Problem with Dropdown - ViewState and AutoPostBack

by: Lloyd Sheen | last post by:

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

The easy way to turn off automatic updates for Windows 10/11

by: Hystou | last post by:

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,...
