I have a situation where I have to dynamically add controls at runtime.
I am not sure how to deal with postback and retaining values in
textboxes. I have seen examples where you have to include properties
with the same name in the C# codebehind class. But this defeats the use
of dynamic controls. Is there anyway to access and maintain the values
in the fields?

I have a form that has a listbox on the top that is bound to a header table.
When the page first loads, it paints the adjacent textboxes with data from
the details table. However, when I postback the page with a new selected
from the header table, the textboxes is not loaded with the new details.
During DEBUG, I could actually see the values as it loops through the fields
but it never paints the details into the textboxes after the page is...

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...

I have created several grids dynamically and have added them to different
HTML placeholders on a vb.net web form. The grids and controls within them
come up and view beautifully when the web page first starts, but when I
click on a button, and the page comes back, my dynamically created grid and
controls are not visible. Any thoughts? Please view my sample code below.
If Not ispostback then

hi,
i have an aspx page which dynamically loads a user control and adds it
to a placeholder. the control is recreated and added to the
placeholder for postbacks as well.
the user control contains a datagrid and some buttons and textboxes.
the button events fire correctly and execute their code. however, the
datagrid events fire a postback, and execute Page_load in the
usercontrol, but the Item_Command code is not executed. the code to...

I have a page with a significant number of dynamically created radio
buttons, checkboxes and textboxes.
When a user is presented with this form and subsequently fills a bunch of
stuff out, when they click submit I want to save their postback data (i.e.,
which checkboxes are checked, which radio buttons are pushed and what's
typed into the textboxes).
Then later I want another user to be able to view one of these forms and
elect to...

I have a WebForm where I'm dynamically creating some controls and I'm having
difficulty understanding how the state is being persisted and how to work
with it.
I've created a simplified example to demonstrate my issues. Lets say I have
a WebForm with a DropDownList where the user selects a number from 1 to 10
(the DropDownList is not dynamically created). I also have a button on there
that I use to trigger a PostBack.

I'm dynamically creating all the Columns in a GridView at run time and
binding it to a DataTable. I have to build it at runtime (using an
ITemplate subclass) because the number of columns is based on User
input. All column cells are rendered as Textboxes. All Textboxs & the
Grid have EnableViewState = True;
Everything works fine except on Postback I can't seem to find the
embeded Textbox controls that are needed to determine what the...

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

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...
