I have a detailsview which has a button for insert and edit depending on mode plus a cancel button. What I am looking to do, is to use the cancel button to stop any insert or update to the database if clicked.

Creating a system with web front end and SQL backend (microsoft obviously). I have tried using the asp.netsqlprovider but i can;t as i am only allowed one database on the server, so i then tried to update my current database with the triggers to input the schema into the already existing database.Next step i create my own table with two simple fields of username and password and try and authenticate that way, i can't get that to work either.
I ahve limited permissions on the network as i am a University Student. I really don't know what to do. Never had to create a log on system before and i thought it would be far simpler than this. I ahve used Microsoft's sqlprovider schema before and it worked fine. I have also authenticated via IIS and AD too before. I can't do any of those two in this instance it seems.I need an alternative for logging in users, if needs be in can be crude. I also still need to have some kind of two different views too for logged in users and not logged in users, but that can change if needs must.Don't let me down people, haha. Think this posts in the correct place, i could not find another one i thought could be more relevant.

in my case, It is the windows service which in running the long running insert/update on a table and I need to cancel the operation from my ASP.NET application. In the above link Burnsys suggests that one should kill the Sql server session. Is that really only way and a goood practice to do this? Also, in the same poset can use SqlCommand.Cancel to cancel. However, I am not sure how can I cancel the command from the windows service from ASP.NET application.

I'm fairly new to asp.net and I'm trying get my arms around the data entry and update. I have created a nice data entry formusing a stored procedure. It works well but for a test database, it's pretty much overkill, but worthwell in learning how. I'm going through the ADO.NET quick start tutorial and I've ran across a couple of questions that I've not be able to answer. In my website,I'm wanting to edit the database by creating a separate form that is filled with the existing database information for that particular id. My main question is how to I take the information from the dataset and get it into my form. The code below is not fillingmy form. Not sure what I should be using here:

I have a table with Id, Name,...IsActive, etc. If user wants to delete a record from the user, he/she should update the field IsActive to false. I am able to acheive this functionality using the below steps,
1. Query the database for the row which is to be updated.
2. Update the property IsActive to false.
3. Submit the changes to the database.
This way i am successful. But i have a query here is that, when we execute steps 1 and 3, there will be two trips to the database for getting the required object and again updating the same object to the database.
Is this not a performance hit having multiple calls to DB for a simple operation.?
Do we have any other go, where in within a single call to database, can i update a field of row?

I am using a LINQ to SQL data source for a ListView and perform a validation check in the Listview ItemUpdating event:
[Code]....
This works great and keeps the user from updating the record with invalid data.However, when I hit cancel after this operation, it saves the text in the box rather than cancelling the operation. Here's my code for the update button:
[Code]....
Update Function:
[Code]....
I do not handle the cancel button event, as the cancel operation has worked fine... unless someone enters incorrect information and e.Cancel is set to true.What am I doing wrong? Is it the mixture of using the LINQ Datasource and doing my own updating?

I'm attempting to create a update form that will pull information from my database. I'm a little confused on how to get the information into the textboxes on my form. First I have my form:
[Code]....
This is where I'm getting stuck. I'm not certain what code I need or if what I have is correct. Is there an example what my next step(s) are? I would think that I need to set a variable to hold the data, maybe something like txtRace = Trim(GetString(0)???
