Is there a way to turn off optimistic concurrency in ASP.NET when updating a
record via the oleDBdataAdapter/oleDBcommandBuilder?
If you use the Microsoft ASP.NET tools you can turn it off and thus modify
the SQL statement so that it doesn't include the WHERE portion, but I'm not
sure how to do the same thing in the code. I do my code-behind in VB.
Thanks!

I've chosen to implement the "optimistic concurrency" model in my
application. To assist in that, I've added a ROWVERSION (TIMESTAMP) column to
my main tables. I read the value of the column in my select, remember it, and
then use it in the update. It works just fine when I have full control of the
whole process.
I want to do the same for my GridView/SqlDataSource combinations. I
typically select from a view and update the corresponding...

In 'Data Adapter Configuration Wizard' for OleDbDataAdapter, there's a
checkbox called 'Use optimistic concurrency' that allows to turn on/off the
option. I don't use the wizard, I create MyDataAdapter using the following,
MyDataAdapter = new New OleDbDataAdapter(MySql, MyDatabase)
The question is how to turn off the 'Use optimistic concurrency' option in
my case. Thanks.

Hi,
I'm using a detailsview control with an SqlDataSource control. My
Update query isn't working, and I've narrowed it down to the optimistic
concurrency parameters - i.e. when I comment them out of the query, it
works. What seems to be happening is that if a field is NULL when it
is read in through the select statement, it's causing the update
statment not to find a match. I've got ConvertEmptyStringToNull not
set (so it should...

I have a DataGridView bound to an MS Access table. This is a single-
user application. When the User is adding or editing a row, the User
may click on a Control elsewhere. That Control has context which I use
to programmatically set *other* r/o cell values for the currently
selected grid row. So, after that click on another control, and
stuffing the related cell values, I want to seamlessly allow the user
to resume editing/adding that row...

I was suddenly told to whip up a web project in ASP.Net 2.0. The last few
weeks have been a crash course in new technology. I've done some 1.1 web
work but it's been a while. The basics are really quite simple and I want to
keep it that way. I'm using virtually nothing but grid views and
detailsviews. The grids are used solely for display. Each row has an edit
hyperlink that goes to a detailsview for actual edits and inserts. The...

(If I'm overlooking anything, please let me know.)
First, my only concern is updating single records in a Detailsview using an
ObjectDataSource. The target table has a timestamp field. Assume a single
primary key.
Create your xsd. Drag the table onto the xsd. Then manually edit the
Update statement to simplify it. Essentially 'Update <tableset blah = blah
Where (PK=@PK) and (ts=@ts)'. (Get rid of all that auto-generated...

Hi,
Sql-Server 2000, 2005.
A report fetches a lot of rows using the "WITH (ROWLOCK)" syntax (the
sql is generated on the fly by a tool and not easily changeable).
SELECT col1, col2 FROM mytab WITH (ROWLOCK) WHERE ...."
The select-clause runs for several minutes.
Another user fetches one of those rows and tries to update it. The
result is a lock timeout.
