I created simple ASP.NET web application to test how AutoPostBack property
in a web control works.
I set AutoPostBack property to be true of a web control. When I run the
application, here's the sequences when I step through the program:
1. Page loaded to the browser
2. Page_Load method is called with non-postback event
3. The user has certain actions on a control
4. Page_Load method is called with postback event

I did a ton of searching to try and find a simple solution to this issue and finally wrote my own, which I am sharing with everyone. In my searching, I did find a very complete and robust solution at
http://weblogs.asp.net/asmith/archive/2003/09/15/27684.aspx
but it was far more complex then I needed. (I got lost trying to figure it all out). Therefore, here goes my simple "web dialog box with parent event handler fireing" solution.

I'm new to ASP.NET and I'm not use to the way things are handled with
this technology. I've been told that when I have a control, I should
only bind the data to it once, and not on each post back (basically
have the data binding done in the If NOT IsPostBack Then statement).
How come? How does this information get preserved?
Which raises another question. Becuase I want to get away from the
spaghetti code approach, I would like to create...

In our multi-tier application, we have several ASP.NET user controls which
will update the same data source provided by middle tier logic.
In this particular scenario we have one user control displaying the contents
of the data source, whilst another control updates the datasource via a

Postback Events' stage of the control execution life cycle (via the...

It would be udeful to be able to get the current on-screen values from a
FormView that is databound to an ObjectDataSource by using a callback instead
of a postback. For example:
public void RaiseCallbackEvent(string eventArgs)
{
// update the data object with the values currently on screen
FormView1.UpdateItem(true);
}

Hi all,
This is my first message here so i'll try and include all the
information that will help you help me out, if possible.

I know that this has been asked and answered thousands of times. As a
matter of fact, I know that I need to say
If Not Page.IsPostBack Then
'Do something
End If
for things that needs to be processed by the web server. I am still
struggling to understand this postback logic, and hope that some kind
gurus out there could help me clarify the confusion I have.

Hi guys,
I am converting a rather complicated database driven Web application from
classic ASP to ASP.NET 2.0 using VB 2005 as the programming language. The
original ASP application works quite well, so at times it is tempting just
to port parts of it over mostly as-is. In fact, one MSDN article I read
suggested using straight HTML wherever possible to make the app more
efficient and less resource demanding.
On one page there are 2...

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

Let's talk about the concept of autonomous AI software engineers and no-code agents. 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...
