Web Forms :: Prevent URL Change In Browser When Navigating From One Page To Another?
Nov 13, 2013
i want to redirect from one web page to another web page in same server with some query string values, but i don't want to change my URL string and i don't want to display any query string parameters in URL.
How do I have a pop-up message come up that says "Are you sure you want to navigate way from this page? (OK) (Cancel)" when someone either clicks the back button or the close button?
The web app in question provides a UI for editing a client (in the business sense, not the browser sense), identified by a ClientID. I store the ClientID in Session, which gets passed from page to page, along with a number of other pieces of data in Session. Works great.
The problem is that if the user opens a new browser window using Ctrl N or File->New Window (in IE), the new window comes up with the same page as the current page, with the same session info. Then if the user navigates to a different client in the 2nd window, the ClientID in session refers to the new client. If they go back to the original browser window and save, the original client gets saved using the 2nd ClientID, and all hell breaks loose, because now the data from the two jobs are intertwined.
I have enabled trace and verified that the new browser window uses the same SessionID as the original. If an entirely new instance of IE is opened, it has a different SessionID, so is not a problem. I have not yet investigated other browsers, such as Chrome or Firefox.
Is there any way to determine if a browser instance is opened for a web app which is already open in another window or tab? Or to prevent that from happening?
My problem is am filling a form in a webpage, and click on save for instance, take the URL of mu webpage and paste it in a new window and it loads all the information I subscribed, how can I prevent that knowing that I used the Below code and it does nothing

I need to check information the user has entered on a page against what I have in my database to see if he is entering duplicate data. It is up to him if he wants to proceed or not. I just need to alert him.
The problem is I don't own the button that he clicks so I can't hook up a javascript confirm to the button click. I am running within vendor code. I have an "override PageLoad()" procedure where I can test what page they're currently on. If they are on page "EditForm.aspx" and would normally navigate to "UserFinish.aspx" without any custom code of mine "interfering", I want to test what they've entered on EditForm.aspx and present them with a popup if they've entered duplicate info, and if they click OK button then proceed to UserFinish but if they click Cancel then stay on EditForm.
Whenever there is a configuration error inside the web.config, the server sends a yellow screen of death to the browser with a few lines around it. My problem is I am using impersonation and I don't want the users to see the impersonating username/password. So how can I prevent the server from showing the web.config code??
In the web.config i am using as below. When the Login credentials are correct it should take to Products.aspx.Even when the credentials are correct this is displaying Login.aspx. Checked "Integrated Windows Authentication". Using IIS 5.1.
When I load the login page & enter user name the textbox of the password is showing the password I want each time I enter the user name, the textbox of the password being empty and I should enter the password myself...
I am running one application where one gridview is there when i am deleting any data there it shows one message for deleting.

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.
I am developing a simple email portal as my college assignment and I refer gmail for various features.Now when we sign into a gmail account and then if we hit the back button of the browser we somehow still remain on the inbox page.In my case after login if I press back button I comeback to the login page.
If I create a cookie in Javascript document.cookie = 'unseen' how do I delete it when I navigate away from this page? This is the only cookie I am creating on the page.
I have a couple of pages with standard asp.net validation controls such as RequiredFieldValidator etc inside my RadAjaxPanel.As soon as I navigate to another tab in my RadTabStrip the page seems to force validation errors and pretty much "locks" the page even though non of the fields was selected to enter data.Only once all the required fields was entered the page seems to release the "lock" and only then am I able to navigate to another tab / page without even submitting the page.
what might be causing the "lock" and forced validation errors on the page?
I am build Web site using asp.net 4.0 c# ... There are a forum on my website where user can save his personal details. my problem is that when user submit his detail in database and again refresh URL (f5), event again arise and request go to server, double entry saved in database. How I can handle it.
I am new to ASP.NET. I have encountered a problem in navigating the database records that is displayed in the web form , the Next and Previous buttons. I have 4 imageboxes and 2 textboxes under each image box for displaying database records.
I am currently using an Access database with a table "Images" and there are 4 columns in it. "ImageID", "ImageDescription","ImageofPicture","Description".
i want a pop up to be displayed when user tries to close the browser and if user click on "no" [i.e. he don't want browser to be closed] then it prevent browser to get closed.
i just like to ask if you have any idea of preventing the Back button of the browser to navigate back to the previous page after a user log in.Ex:After a user successfully logged in to my website and he/she hit the Back button of the browser.I want this to not redirected to the previous page instead redirected to the same page which is my Main page.Also after a user logged out to my website and again he/she hit the Back button of the browser.I also want this to not redirected to the previous page instead redirected to my login page.
I 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.
