here is the problem, I have a table with dynamic buttons and events.
On buton click of said row, it would clear the rows in the table, and
repopulate it.
This works fine the first time you run the app on the first click.
Every other attempt to click one of these buttons fires a page load only,
upon the 2nd click a button click event is fired. This was verified by
adding a list box to the page, in Page_Load and Button_Click event adding
code to add an item to the listbox denoting which method was called.
When clicking the buttons, I see Page_Load, clicking a second time I see
Page_Load, Button_Click as I would expect (and how it works the very first
time the page is clicked). 2 1416
If your buttons are dynamically created then their events
(assigning the event handler) and buttons have to be
recreated on every postback.

Besides what Suresh mentioned, you also have to be sure that the identifiers
of the dynamically created controls are the same when they're first created
and when they're re-created from Page_Load to restore state.
In your case I'm almost sure you have to assign the identifiers yourself,
because with the automatic identifier assignment, I think the identifiers
won't be the same in the two mentioned cases.
If you're already assigning identifiers yourself, then it's good to
check by debugging whether the identifiers are constant.

Hi all and thanks in advance,
I am stuck! I can't figure out how to identify which button was clicked on my ASP.NET page in the PostBack event? So what I am trying to do is to is to have an if statement like as follows in the PageLoad:
private void Page_Load(object sender, System.EventArgs e) {
if (!Page.IsPostBack) {
//do something here
} else {

A couple of easy questions here hopefully. I've been working on two
different database projects which make use of multiple
forms.
1. Where's the best/recommended placement for command buttons for things
like delete, save, edit, cancel buttons - in the footer, or on the form
detail section?
2. If in the footer, how do you add them to the tab order?

I'm working with VWD and i defined programmatically a button (in

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,...
