will be helpful for those in need DisplayIndex is different from ColumnIndex. so when you change the DisplayIndex you are changing only the order of the column not the base index in its columns array.
actually you can't replace DataGridColumn Index, but if you insist you should clear DataGridColumns and re add them programmatically as you want. the big reason is that the DataGridColumn "Must" has belonged DataGrid parent.

should help you out You can extend ObservableCollection with some Linq or a foreach loop to do a linear search on the columns.
code :
public static class MyExtensions
{
    public static DataGridColumn GetByName(this ObservableCollection<DataGridColumn> col, string name)
    {
        return col.SingleOrDefault(p =>
            (string)p.GetValue(FrameworkElement.NameProperty) == name
        );
    }
}
myGrid.Columns.GetByName("theName");

seems to work fine Found a solution with a single line of code to pragmatically set the current cell based on the items and column index for anyone else who may be looking for a solution to this as well.
In the XAML ensure the SelectionUnit is set to cell. Then:
code :
dg.CurrentCell = new DataGridCellInfo(dg.Items[0],dg.Columns[0]);

it helps some times you could use DisplayIndex (be aware this will change if columns are resorted)
code :
var index = dataGrid.Columns.Single(c => c.Header.ToString() == "HeaderName").DisplayIndex;
