I am using a formview with an ObjectDatasource in ASP .Net 2.0. Everything
works fine until I try the delete. The ItemDeleting event fires, so I know
it should fire my delete method, but instead I get an error: No parameterless
constructor defined for this object, and the delete method is never called.
Anyone have any ideas?

I am passing the whole object instead or parameters in my select and update
methods.
I can get the updated object if I set UpdateMethod, let ASP.NET autogenerate
an update button, and then press update after making changes, but I don't
want that update button.
How can I get the updated object when the user presses one of my other
action buttons?

I keep getting this error when trying to update records using an
ObjectDataSource. I have seen others post similar errors...but I haven't
found any solutions.
ObjectDataSource 'ObjectDataSource1' could not find a non-generic method
'UpdateProduct' that has parameters: ProductName, UnitPrice, ProductId.
I have been unable to work through this. Any ideas?
I’m using code pasted directly from this page:

Hi
I'm trying to get an instance of UserLists to persist after it's been used
by the GridView. I understand from the documentation that The
OnObjectCreated event allows access to the instance. I have a TotalUsers
property which is initiated when the GetUsers method is called, however it
is empty after the OnObjectCreated event runs. What am I doing wrong? Is
there a way to get the Row count from the GetUsers method (It is a
DataTable)?...

I'm using an ObjectDataSource with a stored procedure and am getting the
following error when trying to update (ExecuteNonQuery):
System.Data.SqlClient.SqlException: Procedure or Function 'UpdateRegistrant'
expects parameter '@EMail', which was not supplied.
The field value was null in the database and not changed in the FormView so
is null going back into the stored procedure. I'm stumped and would greatly
appreciate any suggestions.

Hi,
Recently, my site has been generating errors which say:
"Timeout expired. The timeout period elapsed prior to obtaining a connection
from the pool. This may have occurred because all pooled connections were in
use and max pool size was reached."
I'm wondering if this might have something to do with the way that we use
objectdatasource objects.

Hi ALL,
I wonder if anyone has been using n-tier to bind to a GridView control by
using the ObjectDataSource. This is our first OOP web application, and we
have no tables. Right now we are simply working with objects in memory.
So, it appears as though Microsoft requires that our datamapper classes
reside inside a folder called "App_Code", and NO WHERE ELSE.
So, has anyone successfully been able to place their datamappers in a...

Hi,
I have a search result GridView bound to an ObjectDataSource. Once I open
the asp.net page, the ObjectDataSource automatically refreshes the GridView
which is the default behavior.
I am trying to disable automatic query feature in ObjectDataSource, such
that it query the database only when the user click on Search button.
Is there anyway to prevent ObjectDataSource query the database when the page

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:

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...
