OK, here's another question for the experts:
I am building a multi-step (3 steps actually) form using a panel for
each step and hiding/displaying the appropriate panel/panels depending
on which step you're on. This all works fine, but I ran into some
trouble when I started creating controls dynamically in my code-behind
file.
Each panel contains a table which is filled with various radio buttons,
text fields and the such which are...

Hi all,
I need finality on this once and for all please.
I have a main page which contains a couple of placeholders and within these
placeholders, depending on what the user presses, I load different user
controls. This loading of user controls is done within the code-behind of
the main page. The problem is that before loading a user control in place of
another, I need to do a Controls.Add then a Controls.Remove so the viewstate
is...

Hi all,
Here's a problem I'm having with a dynamic table. Following the
guidelines here
(http://www.codeproject.com/aspnet/dynamiccontrols.asp), which make
perfect sense. The problem is that the table contains a SELECT box
populated on the initial load. Every time I postback I'm inserting a
column into the table, the dropdown always remains in the last column.
First time I postback the dropdown is populated okay. The second time...

Anyone up for a challenge?
I've been struggling with this for a few days and was hoping someone could
help me. Pouring through all the messageboards I just can't find the
solution.
We have a GridView that needs to be dynamically designed, depending on what
collection of fields our uses want to edit for their product data. We have
400+ fields of information per product so they're selecting a subset of those
fields to edit.

Hi,
In ASP.net 2.0 I make a control which add the same controls dynamically. In
the oninit event I add the controls to the controls collection. After that
the loadviewstate event fills in the information on postbacks. The control
can add and delete controls that is why on the postback I don't know how many
controls there are.
At the moment I am able to get the controls rendering but I have problems to
save the count of the dynamic...

Hi there
The problem of dynamically created controls vs viewstate is widely
known one. To access values of controls they have to be recreated on
Page_Load.
Unfortunately it causes many problems in the following (rather common,
I guess) scenario:
The controls are created dynamically. Their number and contents

I always thought that the viewstate "keys" included the control ID. As long
as the control IDs were unique, there shouldn't be any conflicts. Well, it
appears that that may not be the case with dynamic controls. Our application
was having a problem very similar to the one described here:

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...
