Hello --
Is there a way to prevent the autopostback of a drop down list if there is a
"default" item in the list -- example, a drop down list where the first item
says "Select One" and the remaining items are all values available for
selection....if the user changes the selection I want to postback, unless
they are selecting the default item. Is there a way to do this using
autopostback? Or should I just use client side script and...

I have a page that works fine. I am trying to optimize the page by
overriding some of the Information that is being saved in the hidden
VIEWSTATE.
If I make the properties of the dropdown False for ViewState and True for
AutoPostBack, it does reload the page but does not call the
SelectedIndexChanged event. If I put the ViewState to True then it is
called.
Does this mean that I cannot get that event and deal with it in better code

why need to set autopostback property to be true?? I know autopostback event
means to send the form to the server automatically.
I tried checkbox, checkbox list, radio button, and radio button list, and
they all need to set autopostback property to be true, in order to make the
event of the control fires.
I know this is the must, but I dont know why. Please advise!
Thanks!

I have a grid with a select button. I went to turn off AutoPostBack and
there is no such attribute. Is there any way to make a grid behave as would
a listbox and not autopost back upon the selection?
Thanks,

I have a datagrid with checkboxes and I can check/uncheck the
checkboxes to update a database by calling my oncheckchanged function.
I would like to add popup asking the users if they are sure they want
to proceed.
I have written a javascript function named confirm_duplicate and it
works as expected - it checks/unchecks checkboxes depending on user
response.

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,...
