I have an Xceed DataGridControl whose ItemsSource property is a System.Data.DataTable. One column is a “start date” and another is an “end date” (there are other columns as well). I’ve written CellValidationRules for the columns that check that the start date comes before the end date. They work fine except when both dates are edited before either is committed. In that case, I would like the validation rule to validate the edited start date against the edited end date (not the committed end date). Is there a way to do that? A code snippet would be great.
