Hello,

I have been looking into your question and you can set ‘ColumnSelection’ to “Single” like :

            <ig:XamGrid.SelectionSettings>

                <ig:SelectionSettings  ColumnSelection="Single"/>

            </ig:XamGrid.SelectionSettings>

and can handle the ‘SelectedColumnsCollectionChanged’ event like :

private void xamGrid1_SelectedColumnsCollectionChanged(object sender, SelectionCollectionChangedEventArgs<SelectedColumnsCollection> e)

        {

            string selectedColumnName = e.NewSelectedItems[0].Key;

        }

This event is fired only if you click on header cell.

Let me know, if you need any further assistance on this matter.
