Turn AdvStringGrid sort off

I have implemented sorting in my grid by clicking on a column header. It sorts fine and reverses correctly when clicking on column header again, it's all good. So how do I turn OFF sorting and remove the up/down glyph that is in the column header? I have cases in my app where users can have the grid do the sorting or they can have an external file that specifies the order. In that case I need to turn off all the grid sorting which includes the up/down glyph. Can't figure that one out.

Thanks for any help!

Did you try to set
grid.SortSettings.Show = false

Apparently I hadn't tried that yet as it worked.

Thank you Bruno!
