DataSource Controls :: Deadlock Transactions?
Feb 1, 2010I 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?

SqlBulkCopy Causes Deadlock On SQL Server 2000?
May 12, 2010I have a customized data import executable in .NET 3.5 which the SqlBulkCopy to basically do faster inserts on large amounts of data. The app basically takes an input file, massages the data and bulk uploads it into a SQL Server 2000. It was written by a consultant who was building it with a SQL 2008 database environment. Would that env difference be causing this? SQL 2000 does have the bcp utility which is what BulkCopy is based on. So, When we ran this, it triggered a Deadlock error.
Error details: Transaction (Process ID 58) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
I've tried numerous ways to try to resolve it. like temporarily setting the connection string variable MultipleActiveResultSets=true, which wasn't ideal, but it still gives a Deadlock error. I also made sure it wasn't a connection time out problem. here's the function.
/// <summary>
/// Bulks the insert.

SQL Server Deadlock While Inserting Rows In A Table
Oct 15, 2010The topic of sql server deadlock has been discussed many times, however, I was unsure that even two simultaneous inserts on a table can end up in a deadlock situation. Scenario: While testing our application (SQL Server 2005 as backend, ASP.net 3.5) we inserted records into a table simultaneously (simplified overview) and that resulted into a deadlock for more than 70% of users.
I could not get a hang of this as how an insert is being deadlock as this is not a case of multiple resources. After a detailed analysis (of reproducing the bug by two users) I found that both the processes were holding a RangeS-S lock on the primary key index of the table and were trying to convert this into RangeI-N lock, that resulted into a deadlock and one transaction being killed.
Question: Can we avoid or reduce these kind of deadlocks as this is not a case of change in order of access of resources? Cant' we force the transaction to get exclusive lock initially so that it blocks the other process and avoid deadlock? What (adverse) effects that may have? Also could some one explain more about RangeI-N lock.
Isolation Level for this was "Serializable".
DataSource Controls :: Running On Different Computer - Path Will Auto Change
Jul 26, 2010I created a DataSet(right-click project-->add new item-->DataSet) and then a TableAdaptor to it with table from database. However, when i bring the project to others computer and run, it has error.

My database file is located at the App_data folder. May i know is there a way to config so that whenever i run the project on different computer, the path will auto change?
DataSource Controls :: SQL Server 2000 - Event Log Error Id - 318
Jan 7, 2010Unable to read local eventlog (reason: The data area passed to a system call is too small). This error is recorded in the event log every minute in the production server, and because of this the SQL Server 2000 performance is very slow and the box is also working slow. This indirectly affects my application and productivity.
