Hi,
I'm trying to support IDataErrorInfo. I found a blog post that shows how to mark a cell as invalid using the on EditModeEnded event. The problem I'm now having is that an item in the grid can become invalid due to other changes made in other rows. When this happens, a PropertyChanged event is raised on the .Net object which acts as the DataItem for the row, but I'm not sure how to respond to mark the cell as invalid.
Is there an event I can use to acomplish this?
Thanks
I looked at the sample provided in the thread below. While I'm sure it works, it looks like a lot of work to me, especially when my domin objects already support validation via IDataError. I haven't had the motivation to implement a second, duplicate valiaditon mechanism just for the grid.
It would be great if Infragistics would implement support for this standard validation mechanism.

It's becoming more work that it's worth.. I think I may try the xceed grid. I think this grid is more for showing data than editing it.
I agree - the grid is great for shoing data, especially multi-tiered data, but I'm not a fan of using it for inline editing. It seems like I'm using 5% of its functionality ... like maybe I should be using a customized list view for much of this?
