View 6 RepliesI am trying to implement Login/Logout functionality in my website without using inbuilt functionality of Login controls in ASP.NET. In some pages, which require the user to be logged in, I have written this in Page_Load
if (Session["cod"] == null && Session["admin"] == null)
{
Response.Redirect("You need to Login.aspx");
}
if (Session["cod"] != null || Session["admin"] != null)
{
LinkButton1.Text = "Logout";
}
if (Page.IsPostBack == false)
{
log_bind();
grid1_bind();
grid2_bind();
}
But while I was testing this, I noticed that when I press the Back/Forward button on the browser, these pages are viewable without being logged in. How do I prevent this?
Every time I refresh the browser, my button's event handler fires again. How do you prevent this?

View 1 RepliesSuppose there is button on which there is event for adding the total sum(there is coloumn Amount in gridview) and posting the data in gridview i.e update of gridview.

View 1 RepliesI have an ASP.NET/C# application that exports some data into an Excel spreadsheet using COM interop at the click of a Button control. When I click the button, Excel is opened with the generated spreadsheet. For what it's worth, here is the button code:
<asp:Button ID="export" Text="Export to spreadsheet" runat="server" OnClick="Export_Workbook" />
This works fine, except when I click the button, close the subsequent spreadsheet, and refresh the page. When the page is refreshed after clicking the button, the call to Export_Workbook() is made again and so the spreadsheet opens again. Firefox, for example, says this when you refresh: "To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier." This is something I want to avoid.
I'm sure there's a better way to accomplish what I'm trying to do, I'm just not sure what the best approach is.
Edit
I've accomplished this by doing the following:
protected void Export_Workbook(object sender, EventArgs e)
{
Response.Redirect(Request.Url.AbsolutePath, false);
ItemList.Prepare_Workbook();
}
I have a page in which I am not using cache by using this code:
HttpContext.Current.Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1));
HttpContext.Current.Response.Cache.SetValidUntilExpires(false);
HttpContext.Current.Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
HttpContext.Current.Response.Cache.SetNoStore();
Now I want to know: Is there any difference between coming to this page using a proper link or coming back using browser back button, or is there any way to detect this?
