That's another trick (with a few more lines of code) :-))))

Do you know why i now can't sort the DataGrid by clicking the column header?
By default, users can sort the data in a DataGridView control by clicking
the header of a column.

Thank you very much !

I am more of a Web.UI.Control programmer rather that Windows.UI.Control
programmer. So, I don't know why the sort by column header doesn't work
for you.

You may have to do it manually if someone can't help you to make it work
automatically.

You can also consider this event.

ColumnHeaderMouseClick
This event is used to capture when a header is clicked.
Sometimes you may need to modify the direction that the
sort glyph is pointing in the column squares.
You can check e.ColumnIndex on the event parameter to
find out which of the column headers was clicked.

You might use this event, and based on e.ColumnIndex, query and sort 'q'
on corresponding property in the list of objects in 'q' and rebind.

If(e.ColumnIndex == 0)
{
var q1 = (from a in q.OrderBy(b => b.Name) select a).tolist();
// bind q1
}

If you want descending then q.OrderByDescending(b => b.Name).

Thank you for the explanation.

But it is weird that the default sort by clicking the header of a column
disappeared.
I've checked all settings again, but no result.
