View 4 RepliesI'm writing a web-based application for internal use within the business where I work. It's a fairly complex application, with a lot of forms that will allow the user to view and enter data, which once saved will be stored in a database.
One thing I'm anxious to avoid is allowing a situation to exist where a user might enter large amounts of data in the browser, and then (either deliberately or inadvertently) navigate off the page without saving the changes. To this end, I have already implemented an entry page which opens up a new browser window in which there are no navigation controls at all; only what is provided on the web pages themselves.
However, there are two potential ways in which a user could still lose data:
The browser Close button is still enabled, and a user could potentially lose work by clicking it inadvertently. I can probably live with this, as it falls at the extreme end of helping the user not to shoot himself in the foot. In Internet Explorer (and, apparently, in Firefox) the Backspace button works like a Back button. I only discovered this accidentally, and have as yet been unable to find a simple way of stopping this behaviour. This is potentially a problem, as an inadvertent use of the Delete key (e.g. having positioned the cursor in a read-only textbox, or when the cursor isn't on any particular field in the page) will navigate off the page.
What I would like to do, as a minimum, is prevent Backspace from navigating off a page if that page has any user-writable fields on it and any of those fields have been changed by the user since the form was loaded. Ideally, I would like to disable this particular use of the Backspace key completely, while the user is logged into this web application. The two possible ways that I can think of, for achieving this, are: (1) clear the browser's history as each page is loaded, or (2) trap the Backspace key and only allow it to work if the cursor is positioned within a field whose text can be changed (e.g. a textbox).
how I could achieve either of these things? The solution needs to be programmatic, rather than something that has to be manually configured on every browser in the company.
I have a gridview that does a select statement against a sql database. What I want to do is have the data in the gridview refresh upon either hitting the back button or the forward button.
If the back button is pressed it should give me yesterdays data from the table. If I hit the forward button it should give me tomorrows data, at the same time i want the forward button to be limited to going forward only 5 days from todays date. I figure that I have to do this in a Updatepanel however I am unsure as to how to do this.
customers does not want to allow user to use back or forward button. Just a clean page without commandbar and toolbar, same for FF an IE. Disabling them is not an option as now.

View 5 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?

Not sure if i'm posting in the right forum, if not, please move it...i have the following issue... I want to "disable" browser's back button. Seems it's not possible, but using cache.setcacheability and timing it, kinda disables the option of navigating back. I need this because in some pages of my webpage, i keep values in a Session variable so when a page loads, i need to check that variable, and, if navigating back, cant do that. I also "set cache to false" because if someone closes session, and i allow cache, someone else could handtype a url in that same pc and see the page without login (though if he/she tries to navigate through it will be kicked out because when loading a new page, i'll know that he/she is not logged) but i dont want to allow even that,
that's why cache is disabled. The problem is that loading over and over again my masterpage (header, footer, menu and stuff) is going to slow down the webpage, because every time there's a request, the page has to be sent again completely. So, is there something like a "mix" mode where i can allow cache just for a few things? If not, what's the best practice to achieve both things i'm trying: speed and security?

When i use back button on browser, then I did not get session value.
How to store session on browser back button.
i 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?
My program has 4 pages that have session variables on each page and they are retrieved on the 4th and final page then submitted to a database when the submit button is clicked. When i was testing my program i filled out all 4 pages and then clicked back to refill-in something on a previous page and all my information wasn't filled out anymore. So i added the code in the page load sub btnBack.Attributes.Add("onClick", "javascript:history.back(); return false;") and this cured that problem so i could click back and the data would still be filled out.
Then i saw a new problem....after i went back to fix something on previous pages 1 and 2, i would click the next button to go forward to pages 3 and 4 that i've already started filling out and now the data on those pages were cleared. So how do i make it so that the information from the whole
program stays filled out whether i go back and forth from the 1st page to the 4th until i click submit on the 4th page?
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".

View 1 RepliesI am trying to build a form that will not change the URL in the users browser, and will not allow the user to press the browser back button. Is there something I can do to accomplish this?

Url: MyForm.aspx (still the same url)
I have a Deafult.aspx page with a form and a button. The form consists of a drop down list and a radio button list. When I click the button I submit the form to a different page, search.aspx. When I click the back button in the browser. Somehow the radio button list values stay the same as when I last clicked them (not any special configuration by my side), and the drop down list gets back to its default value. My radio button list has a on select event that changes the values of the drop down list. The problem is, as I mentioned, the radio button list keeps its former value when I submitted the page, and the dropDownList doesn't. So they are incoherent.
How do I make them both get back to their default values? (as this is no postback... right?) or how do I keep their former values. FYI, the problem doesn't occur in internet explorer. In chrome this happens. And in fire fox, it just gets back the dropdownlist is ok, but the radio button list's default selected index isn't even selected.
