JL,
You can use the PropertyChanged event of the grid for this. You would just need to check the trigger of the event, such as:
private void ultraGrid1_PropertyChanged(object sender, Infragistics.Win.PropertyChangedEventArgs e)
{
if ((Infragistics.Win.UltraWinGrid.PropertyIds)e.ChangeInfo.Trigger.PropId == Infragistics.Win.UltraWinGrid.PropertyIds.ViewStyleBand)
{
// Do things with stuff
}
}
