I have a requirement to log all/most forms authentication transactions that take place within my page. For example, if someone is kicked out because of forms authentication, I'd like to get their username, time when kicked off, and where this happened. Is there a good way to do this. Better yet, has anyone done this already and is willing to share some code or post a link?

Example: we have different articles in a database like cars, jewelery, boats. The data related to these articles is different in the tables. I have to show that data in a textboxes and let the user change those data and update. I can do the update and reading the data from database. But the problems is for each item the no.of columns and rows will differ.
My task is I need to get the data according to the use selection in the table with textboxes. I dont know which container (gridview, formview or etc) will suites for my requirement. send me any sample code or any tutorial related to this.
Note: showing the data in a table should be a constraint. Because I should show data row wise (each row contains 3 textboxes and 3 labels (DB table column names))
I would like to create those checked/selected rows in gridview to SQL server database with a button click.For example, an user checks 2 rows in the gridview, and clicks on the create button. I would want the selected row/s to be created to the database. How would I go about doing this?
View 4 RepliesI am working on a medium size web site and I am kind of stuck. I need to do the following
1- admin user fill a form and submit (Done)
2- the system create new page storing the info provided in step 1
how can I do that? I need a page to be created I don't want to read the data from data base and display it on a template
On my webpage, jobs.aspx, I have a gridview which is populated from my database. I would like it so that when a row in the gridview is clicked, the ID of the row from my database can then be passed through as a query string to a second webpage, details.aspx, where more information about what was clicked on will be displayed.
I'm confident about being able to pass the query string, I just need help with getting the corresponding row's data ID from my database and making the gridview click-able, which will be the interaction which specifies which ID to be retrieved.
Ive created a web site using VS2008 ASP.net and connected to a Firebird Database.
I have a page that has a GridView(added at design time) and have connected to a table at runtime.
[Code]....
All good as the table contents are displayed at 10 rows per page. Ive set the Property AllowSorting to True. Has anyone got examples on how to code the sorting? Ive had a look round the net but all the examples Ive tried dont work.
I have two databound controls on one page. GridView, DropDownList. My page is crashing with a SQL Transaction deadlock victim error. I would like to capture this error, and attempt to re-databind the controls. My first thought was to handle an event on the controls that allow me to do this, but I don't see which event to handle. I couldn't search any answers. Where should I begin?
View 3 RepliesI am a web developer handling back end frond end both.My question is that which transaction should I use
to maintain ACID. whether transactions in Sql Server or transaction in Ado.net?
Are there any transactions around multiple webservice calls.Let me start with a commonly used example -- the travel agency. A customer intends to create a travel plan through an online travel agency. To do this, the online travel application calls the following three Web services:
-Air ticket booking
-Hotel reservation
-Taxi reservation
These three services are available from three separate vendors. If any one of these three services fails, the customer does not wish to proceed with the transaction (again, either all three services must succeed or none at all).My language programming is Asp.net c#.
Are there any transactions around multiple webservice calls?but in ASP.net forum I got the answer below:
http://jalpesh.blogspot.com/2010/05/using-transactions-with-linq-to-sql.html it's offering system.transaction.
I have an application which connect to oracle db.
I have two database hitting functions.
One is adding Userdetails(Fn Name : AddUserDtls) and another one adding address details(Fn name : AddAddresDtls) based on UserName which will get added after execution of first method ie AddUserDtls.
Problem I am facing is :
I have a single transaction and in that I have all the methods.
After the execution of first method,with out commiting i will go to second method.
and if any error occurs in second method.
I will rollback everything including the changes made by first method also.
Here one issue is there.
Since I am not committing the changes made by first method,
While I am executing the second method I am getting error that 'No user Name exists'
I understood that if we commit the transaction before the second method starts ,it will solve the issue.
But then it creates another problem.If some problem araise in the second method,then I cannot rollback the changes made by first method since it aleready commited.
I am trying to delete three related objects on one submit. Delete fails on one of the child objects, because of foreign key contraint with another table, It deletes one (the parent) but not the two child objects. All in one SubmitChanges(). I even used the TransactionScope, still same thing. So here is the scenario:
I have an object called Page which has a collection of objects called Webinars. There is another object Called Product which is one to one with Webinar.

View 3 RepliesHow do I ensure and enforce that all write operations to my MS SQL Server DB are transactions-based?
The reason I want to do this is that the DB contains financial account data and operations that fail halfway through some set of changes should not be able to mess up the database by mistake or by crashing.
The application is written in ASP.NET C#.
Edit:
There is a DAL but it does not (yet) require transactions for changes.We wrote the DAL ourselves. We did not use ORM.
I know how to perform one transaction from ASP.NET.
I want to ensure that all changes are made in transaction form so that if the application throws some exception in the middle, there will be no change to the database.
I have a DataSet that I have added to my project where I can Insert and Add records using the Add Query function in Visual Studio 2010, however I want to add transactions to this, I have found a few examples but cannot seem to find one that works with these.
I know I need to use the SQLClient.SQLTransaction Class somehow. I used the Add New Data Source Wizard and added the Tables/View/Functions I need, I just need an example using this process such as How to get the DataConnection my DataSet has used. Assuming all options have been set in the wizard and I am only using the pre-defined adapters and options asked for in this wizard, how to I add the Transaction logic to my Database.
For example I have a DataSet called ProductDataSet with the XSD created for this, I have then added my Stock table as a Datasource and Added an AddStock method with a wizard, this also if a new item calls an AddItem method, if either of these fails I want to rollback the AddItem and AddStock in this case.

I need to modifiy my web applicaiton without affecting current transaction.

Is there any way i can update my changes without affecting transaction.
I have a big web application on asp.net 2.0.Usere open object editor there and makes some changes. They can not open the same object at one time.After they press "save" btn all changes process to save on server via postback.I am using transaction for save. There are a lot of procedures, checks and others to be done before saving operation is OK.
using (SqlConnection con = .........)
{
SqlTransaction trans = null;
try [code]...
For me this code is quite safe.
But periodicaly happens:one process from this web application on saving operation on mssql became "sleeping/awaiting" and others processes called by other users became locked by this process and organiza a queue.
One of them threw timeout excetion.....but others are waiting.So, my question is: does my code have some bad operation that allows command to became sleeping/awaiting?
I am building an aspx page using c# and Visual Studio 2008. can anyone help to answer this question,Q1. When a page has add/edi/delete features by calling stored procedure or sql inline code (within the aspx page) It may cause issues in this senario:two users accessing the same page, lets say they both at the same time are editing the same record. a third user is only viewing that same record. how can I control such senario who get to make the change first.Q2. if the thrid user accessed the record after the first user change the records, but before the second user change the record. is he going to see the origional record or the updated record done by the second user.Q3. if the third user opened the record to view it before the first user make any changes, so he is opening a grid view , lets say the first user make a change. The third user will still see the old record...right, so he is not viewing updated record.how would he know that the record he is viewing is not current?If anyone can explain the senario and also would appreciate if you have any documentation or URL reference to searh .
