No
is the page containing the logout button a secured page
If so, that scenario will not happen
foreach(Minute m in MyLife)

The main page contains the top menu links in which Logout is one of thelink
for example if a user does some transaction in the main page and later clicks the logout link, he will be directed to the logout.aspx page..
but when he click back button the main page is visible..
even though I had added filter that if the session is valid then only page gets visible...
I had just now checked in this site that when i try to click back button it assked me a confirmation when I clicked "CANCEL" it remains in same page If clicked "OK" it directs to previous page...
how can we do this...

When you use Response.Expires propery, the browser will be expired in a given time.
Then previous page is expired when user hits back button.

Where are you getting this error?
What about these Two :
OnPageIndexChanging="grdView_PageIndexChanging"
and
protected void grdView_PageIndexChanging(Object sender, GridViewPageEventArgs e)
{
grdView.PageIndex = e.NewPageIndex;
grdView.DataSource = bindgrid();
grdView.DataBind();
}

we can do this.. Infact just now I saw the similar one in this forum only...
when I try to reply one of the post...
try by clicking the reply link and enter some text in the space provided and click back button...
you can see the effect which you are looking for...

You can attempt this in two ways
1) Disable the back button (plenty of examples for that) and handle the backward navigation from controls on your page.
2) Handle the onUnload event in JavaScript and determine if it came from the back button
only two letters away from being an asset

can you send me a link please from one of those plenty examples. I tried many of them, but nothing is really happening on that specific file, the back button is still enabled.
thanks, Laziale

Fact is, you cannot reliably turn off the back button. You're better off just fixing your code so that the back button doesn't do anything you don't want it to, such as log people back in.

I have a usercontrol which is to open a new window. This seems simple enough, but my code just does not work - clicking on the link button has no effect.
Here is my .ascx file:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="TextContainer.ascx.cs" Inherits="SolutionsUI.Controls.TextContainer" %>
<asp:UpdatePanel runat="server" ChildrenAsTriggers="true" >
<ContentTemplate>
<div class="rbroundbox">
<div class="rbtop"><div>
</div></div>
<div class="rbcontent">
<asp:Label ID="lblContent" runat="server" Text="PlaceHolderText">
</asp:Label>
<div id="divEdit" runat="server" style="vertical-align:text-bottom; text-align:right;">
<asp:LinkButton ID="btnEdit" runat="server" Text="Edit" style="font" Font-Size="10pt" Font-Underline="True" Visible="true" ForeColor="White" OnClick="btnEdit_Click">
</asp:LinkButton>
</div>
</div><!-- /rbcontent -->
<div class="rbbot"><div></div></div>
</div><!-- /rbroundbox -->
</ContentTemplate>
</asp:UpdatePanel>
It is my understanding that you are not to use Response.Write for javascript when using Ajax. Instead, I register the script in my code behind function (which I have been able to step through).
protected void btnEdit_Click(object sender, EventArgs e)
{
Session["PageID"] = "1";
Session["PanelID"] = "1";
StringBuilder OpenScript = new StringBuilder();
OpenScript.Append("window.open('PopUpEdit.aspx");
OpenScript.Append("?pageid=");
OpenScript.Append(Session["PageID"]);
OpenScript.Append("'");
OpenScript.Append(",'Edit','width=400, height=450')");
OpenScript.Append("PopUpEdit.aspx");
OpenScript.Append("?pageid=");
OpenScript.Append(Session["PageID"]);
OpenScript.Append("'");
OpenScript.Append(",'Edit','width=400, height=450')");
string url;
url = OpenScript.ToString();
Page.ClientScript.RegisterStartupScript((this.GetType()), "OpenWin", "<script>openNewWin('" + url + "'</script>");
This did not work, nor did an alert:
Page.ClientScript.RegisterStartupScript(this.GetType(), "alert", "alert('" + "Test" + "');",true);
}
There is no javascript error or anything...it just does not launch the window. I see the following in the status bar:
javascript:__doPostBack('TextContainerIntro$btnEdit','')
Can anyone tell me how to do this?

Hello world!
Can’t anyone help me with this problem.
When the user click a button I store some information in to a session cookie on the server (hope that is the correct terminology) When the page reloads and I try and recover the information from the session state cookie it tells me that the object does not exist.
“Object reference not set to an instance of an object.”
Thanks for you help

In which line you are getting the error ? Did you check the session value is null or not ?
