My XamDataGrid has 3 fields(No, Action, ActionInfo). WhenInfo field has 5byte data. so, the data means time(HH:mm) or datetime(yy/MM/dd HH:mm) or custom data.

so, i am using datatrigger.

                <Style x:Key="ActionInfoCellValueEditorStyle" TargetType="{x:Type igEditors:XamTextEditor}">
                    <Style.Triggers>
                        <DataTrigger Binding="{Binding Path=Cells[Action].Value}" Value="255">

however, my code has a problem. first time, when i edit Action field, ActionInfo is displayed by data trigger. but, when i edit Action field after i edit ActionInfo field, ActionInfo filed is displayed by old data. but, after XamDataGrid was redraw by grouping, ActionInfo field is displayed by new data.

How can i modify my code??
