Web Forms :: How To Disable Backspace To Previous Page
Oct 27, 2009
I feel like I'm really close but yet so far away with this. I have a form and when the user hits the backspace button when focused on the web browser I don't want it to go to the previous web page -- but I still need the backspace button to work in textboxes in the form.
I was just typing on an old site of mine that requires the constant contact method that uses threading and an update panel to prevent users from being logged out since despite setting the timeout period in web.config to what mathematically should be millions of minutes people still seem to get logged out after like 5 minutes. I tried the web service method, but it was ineffective.
The constant contact with an update panel accomplishes its primary objective well, however when a user clicks on their keyboards back button at the wrong time they get redirected to the previous page and if they click the forward button in their browser the page contains none of their typed data.
Is there a way to override whatever causes the backspace button to do this?
I am having 2 web formsand will have a drop down list on those web forms. If i select a value from drop down and click on ok i will get tranfer to next page. In that page i will have a drop down with the same values in the previous form . What i need is i would like to disable the selected value in the previos form and would like to display the remaining normal.
On my current project I want to deny going back once my customers hit submit button and redirected to the final page. How can I deny from going back to previous page or some mechanism to expire the page if the back button is clicked. I tried this code and it didn't work

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.
I'm looking for a simple solution to disable the IE functionality of the backspace key behaving like a back button. I have textboxes that are dynamically set to read only depending on certain criteria. If the user hits the backspace key when focus is on a read only textbox it navigates back a page. I would like to disable this functionality.

I am working on a web site that will be a testing website. On the first page (frmSelectTest.aspx) the user will enter his username, password, select a test to take then click a button and a new page(frmTakeTest.aspx) will open with the test questions. After taking the test the user will click a button to grade the test and he will automatically be taken to another page (viewResults.aspx) where he can view the results of the test. After viewing his test results there will be a link that will take him to another part of the website.
I donít want the user to be able to use their browser back button to go back to the first page (frmSelectTest.aspx) from the test page (frmTakeTest.aspx) or be able to use the browserís back button to go back to the test page(frmTakeTest.aspx) or back to the select a test page (frmSelectTest.aspx). I havenít been able to figure out how to disable the browser back button and prevent the user from returning to previous pages.
I can user Server.Transfer which seems to disable the browser back button but it doesnít work consistently, sometimes it works and sometime it doesnít. I have searched the internet and found several examples but I couldnít get any of them to work.
Some things Iíve tried in the page load event but canít get to work
Response.Cache.SetCacheability(HttpCacheability.NoCache) Response.Cache.SetExpires(DateTime.Now //or a date much earlier than current time Iíve also tried:

I am using Pageddatasource to do customised paging on my repeater, i have a button which allows a user to remove items, my problem is that if the user deletes an item and they are on the last page, after deleting it stays on the same page even though that page is empty, when in fact the correct thing to do would be to go to the previous page, how do i do this. This is what my code currently looks like;
