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record (without edits) should be amended to be: ent_key =1000, seq_key =3, cur_key =0 (this 0 indicates that it is no longer current)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.
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.

The website is over half way done and the functionality for the blog is (except for adding posts) is already implemented and working correctlyI have a SQLExpress 2008 backendBlog posts are rendered on the page with full HTML markup within a label control.
All of the above is done and working. Though I am essentially new to creating websites with ASP.NET, CSS and SQL, I am sure that I could simply carry on and make a login page with some controls that would allow me to add records (blog posts) directly to the database on the host server. However, I am fearful of doing this because I know that malicious code can be passed in this way. Also, because of my lack of knowledge, the only way that I know of to pass the code from a control to the database is to disable validation for the page the control is on. Without a doubt I do not want to do that.
So what are my options for getting blog posts into the database? Is it safest for me to fully create the post in html and update a copy of the database that resides on my local machine? If I do it this way, how can I merge the records from the database on the local machine with the records on the remote server?

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.
I have applied audit trail to my webform/table its working fine.I am able to maintain the History(action,action_date) of the MySql database table from ASP.net but I want to save user name i.e action_by too so i will have history of who changed the data and when, how can i acheive to save username in history table.i have login webform in my application. History MySql Table.
i dont know at what instance of program i have to do this while adding the history point or in the navigate event of script manager(i mean calling javascript function from code behind)
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 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.
