Get column index by Column header in WPF DataGrid

问题

How to get the Column index or Column.DisplayIndex from its Column Header in WPF DataGrid?

I know the Column Header, want to get column index.

回答1:

you could use DisplayIndex (be aware this will change if columns are resorted)

var index = dataGrid.Columns.Single(c => c.Header.ToString() == "HeaderName").DisplayIndex;
