I have a page, the user types in e-mail and then submits. The next page is a confirmed page - letting the user know that his -mail was entered. If you then click back, the forum will try to re-submit itself. Is there a way to stop this?

I am running one application where one gridview is there when i am deleting any data there it shows one message for deleting.
for message i used this code:
ClientScript.RegisterStartupScript(this.GetType(), "ShowMessage", string.Format("<script type='text/javascript'>alert('{0}')</script>", "this row is deleted"));
after that i am going to some other page ,after going other page when i click on back button in browser it is coming in the previous page but the message which poped up before again getting popup.
In my app, there is a grid that you can drill down. You can go back to prev view via some links but the back bowser button is not integrated to that, so that if you do hit the back browser button, it logs out of the app which I don't want. I would be happy if it would redirect to the first page. I think this part is what we need. [URL] this is the startpage.xaml, at the end there is the hyperlink - so maybe here I can see if the back browser is pressed ( there is no other place in the codes that would navigate out), and if this is pressed I can redirect to a different spot? Is this a sound idea and how do I check if this back browser has been pressed?

I am developing a simple rating system for my employer's profile based web-app. Here is my problem:
The actual page is domain.com/review.aspx?user=username, but I use the url-rewrite module in IIS to use domain.com/username/review The page contains a repeater control that displays reviews for that username, as well as a form for people to create new reviewsWhen the form is submitted, asp.net re-appends the (hidden) querystring to the url on postback.The post-back url is now domian.com/username/review?user=username&review, causing the page to break if refreshed.
Is there any way to keep asp.net from re-appending the querystrings that are actually already present, but re-written with IIS
Live link <- submit a review, and then refresh the page (edit) by clicking in the address bar! Beautiful yellow error message.
EDIT
C# code:
protected void submitReview(object sender, EventArgs e)
{
try
{
int starRating = txtStarRating.Text == "" ? 0 : Int32.Parse(txtStarRating.Text);
testimonials.addNew(Int32.Parse(txtHiddenUid.Text), reviewContent.Text, reviewerName.Text, true, starRating);
[Code]....

View 1 RepliesI've got a form that when a button is clicked it sends the data to a database and returns a record number. how can i stop the user form using the back button and hitting enter again?

2. once the user has gone to the next page, he should not be able to come back to previuos page,; if at all he comes back-- all the form fields should get cleared. how?
I have a .aspx page that can be called from two other pages in the same project. There is a "Back" button on that page. When the user clicks on the back button, how do I know to which page (called from page 1 or page 2) I should go back?
View 8 RepliesI need to stop users users using the browser back button and potentially submitting an old version of a form.
I'm storing a guid in a session variable and also writing the value to a hidden form field and then checking the session value against the hidden field value if a user does try to navigate back and submit an old form.
If the form is submitted and the user wants to complete a new copy of the form then a new guid is generated both to the session and to the hidden form field. Now, if the user decides to hit the back button a few times to get the old form and tries to submit it again, the page checks the current guid in session against the guid stored in the form field and it finds a mismatch and prevents the form being submitted.
This works as expected in Chrome and Firefox, but in IE6, when the user hits the back button to view the old form, the new guid value appears in the hidden field of the old form! This means the user can submit the old form again, which we definitely do not want.

I use MVC2/asp.net and try to develope something like a wizard. This wizard will have serveral websites. The user will be able to enter some information on website A and to navigate then towebsite B (by pressing a button which triggers the Http.Post event). No problem up to this point.
Also on website B can the user enter some information. But there he has two buttons: "Back" and "Forward".
How to identify here which button was pressed?

I am trying to see if it possible to create a back button that goes back 3 pages and refreshes that page. The make up of my page is a little complex. The Home page has a password prompt that enables a multiview to be visible with a gridview of information. The gridview has a details link that has a 2 querystrings that gets sent to the details page. The details page has the ability to be edited and updated. this is why I wanted it to go back 3 pages. The code I am using to go back is
<asp:Button ID="Button2" runat="server" CausesValidation="False" OnClientClick="javascript:history.go(-3);return false;" Text="Back" UseSubmitBehavior="False" />
I have an update panel on the parent page into which I load and remove a set of user controls.
Now, when a button is pressed on the user control, the events are fired but there are no changes in the page. For example:
Main Page
<updatePanelMain>
<childcontrol1>
<childcontrol2>
etc
ChildControl.ascx
<update panel 1>
<panel1/>
<panel2/>
<btn1/>
etc
So, if I want to hide panel 1 when btn1 is clicked etc, I simple use code such as panel1.visible = false.
All this gets executed but nothing happens to the page.
<asp:UpdatePanel ChildrenAsTriggers="false" UpdateMode="Conditional" ID="updatePanel"
runat="server" EnableViewState="true">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnSubmit" EventName="Click" />
</Triggers>
<ContentTemplate>
However, when I use placeholders instead of update panels in the child controls, I dont face any such problems.
<asp:PlaceHolder ID="placeholderTypeOfInvestor" runat="server">

View 6 Repliesi have a form which allows the user to key in the data and then submit.
if everything works well on this action result, then i will redirect the user back to a thank you page.
my problem right now is that when the user click on the back button, they will be able to go back to the form page and the inputs will still be there.
and if the user just click on submit again, i will be getting some potential weird bugs.
so in terms of asp.net mvc, what's the best way to handle users who click on the back button?
I'm working on a asp.net forms web application where I've got advanced search form with grid listing results below. Grid is sortable and pageable. Grid is listing products.
I've got two requirements :
1) make the url remember the advanced search form state so search results page can be bookmarked etc.
2) on the product details page there is a back button that should take the user to the advanced search page with the same settings in the form and same grid state.
I have implemented a workaround to above two problems but I don't think my solution is very clean and I'd like to hear better ideas. My workaround is as follows :
1) I iterate through form fields and I put values into the querystring after the hash. So when the page is loaded it gets the values from url if available.
2) when user clicks a link to product details page from the grid I use javascript to create a cookie with url to advanced search page so when rendering the product details page I know the url for the back button.
am creating a web application in using c# with asp.net.
in that am using login page only as normal aspx page. other pages are using masterpage.
when i click logout button in masterpage. page will redirect to login page. after that if i click browser back button it was moving to previous page. how can i prevent this.
am using this following code in master page aspx page. And My log out button code is below.
<%if (!Page.User.Identity.IsAuthenticated)
{ %>
<script type = "text/javascript" >
function preventBack() { window.history.forward(); }
setTimeout("preventBack()", 0);
window.onunload = function() { null };
</script>
<%} %>
But exactly what i need is once if login page loaded or logged out then it wont go to previous page.
I have an aspx page with many buttons and i have a search button whose event i want to be triggered when user press enter.How can i do this?
