Deleting History Pages In .net?
Oct 21, 2010
How to delete the history pages in ASP.net?In my application when the user logs out, i delete the session variables and expire the cookie(aspxauth and asp_net_sessionId) but however when user clicks on the back button of the browser, user could still see the pages with all the user information on it. However the page cannot interact the server as sessions are not available but expired pages contain demographic information which is an harmful scenario for Security issues.

I have a website which contains several ajax enabled pages. I need to maintain state in each page. I have added historypoints in each page. My back button works fine as far as I am on single page. But when I visit different page and then click back button to come to original page, only the last history state for that page is loaded and all other seem to get wiped out. What I mean is, clicking back button again takes me to previous page instead of loading same page again from history point. Is there any way to maintain history points even when I visit different pages

What I want is that I can add /edit or delete view pages. I don't want a complex content management system , just looking for any examples where one can add simple view page, I have no idea how to add action result dynamically, programatically on a controller page in mvc2.

I have a repeater which binds a set of data. Within this repeater is a column with various controls for updating, deleting, etc. These are image buttons which fire an onclick event such as "DeleteRecord". All this does is fire a stored procedure, passing in the ID of the record to delete from the CommandArgument of the object.
This works wonderfully... except for one rather huge problem. Once you delete a record, if you refresh the page, the record where the first deleted record used to be gets deleted. For instance... if I have 4 records
1 Record1
2 Record2
3 Record3
4 Record4
and I delete record 2... The page reloads with (which is fine):
1 Record1
3 Record3
4 Record4
...if I then hit refresh...
1 Record1
4 Record4
I assume this is because the erroneously deleted object (record3) is now in the same hierarchical place as the old object used to be and .net therefore doesn't know the difference, the page refreshes and fires the onlick event, grabbing out the command argument of the new object and deletes based on the ID as obtained from the commandargument of the new object. This is obviously a huge problem, if a client did this it would destroy data erroneously and I'm at a loss here. Is there any way to stop this from happening? I'm not sure if there is a better way to go about doing things or not. If there isn't, I need some sort of way to tell the page not to execute the event or to cross reference the ID of the object that is intended for deletion against the object itself...
Code below for convenience...
EDIT Wrapped a LinkButton around it because I have some jquery code in here as well which stops the page execution to wait for user confirmation. Pressing "ok" continues page execution.
<asp:LinkButton ID="oDeleteLink" CssClass="oDeleteIcon" CommandName="Delete" CommandArgument='<%# Eval("iAccountID") %>' runat="server">
<asp:ImageButton ImageUrl="/files/system/icons/trash-steel-16.png" ToolTip="Delete This Account" AlternateText="Delete" ID="oDeleteIcon" runat="server" />
</asp:LinkButton>
protected void oAccounts_ItemCommand(Object Sender, RepeaterCommandEventArgs e) {
if (e.CommandName == "Delete") {
int ID = e.CommandArgument.ToString().Numeric();
db.SPs.SpDeleteAccount(ID).Execute();
UI.Confirm(uiBroadcast, "Account has been deleted", "300px");
BindAccounts();
}
}

I am wanting to develop an application where there is a business requirement to keep a track of all changes made, so every time a record is edited, it is saved as a new record. So far, I have a Search form to list my Entities in a GridView. When I have identified the Entity I want to edit, I click on that record, and it takes me to a DetailsView form, with all fields of the record. Every record is identified as having an Entity key (ent_key), Sequence (seq_key) and Current key (cur_key). When I edit and save the Entity with say, ent_key =1000, seq_key =3, cur_key =1 and make any changes, then two things should happen:
1. the existing record (without edits) should be amended to be: ent_key =1000, seq_key =3, cur_key =0 (this 0 indicates that it is no longer current)
2. a new record including edits should be inserted to the database as having: ent_key =1000, seq_key =4, cur_key =1
The problems: In my DetailsView form, in Update mode I cannot update the seq_key, and when I use Insert mode, all the fields are blank so this is not helpful to the end user. (FYI - The data is stored in a SQL Server database, and I have set up a table adapter to retrieve the records. Am developing in C#)I would like to utilize stored procs where possible to resolve this issue. Would you experts please help me with some ideas (incl coding and examples if poss) to resolve this issue? Am reasonably new to this development, and I don't know what I don't know.

I have couple of DDL's, namely DDL1 and DDL2. The latter is dependent on the DDL1, which is creating some problem for me. When I choose a value in DDL1 it populates DDL2 accordingly but when I choose a different value in DDL1 it still shows the result from my previous selection in DDL2.
How do I remove historical values from DDL2 and only shows values matching to what is selected in DDL1.

I'm using 2 masterpages in my project.One master page is for login page and another one for the HomePage where user will go thro the options to reach other pages from home page..The thing is,i have "Logout" button in my home page.When i click on the logout button,the page will be redirected to "LoginPage.aspx". After redirecting to login page,when i click on browser back button,the previous page is displaying but it should not display to user since i'm doing sensitive transactions in all pages...
I tried using following code
Code:
Response.Expires = 0;
Response.Cache.SetNoStore();
Response.AppendHeader("Pragma", "no-cache");
Page.Response.Cache.SetCacheability(HttpCacheability.NoCache);
but it's not working...

I'm using asp.net AJAX and history points with the ScriptManager and it works great. My only problem is that when I make non AJAX pages I have come to love url-rewriting with nice "hackable" urls. Without SecureHistoryState my url will look like for example [URL] where "/Home/Frontpage" is the page to show. I have seen on other web-pages with AJAX (maybe not asp.net) that the url will change into for example [URL] which is a lot nicer. Or if I could have[URL]I would be very happy. I don't need the history url to contain anything else than the page path. Is this at all possible with asp.net AJAX?

I am using a ScriptManager control to load search results from server web services. There is a text box and button on the page where the user enters their search terms. When they submit their search there is a Response.Redirect that is called to the search page. I use the ScriptManager's history function to track filtering that the users can do. If you are familiar with this function the URL ends up looking something like this:
[URL]
My problem is that if the users deices to do another search with the text box and button on the search.aspx page, which causes a response.redirect, the query string changes but the hash history stay a part of the URL. This does not make sense to me because from what I understand of the Response.Redirect("someURL") it should act like it is sending you to a new page regardless if it is going to the same page it left.

we have a web form with check boxes on.
When we click our back button the page only returns to the previous state (un checking the check boxes one by one after each click). We would like it to go back to the previous page and remember the history of the page.
I've tried :
[Code]....
but this just crashes the page.
our javascript button looks like this:
<input type="button" value="Back" onclick="history.go(-1)" />
(the browser back button does the same thing)

I want to add the History Control to my Ajax Extensions Toolkit.
I'm using Visual Web Developer 2008 Express Edition Version 3.5 SP1
Is this Possible? - cause I understand Visual Studio 2008 Standard Edition SP1 already includes these Ajax Extensions.
If it is from where can I find the right download?

I have a requirement to keep a history of values of some fields in an EF4 ASP.NET MVC3 application. This just needs to be a log file of sorts, log the user, datetime, tablename, fieldname, oldvalue, newvalue.
Although it would be pretty easy to code this in various save routines, I'm wondering if I can get global coverage by wiring it into some sort of dataannotation, so that I can perhaps declare
[KeepHistory()]
public string Surname { get; set; }
in my partial class (I'm using POCO but generated from a T4 template).

i am using the function history.go(-1) function on my button to go back. but i am getting a prob in value selected in dropdown.
the sourceview is showing the original value selected but on UI its showing the previous value
means when i click on back button,
UI shows the same value but when i view the source code then the selected value is the same that need to be appear
for example
suppose my dropdown has data in format MM/YYYY first i select 02/2010 and then after that i select 04/2010 now when i click on back button having onclick ="history.go(-1)"
then the value in dropdown remains the same i.e 04/2010 but when i see the source code, then for dropdown the selected value shows as 02/2010.

i have a master page that has a an accordion and inside the accordion is a cscading dropdownlist and then a button... Basically you select the values from the dropdowns and the click the button to change the content form from default.aspx to history.aspx. This works fine the first time I do it with the exception that cascadiing ddl all reset and then if i populate again and clcik the button again I get the following error(below)... I know I can set enableEventValidation = false, but wondered why this is occuring and what effect setting it to false would have? The second part of the question would be how do I maintain the ddl values when the page changes from default to History.sapx? I am using the following for the button.
<asp:Button ID="btnNewRecord" runat="server" Text="New" PostBackUrl ="~/History.aspx" />
Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true"
%> in a page.
For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
