Hi,
I'd like to find out the control that caused a postback to be raised. Obviously this could simply done in a control event handler. I am not going to do this method and would like no references as to how to do it this way as I already know how.
I know this may be getting into advanced or unheard of territory.
I have some custom web user controls that are dynamically created at run time along with other controls. I can still add an...

Hi friends,
This is my question....
From the Page Load event (or Page Init event), I would need to find which
event had occurred that caused a PostBack, for example was it a event fired
from the datagrid that caused a postback, or was it from a linkbutton, or
was it from any other control on the page that have PostBack capabilities ?
I am pretty sure this information is captured somewhere before the event is
sent to its appropiate...

I have half a dozen web form radio buttons on a web form. Each of them is set to postback=true. However, if for instance radiobutton1 is already selected and the user selects it again, it performs a postback.
I only want to do a postback if the value of the radiobutton is changed.
What is the best method to accomplish this?
thx

When I navigate to the next page using
Response.Rediect("MyNextPage.aspx") current page Page_Load event is called.
What I may wrongly understood is that post back will happen whenever there
is any server side event happens, resulting in Page_load event. Page_Load is
also happening when I navigate to the next page. That means Page_load will
always happen when I navigate to the next page. Please correct me If I have
totally misunderstood...

For some reason I cannot get the OnSelectedIndexChanged event to fire for a
listbox I have on a page. I'm able to populate the listbox with data from a
stored procedure, but cannot trigger the event. I do have EnableViewState =
True for the listbox. I'm imagining (wanting) to populate the listbox named:
lstNames by using the DataValueField from lstDepartments.
It's quite apparent though that the event is not triggering as I can misname...

In diagnosing a problem, I noted that a button_click event gets run only
after the page Page_Load event of the post back. (VS 2003, ASPNET 1.1, C#)
Can this be correct? I'm trying to set session variables in a Button_Click
event which determines how the page is supposed to appear in the PostBack,
so of course it fails.
Where should I put my code so that the session variables are re-set before
the PostBack?

Hi,
I have been developing web applications for a while now.
However, as I was thinking through the architecture I really don't
understand the "How server can identify between which buttons has made
the postback request.???"
for e.g.
I have a webpage default.aspx.
I place TWO or more server buttons on it.
Create server-side event handlers for each of the buttons.

We have a base class that is responsible for creating the navigation and look
and feel of our applications. So all our web pages inherit from this base
page so they don't have to worry about the look and feel and navigation, only
the main content. Everything has woked just fine until we converted to 2.0.
Now we have a problem with the new GridView and the paging. With the
DataGrid in 1.1, the paging worked just fine. Now with paging...

hi,
for an event handling mechanism,
we need an event object. (the object where the event actually occur)
and we need an event handler,
and we need a registration of the event handler to the event object(generator)
in java, we can create a generator class by extending EventObject class.
we can create an event handler class by implementing EventListener interface.
for registration we can provide some registration method (e.g...

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...

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...

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...
