In VS2008, if you have disabled 'Auto ID elements on Paste in Source View', if you then copy and paste a control or group of controls, you get the annoying Error List window popping up telling you:
Generation of designer file failed: The ID 'someID' is already used by another control.
I realize under:
Tools, Options, Text Editor, HTML, Validation you can disable Show Errors to stop this, and then you will still be notified of this problem if you manually open the error list, but that option seems to disable a whole schwack of other things that I think one may want to be notified of.
Is it possible to keep the validation enabled, but just stop the automatic popping up of the error list? When I want to see errors, I can do a CTRL+\E thank you very much.
