I'm developing a Web application where a user selects from a listbox which can have many items. The initial display only shows about 10 items.
After a postback, the listbox is automatically scrolled back to the top, so the selected item is mostly no longer visible. How can I keep the position, so that the selected item is still shown?

I have created a Web Custom Control that inherits from
WebControls.ListBox but can't get it to retain the selectedIndex after
a postback. As a test I created a very simple version of the control
with no additional code. I just inherited from the exisiting ListBox
class and put the control on a page.
I put this control a blank page along with a button to perform a post
back. I select an item in the list box and then click the button...

I have a ListBox webcontrol on an aspx page. Items are added to the
ListBox using client-side code. However, when the page is posted back the
items are missing/not available. (It is like the page does not know the
items were added client-side.)
TIA,

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...

Hello all:
Clearly, I'm not getting it! Here is the scenario:
On a web page, I have two list boxen and a text box. The first listbox
is populated at page load time (if it is not a postback). This listbox
has AutoPostback = True. When the user selects an item from this list,
the second listbox is populated with more items relevant to this
selection. I am using an SQLDataSource web control for this. These
items are headers. I want, when...

Hi,
How can I capture the vertical scroll bar position for a Listbox.
I have a Listbox of 100 items + when I click on it I post back remove the
item selected.
After returning to the client browser the list box scroll position is at the
top.

Huh? Did you mean Listbox not DropDownList? The drop-down is working
fine, it's the Listbox data that gets cleared after the drop-down list
causes the postback.

I have a .net app that a user currently enters a number in a text box,
hits a button and a data call is executed. She wants the ability to
enter in multiple numbers (up to 100).
So to make things look better visually for that, I created a listbox
under the text box. She enters the number in the text box, clicks
another button I added and the number is stored in the list box. Then
my plan was to grab all those numbers from the list box...

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,...
