I created a web page which contains a form which contains a table. The
number of rows for the table are determined dynamically. The first cell of
each row contains a HyperLink control and the last cell contains a CheckBox
control. In order for the ViewState mechanism to work correctly, I:
1. create the structure (add rows/columns) of the table in the OnInit
handler when it is a PostBack,
2. create the table structure and populate its...

Dear ASP.NET Programmers,
I have a HTML table (running as server control with the control ID:
tblInsertSP). The table has 16 rows with textboxes. Depending on the value
of the ddlSPType, which is a dropdownlist control on the page, I add
dynamically extra rows to the table. For instance, if the ddlSPType selected
item is Aviation Company, an extra row containing a cell with the textbox
control txtAircrafts is added to the HTML table...

Hi,
I added a few link buttons in a function (loadControls) that is called only
on the first time the page is loaded. On the postBack I don't call this
function and want to retrieve the values of those controls (linkButtons). But
the only time I can see the values is if call the (loadControls ) on postBack
too.
How can I get the values of the controls without calling the 'loadControls'
function.

Hi there
Here is the situation - a table is built dynamically with values in the cells I need to retrieve and enter into a database. I have found a way of getting values using JavaScript, but of course with the table being dynamic I have no idea how many rows it will contain. One way is using the TableID.rows.count and then building if statements based on the value - but that is going to be an awfull lot of coding...... So the question is -...

I have a custom control that I wrote (I inherit from
System.Web.UI.WebControls.CompositeControl). I dynamically add this control
to my Page, but I was told that dynamically added controls do not survive
postback. This seems to be true. However, this seems to make dynamically
adding controls rather pointless to me, since if you cannot retrieve the
values of the controls when you perform a postback, why add the controls in
the firstplace?...

Hi
I have a datalist which loops through the categories and within the datalist I have a CheckBoxList which are bound on the DataList's OnItemDataBound.
The only problem I have is retrieving the values that have been checked when the user submits the form.
This code works as far as presentation goes but I can't seem to retrieve the checked values in the various checkboxlists that have been generated on the datalist's OnItemDataBound

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'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...
