I keep getting an exception when I call the DataAdapter Update method.

Hi folks,
A bizarre problem I am having.

XMLDataSource.Data property is set to the result of a function that
generates an XML document from a SQL Query. The problem is that the
Treeview renders correctly and expands with the appropriate hierarchy
but clicking anything but the very top node gives me a NULL Reference
Exception. I haven't even got to the stage of doing anything...

the user control it will give a null reference exception when you wrap that
in an update panel.

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,...
