Been a while since I've touched asp.net but one thing that always seems to
fustrate me is the loss of state on variable declarations. Is there anyway
(i.e. assigning an attribute etc) to instruct the server to remember a
variables state *without* having to go through the rigmarole of saving and
loading to and from the Session state manually or similar workaround for any
Types (including custom types) in exactly the same way web controls...

I have created a server control that reads data from an xml file and renders either a datagrid of entries from a database or group of form controls to allow editing of an individual entry from the same database. The Xml defines how the datagrid and edit form looks and what fields each displays.
The edit form display is perfect but I am having some problems with the datagrid list display.
The datagrid has sorting and pagination enabled and...

I have an app that was originally 1.1, now migrated to 2.0 and have run into
some sporadic viewstate errors...usually saying the viewstate is invalid,
eventvalidation failed or mac error.
My web config does specify a machinekey setting:

I have a CompositeControl with two types of properties:
1.) Mapped Properties that map directly to a child control's properties
(ex.: this.TextboxText = m_txt.Text). These properties are handled by their
underlying classes (such as the TextBox control), and are not persisted by me.
2.) Unique Properties that don't map directly and are persisted in ViewState
(ex.: this.LabelPosition, which specifies where on the form the label should

Hi,
I'm building a webcontrol that contains a dynamic list of other controls. My
problem is that when I add or remove an item the synchronization between the
ViewState and the Controls collection seems to break -- or at least that's
my theory for now.
Here's what I do; to add an item I do that following on the PostBack of a
button:
1. Create a Button object and set its properties

I am testing for how/when a page is posted back and I decided to use a
ViewState variable in PageLoad to set up a counter, but it appears,
the ViewState is cleared on each PageLoad. So then I used SESSION and
that worked.
Am I correct in assuming ViewState is cleared on each PageLoad or is my
code incorrect.

Hi folks,
we have a scenario whereby we're not too worried about cpu cycles on
the server, and much more worried about users with slow up-stream
connections to the server. Our goal is to...
1) Keep ViewState on.
2) Put ViewState in Session.
3) Compress the control state that gets sent to browser even when view
state is in session (since control state is always sent to the
browser).

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,...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

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...
