I'm at a loss here...
My FormView control automatically performs a databind at each postback on
the server. But in some cases I don't want this to happen. Like when the
business layer decides that some of the information in the controls cannot be
accepted. But then the FormView binds to the datasource again, and the input
in all contols is lost. And the user will have to type it all over again.
In ASP.NET 1.1 we could simply say: If Not...

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...

Hi, I'm a newbie to ASP.NET programming but not to Visual Studio.
I'm having trouble getting my Master-Details page to work. I have a
page enabled GridView which is linked to a FormView control through an
objectdatasource. The paging on my GridView works fine except that when
I change the page the FormView
does not update. I tried setting the selectedindex to 0 in the
GridView's PageIndexChanged event and manually binding the formview...

When Updating using a FormView and ObjectDataSource, the formview
always does the data-binding of its controls and the field values in
the FormView are always overwritten by the results of the Update
method. This behavior is fine when update method succeeds.
But the problem is that when for some reason (e.g. a business rule
"start date can not be prior to 1/1/2006") business layer rejects
the data and Update method returns False (or...

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.

I have an object.
Theres a get, update, insert (etc) method for this
The Get rturns an IList which I bind to a formview via
objectdatasource.
In the get method I store the object in session once I have it, naming
it object+id.
I first check to see if the object is in session and I return that if
it's already cached.
On insert update and delete I clear the objet out of session cache.

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...

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

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,...

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...
