Web Forms :: Getting Back / Forward Buttons To Work Correctly?
Aug 31, 2010
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?
How should i handle browser Back and Forward button? I have aspx page . in aspx page has some field with Save Button. i have clicked on save button to save the data, then i clicked on browser back button, then it again execute the save button event. how should i prevent to fire save button event again when user clicked on Browser back button?
I am doing online quiz in a Page in my website. How i will restrict users from going backward or forward using Broowser backward or forward button in that page using ASP.Net,C#,JavaScript.
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.
I'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 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 have a gridview that does a select statement against a sql database, there is not editing, inserting or deleting just the select statement. 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.
I have a 2 groups of Radio Button controls on my web page that are dynamically loaded. They are contained within a DataList control. I have the "GroupName" property set for each of the groups, however, I am still able to click on more than one rdo within each group. I've set the "GroupName" property within my HTML markup.

I want to display a warning message and then open a panel on my form in response to a button click in my gridview.
I have used this on another form with a delete command in a gridview column and it work perfectly.
Why isn't it working with my select command ?
Here is the code:
<asp:LinkButton ID="LinkButton3" runat="server" CommandName="Select " OnClientClick = "return confirm='Are you sure that you want to delete this record ?');">Select</asp:LinkButton> </ItemTemplate> </asp:TemplateField>
If I have the case where one button is set when the page is displayed and the user changes to the other value, BOTH are coming back as TRUE. How can I just get the value selected by the user?
when i am trying to use a repeater to display data in a wizard control, everything seems worked as expected before i change the value of wizard's DisplaySideBar, here is my demo code:Test.aspx:
[Code]....
Test.aspx.cs:
[Code]....
guys who intrest on this you can copy this code and test it on your pc, when we click the link button in repeater's item will do nothing at the first time but it will work when we click it again.i have debug this and found that when the page is not in post back, the linkbutton's id will be "MainWizard_rpMain_ctl01 _lbEdit" in prerender method but after render it will change to "MainWizard_rpMain_ctl04 _lbEdit", but when page have been post back, the clientid will be correct as "MainWizard_rpMain_ctl01_lbEdit" and then event can be fired correctly.i thought this is a bug of .net framework, when i set the value of wizard's DisplaySideBar, it will ask to re-create controls but repeater haven't clean the item's count and then recreate item will use wrong item index, i hope this message can be post to .net framework team and they can find out what's the matter on it.
Why might gridview only work correctly after reloading the page in IE? And, why does it work correctly on the first page load in Firefox? How might I solve this problem? I thought of trying to instantly reload the page with Javascript if the browser is IE, but this is kind of a bad workaround.
I need a Listview that will show info from several database tables. My delete button, will not delete the record from the database. I cannot get DeleteOnSubmit() to work at all. I am in the very beginner stage. This is my first project. I thought this would be a good project for learning purposes.
I have a asp.net app that I want to disable the buttons as soon as they are clicked in order to prevent multiple submissions. I'd like to use jquery for this as the site already liberally uses it anyway.
I have a view with 2 submit buttons. Both must submit the form data to the controller, but the actions the perform are different.If the user clicks Button A, the form is submitted, the model is modified, and the model is returned to the form with some updated information. I'd also like to make a visible if Button A was clicked. So, initially, the is not visible, but if button A has been clicked, when the view is re-displayed, the must be visible. (Possible?)
- Create a gridview with AllowPaging and AllowSorting = true - On page load, I bind it to datasource (in my case a webservice) - On gridview's rowcreated event, I dynamically add image buttons on the header of the grid for sorting (up/down arrows). On header I have column name and the image. I removed the Column name default sorting link. So user can now only click the image button for sorting. - Call sorting method
This works perfectly fine without AJAX. The paging, sorting works fine. Also when I apply AJAX the paging works fine. But the sorting is doing a full post back instead of partial postback.
I have my gridview within UpdatePanel and Triggeres is set on gridview sill it doesn't work.
I have a User Control (ascx) and a property which a want to display in my categories tab in Visual Studio in the category named "Styles".
[Code]....
And here is the problem: Actually I do not need a get, because I only have to set the property (write only property). But when I omit the get, the property is displayed in the "Misc" category in the categories tab in Visual Studio. Only when I code the get as well, then the property is displayed correctly in the "Styles" category in the categories tab in Visual Studio.
Does anybody know why? How can I display the category correctly only with set?
