[英]Navigate back & reload page
I have a problem with the navigation in my ASP.NET (Framework 4) web project.我的 ASP.NET(框架 4)web 项目中的导航有问题。 I have a login field on the master-page.我在母版页上有一个登录字段。 The master-page contains also one ContentPlaceHolder which dynamically includes other aspx pages.母版页还包含一个动态包含其他 aspx 页面的 ContentPlaceHolder。 I start on page "a" and navigate to page "b".我从“a”页开始并导航到“b”页。 When I log in on page "b", an additional node in my navigation becomes visible.当我在页面“b”上登录时,我的导航中的一个附加节点变得可见。 Now to my problem: When I push the "history-back"-button from the browser the additional node disappears on page "a".现在我的问题是:当我从浏览器中按下“历史记录”按钮时,附加节点会在“a”页面上消失。
I found out that the page "a" doesn't reload again because it's loaded from the browser's cache.我发现页面“a”不会再次重新加载,因为它是从浏览器的缓存中加载的。
I tried something with a LinkButton (Zurueck):我用 LinkButton (Zurueck) 尝试了一些东西:
protected void Page_Load(object sender, EventArgs e)
{
Zurueck.Attributes.Add("onClick", "javascript:history.back(); return false;");
}
I also tried something with cache restrictions in the C# source and in aspx source:我还在 C# 源和 aspx 源中尝试了一些缓存限制:
protected void Page_Load(object sender, EventArgs e)
{
Response.Cache.SetCacheability(HttpCacheability.NoCache);
if (Session["sessionKuerzel"] != null)
{
view = (TreeView)this.FindControl("TreeViewVerwaltung");
view.Visible = true;
login = (Button)this.FindControl("Senden");
login.Visible = false;
logout = (Button)this.FindControl("Logout");
logout.Visible = true;
benutzerrecht = (string)(Session["sessionRecht"]);
if (benutzerrecht.Equals("Administrator")){
view.Nodes[0].ChildNodes[1].SelectAction = TreeNodeSelectAction.Select;
}
else{
view.Nodes[0].ChildNodes[1].SelectAction = TreeNodeSelectAction.None;
}
view.Visible = true;
}
}
Site.Master.aspx (Head): Site.Master.aspx(头):
<meta http-equiv="cache-control" content="no-cache"/>
<meta http-equiv="expires" content="0"/>
But all these alternatives don't work with Mozilla FireFox.但是所有这些替代方案都不适用于 Mozilla FireFox。
How can I navigate back in history & reload the page again?如何返回历史记录并重新加载页面? Any ideas or solutions?有什么想法或解决方案吗?
try this尝试这个
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Response.Buffer = true;
Response.CacheControl = "no-cache";
Response.AddHeader("Pragma", "no-cache");
Response.Expires = -1441;
}
}
