HI,

 You can wire up the  Field's PropertyChanged Event.

 then inside the event  check out the e.propertyname field.

xamDataGrid1.FieldLayouts[0].Fields[0].PropertyChanged +=

new PropertyChangedEventHandler
(MainWindow_PropertyChanged);

void MainWindow_PropertyChanged(object sender, PropertyChangedEventArgs e)

{

//throw new NotImplementedException();

MessageBox
.Show(e.PropertyName);

 You will see LabelWithResolved and CellWidthRsolved names.

 Down side is this might fire often.

 Sincerely.
