I have a datagrid that is filtered via a DataView based upon a DateTimePicker value external to the grid. I also have a DateTimePicker column in the grid that allows editing. When I edit the date in the grid as soon as I move to another row the edited row automatically disappears since it no longer fulfills the RowFilter criteria. Is there some way to keep it from re-filtering the DataView until perhaps the Save button is clicked or another date from the external DateTimePicker is selected??
