I fixed it in the test application, effectively validating the solution I was planning on using, but hadn't actually implemented it.Once I tried to I realized why I did things the way I did originally: The data that is used in the unbound column is a read-only collection of objects and in order to set them I need to call a separate method on the object. Well, read only properties of course can't be edited in the DGV so I was dead in the water.Windows 98, Windows 2000 SP4, Windows Millennium Edition, Windows Server 2003, Windows XP Media Center Edition, Windows XP Professional x64 Edition, Windows XP SP2, Windows XP Starter Edition開発プラットフォームの中には、.
I have finally tracked down a bug that I've been working on for the entire weekend, however I don't see a way to really solve it - in a clean way, that is.
This made me go BACK to my original design and while researching I stumbled on this column/blog by Brian Noyes.
He mentions the event Rows Added and that's all I needed!
I can check to see that there is an issue, and throw the appropriate error message if there is.
The problem is being unable to cancel the moving from row to row (and, as such, attempting to save the changes).
