Hi Croesusdev,

As far I can see you are looking for a way to freeze specific (the firs column ) and the others can fixed and moved freely without taking the first position. Based on this requirements I have modified Elizabeth’s sample in order hold the first filed always on first position by changing the FieldPositionChanged and FieldPositionChanging:

private void xamDataGrid1_FieldPositionChanged(object sender, Infragistics.Windows.DataPresenter.Events.FieldPositionChangedEventArgs e)
        {
           //3 Other columns can be fixed.
           // ensure that the first filed name will be always on first place
            if (e.Field.ActualPosition.Column == 0)
            {
                xamDataGrid1.FieldLayouts[0].Fields["name"].ActualPosition = new Infragistics.Windows.DataPresenter.FieldPosition(0, 0, 1, 1);
                xamDataGrid1.FieldLayouts[0].EnsureUniqueFieldPositions();
            }
        }
 
        private void xamDataGrid1_FieldPositionChanging(object sender, Infragistics.Windows.DataPresenter.Events.FieldPositionChangingEventArgs e)
        {
            //1 One particular column (let's call it A) must always remain the left-most column.
            //2 Other columns can be fixed.
 
            if (e.Field.Name == "name")
            {
                e.Cancel = true;
            }
        }
