärk all vasaskus servas
Sys.InvalidOperationException: For the history feature to work in IE, the page must have an iFrame element with id '__historyFrame' pointed to a page that gets its title from the 'title' query string parameter and calls Sys.Application._onIFrameLoad() on the parent window. This can be done by setting EnableHistory to true on ScriptManager
Vea põhjus seekord see , et ASPX lehel DOCTYPE määrab lehele HTML 4.01 direktiivi
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
aga vaja läheb XHTML
<!DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
