フィールドの移動時に CellValuePresenterStyle を設定すると、正しく更新されるはずです。次のロジックがこれを行います。
void XamDataGrid1_FieldPositionChanged(object sender, Infragistics.Windows.DataPresenter.Events.FieldPositionChangedEventArgs e)
{
FieldLayout layout = e.Field.Owner;
Field first = null;
foreach (Field f in layout.Fields)
{
if (f.ActualPosition.Column == 0)
first = f;
}
if (first != null)
{
SetCellValuePresenterStyle(e.Field.Owner, first);
}
}
void XamDataGrid1_FieldLayoutInitialized(object sender, Infragistics.Windows.DataPresenter.Events.FieldLayoutInitializedEventArgs e)
{
SetCellValuePresenterStyle(e.FieldLayout, e.FieldLayout.Fields[0]);
}
void SetCellValuePresenterStyle(FieldLayout layout, Field sourceField)
{
Binding sourceValueBinding = new Binding("DataItem[" + sourceField.Name + "]");
foreach (Field f in layout.Fields)
{
if (f != sourceField)
{
Style cellValuePresenterStyle = new Style(typeof(CellValuePresenter));
Binding compareValueBinding = new Binding("DataItem[" + f.Name + "]");
MultiBinding styleBinding = new MultiBinding();
styleBinding.Bindings.Add(sourceValueBinding);
styleBinding.Bindings.Add(compareValueBinding);
styleBinding.Converter = new EqualMultiValueConverter();
DataTrigger trigger = new DataTrigger();
trigger.Value = true;
trigger.Binding = styleBinding;
cellValuePresenterStyle.Triggers.Add(trigger);
Setter backgroundSetter = new Setter(Control.BackgroundProperty, Brushes.Green);
trigger.Setters.Add(backgroundSetter);
f.Settings.CellValuePresenterStyle = cellValuePresenterStyle;
}
else
{
f.Settings.CellValuePresenterStyle = null;
}
}
}
