I asked this question earlier, but unfortunately the two replies I got did
not solve the problem. Here it is again, but now with the code:
After an Update my FormView always loses its viewstate values. The field
values in the FormView are always overwritten by the results of the Update
method in the business layer. No matter what I do, the databind always takes
place, even when I don't want it to.
See the example below. This is a...

I have a formview bounded to an objectdatasource.
All ok but I have some trouble with a checkbox: when I am in update
mode and I update the record, this field is never updated (no errors
thrown).
The field bounded in the database (MySql) is a string field
(ENUM('True','False') default 'False'.
The checkbox is correctly bounded in the itemtemplate and in the
edititemtemplate.

Hello,
I read some msdn and other articles about how does databinding among
DataSource controls and FormView / GridView controls works but I still don't
fully understand to this blackbox. I have few questions and hopefully you can
provide me some answers.
1. Best place for DataBinding.
Where is the best place for calling DataBind method? Is it possible to say
don't bind controls for this postback and use current values instead? These...

Hi,
I have an object, for example User. User contains various properties which i
have been able to bind to successfully using wizards and the form view.
However if the class User has a property which is not a string, for example
a custom type Address which contains properties such as StreetAddress, City,
County, Country etc how do i bind to those properties on the same form view?
I have tried doing Bind("Address.StreetAddress") but...

I want do my insert to a database using a formview bound to an
objectdatasource. I also want to upload a file. I'm quite new to and this is
just test code but Is there any way I can pass the file as a byte array and
manipulate it in my business object. Currently what I have is this, but my
byte array in my business object is nothing. It's like it's not passed the
file as a stream. I think I am not binding the FileUpload to the...

Hi All,
I have a GridView inside the EditItemTemplate of a FormView. Both FormView
and GridView are data bound using an ObjectDataSource. When the FormView's
ObjectDataSource object has a SelectParameters with a SessionParameter in
the parameters collection and the object stored in the Session is a
reference type,
the DataGrid fails to enter Line Editing mode.
Is this a bug? Is there a workaround for this problem?

Hi All,
excuse me in advance for my not very perfect english. I need some help about
a problem with a FormView bounded to an ObjectDataSource. In practise I have
an ObjectDataSource that uses some BLL methods that implements the
optimistic concurrency by a TimeStamp field into the DB. So, when I execute
an insert, update or delete query if I receive 0 like return value from that
queries I understand that a concurrency problem is occurs so...

Hi,
Why does the Update method of an ObjectDataSource class requires
parameters for each of the Bind input controls of a FormView?
I have a class (say MyObjectDataSource) that is being used as an
ObjectDataSource for a FormView control. MyObjectDataSource has public
properties that correspond to db table columns and are also used to <
%# Bind("")%Input controls in the formview declaratively.
There is an Update method in...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
