I have a page that uses an in-place editable DataGrid that supports sorting and paging. EnableViewState is turned ON. At the top of the page are several search fields that allow the user to filter the results in the grid.
Say you filter the grid for records that have a certain condition set to "NO" (in this case a checkbox). In this scenario the search returns one result. If I then check the checkbox ("YES") and save it, I now get my message...

Hi
I have a aspx-page with a panel-control. On this panel control I add user
controls dynamicly with LoadControl and panel.Controls.Add(myControl).
On some of the dynamicly added user controls I have button's and handlers

Why doesn't the event get fired in the dynamicly added control?
Thanks!

I. Failed to load viewstate. The control tree into which
viewstate is being loaded must match the control tree that was used to save
viewstate during the previous request. For example, when adding controls
dynamically, the controls added during a post-back must match the type and
position of the controls added during the initial request.

Hello,
I have a problem in ASP.NET 2.0 with the viewstate of my dynamically
added user control. I have reproduced the problem with a very simple
user control and a very simple page.
On my usercontrol is a button and a label. Everytime the button is
clicked a counter which is stored in the viewstate is increased and
displayed in the label.

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

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,...
