Oftentimes, when mapping domain values, the values set will randomly and inexplicably change while scrolling through the options.
Most often it can be seen from the source side but is visible on the target side as well.
If source is laid out as
1
2
3
4
After scrolling up and down the list of domain values WITHOUT changing anything on the source side, it sometimes could become something like
1
2
2
4
Without the user making a direct change.
Fixed. The problem was the Method11 data grid had the property ScrollViewer.CanContentScroll set to True. This broke the evaluation the underlying event handler did.
