I am having a terrible time getting anything useful out of a listbox
on my web form.
I am populating it with the results from Postcode lookup software, and
it is showing the results fine. What I want to do is to allow the
user to click on the row that corresponds to the correct address, and
have the code behind populate the form's Address1, Address2 etc.
controls with the relevant data items.
I put the code for this into the...

I have two listboxes, the first of which is an autopostback=true that allows
multiple row selection. When I select multiple values (by holding down CTL)
in the first one, it should query the second one. I seem unable to do this
as it only sends back the first item I select whether I have the CTL key
down or not. Upon the return trip, I can select another one, but it still
only sends value for the last one I selected.

Hi,
I open up a webform (vb.net) and populate a listbox
control on the Page load event. If I click on (select)
and item from the listbox I want to write the value of the
selected item to a label control. Nothing happens. But
when I click a button (which contains same code to write
to label) I get the value of the selected item in the
Label.

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...

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,...
