When you attempt to delete a site column that is still included in a site content type (but you didn't know that ahead of time) you get an ugly unhandled exception dialog with two choices:
It is not clear if it is safe to Continue.
Wouldn't it be preferred to catch the exception and display a friendly dialog along the lines of:
- SharePoint Manager was unable to delete this site column. The following error was returned:
- Site columns which are included in content types or on lists cannot be deleted. Please remove all instances of this site column prior to deleting it.
Then I would have some confidence that it is safe to continue and proceed to remove the site column from any content types or lists before re-attempting to delete it.
