Get column index by column header in WPF DataGrid

Question

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

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

Answer 1

you can use DisplayIndex (remember that this will change when using columns)

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

Answer 2

It seems that "paul" has a little mistake. Here is my code:

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