I have an ASP.NET problem. When I press Back on Internet explorer, the previous page will be appeared. I need to prevent this page form appearing. How can I do this
View 3 RepliesI'm currently building a simple chat application and I have everything working real smooth except for one thing, and this problem is only in IE as far as I know (in firefox there is no problem).
In my chat application I have the textbox where the user writes the messages to the chat and the button that sends this message togheter in an updatepanel (so that there is no visible postback when pressing the button). I also have in the form tag "defaultbutton=" set to the button. The problem is that when the user uses Internet explorer and presses Enter instead of pressing the button with the mouse that after the 2 first times he/she does this causes the textbox to stop focus on it, which it shouldnt do as in the end of the button the code says it should focus, which works the 2 first times for some reason.heres the code where the problem exists:
aspx:
form id="form1" runat="server" defaultbutton="Button1">
<asp:ScriptManager ID="scriptManager" runat="server">
</asp:ScriptManager> [code].....
how can i get around the following problem-i have a drop down list control on one of my pages- ddlEmployeeTypeit lists 1.Perminent2. Contract3.Tempon selected index change, if its contract or temp, then a text box appears where the user need to type in the contract expiry date-so changing from Perminent --> Contract text box appears- but when the internet explorer back button is clicked - the text box dissapears (which is fine) but the ddl does not change it still reads contract i wanted it to revert back to perminent.is there a solution to this problem?
View 4 RepliesI have developed some aspx pages using visual studio 2008. I am authenticating using Active Directory services. I have kept a link button on my aspx page which says signout .What exactly i want to do is that i want the back button of my login page to be disabled so that when i press signout and when my login page loads users cant go back and thus forced to enter the login details. I am using c# as development language.
View 7 RepliesI've got an asp.net page that uses dynamically populated DropDownLists and OnSelectedIndexChanged events. A few days ago I found a defect where hitting the back button would load the previous page from the browser's cache, so the DropDownList would already have a selected index (hence the OnSelectedIndexChanged event would not fire properly as it didn't have the default selected index). I understood the issue and googled around. It's a well known issue that doesn't have an easy solution because of how the browser interacts with the page. After a bit of thought, I went with a trivial javascript solution to reset the ddls:
var gvTable = document.getElementById("foo");
if (gvTable != null)
{
[code]...
This worked well and I was happy. Until I tested it in IE. In IE, it appears to run the script, THEN load the cached values of the DDL. That is, I observe the DDL snapping back to the 0 index, and then suddenly dropping down to the previously selected value. I'm sort of at a loss here, I typically debug in firebug, but this works perfectly in firefox and chrome.
In an ASP.NET 3.5 website we are noticing that the back button is not working properly. If the user does several postbacks (say 10 times), and than starts pressing back button - the back button gets disabled before the user gets through all the pages. The site does not use AJAX.net.
I can reproduce the issue on IE 7 and 8 almost always. The problem seems to be with some sort of limit IE has on History Cache for a given tab/instance. In the tests I did the post request to the server are large - around 83k, and the responses are are round 300k. It seems that with these request sizes the history does not hold more than 4 items. The moment I get to the 5 post, the first item i had selected is dropped.
I'm using a wizard control with 4 steps, when I use the previous button to navigate back to the previous step the page reloads but at the bottom of the page.Instead of showning the whole of the page, the user views the footer of the site and the previous button and next button.I'm sure there is a very simple answer to this but I just can't figure out how to get the page to reload to the top.
View 8 RepliesI am developing a web application in ASP.NET3.5 with C#. I also using Telerik RadAjax Control. When user click the menu then open the page with a new tab(Like web Browser).I want to create, when user back any previous tab(page) the will be show the previous data without loading 2nd time( like browser tab). Is it Possible ?
View 2 RepliesI am having problem while using onclick="javascript:history.back();" with Aspnet. In the first page i filled some data and click search button it show some results, i click on particular result for its details which navigate to the 2nd page but when i click on custom back button it refresh the page and all data set to initial values,when i use onclick="javascript:history.back();" I get nothing but the page displays "webpage has expired."
View 1 RepliesAlright, I am completely baffled by this one. When filling out this page in IE8, it will SOMETIMES clear all entered data (including radio choices) when you select Yes, No, or Not sure (line 892 in the code). This is a postback question, as it should potentially show more questions. This problem does not happen in any other browser, and rarely in IE8. I have no idea what is causing it, the code I am using has been used in similar applications and I can't find any change which results in this behavior.
The full code can be found here: http://pastebin.com/a12cPzyF
I am using an image button and on click of it i want to go to visited page.
Now i am using - Response.Redirect(Request.UrlReferrer.ToString()),
It is going to previous page, but when i am in a page of some user details where the link is looks like - users.aspx?userid=25 and i visit some other page and click back(image button) i want to see the same serdetail page. How to track that.
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?
when i test this page http://www.catalogues4u.com.au/ViewCategory.aspx?catID=119 im getting the above error. to replicate this issue visit the above page in ie7 and you will get the prompt.
View 3 RepliesI'm trying to publish my page and received this error when open it:
[Code]....
When I browse it in the development environment using Microsoft Web Developer 2005 it view just fine. I then copy all my files & put in C:Inetpubwwwroot and open IE to view it, the above error showed up. In IE8|Tools|Internet Options|Advance, I uncheck "Show Friendly Http Error Msgs" in hoping that it'll show me something more than the basic error, but I'm not getting much more.
Can I disable all properties of an Internet Explorer when it opens a particular page called "help.aspx".I want that no option should be displayed on that page,just the content of the page which include the image of a person.

I 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?

I'll try to specify my problem as simple as possible! I have a problem comunicating between 2 pages; Products.aspx and ProductDetail.aspx. On Products.aspx i have about 15 DDL's on the left side (all set to autopostback), and 1 ListView ond the right side. Results in my ListView control are based on selcted items from DLL's on the left. Every single result in Products.aspx has a dynamical hyperlink to the ProductDetail.aspx. Now when I click on specific product in ListView I'm redirected to ProductDetail.aspx page, and everything works fine! If I click on the Back button in IE or FF it works also fine because it returns me to the previous Products.aspx page and all my results based on selected items in DDL's are still there!
The problem comes when causing some more autopostback's in ProductDetail.aspx page, because every autopostback is counted as a new page request and therefore i have to click Back button in IE or FF for more then 1 time to come back to the previous Products.aspx page.
I tried to implement code BELOW in ProductDetail.aspx.vb but it does not completly fulfill my expectations, becase all my searching criteria are lost when returned to the previous page (Products.aspx)
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
ViewState("ReferrerUrl") = Request.UrlReferrer.ToString
End If
End Sub
Protected Sub BACK_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles BACK.Click
Response.Redirect(ViewState("ReferrerUrl").ToString)
End Sub
Does anybody knows any other solution how to come Back to previous page with only ONE CLICK without loosing searching criteria?
when press back button the previous page control value erased..but I want the control value should be visible.
View 4 RepliesConsidering three webpages. In all pages there are gridivews. The gridview columns has numeric data.
When user click on data figure suppose 29 then it redirects to other page with 29 records. In the redirected page if user again click on data suppose 12 then it redirects to another page with 12 records.
I want to give option to user that if form third page he wants to go back by clicking a hyperlink on that page then the second should appear in its previous state i.e. have showing the clicked value 29 and if he wants to go the first page then first page should keep and display its previous state with the searched data.
