crdbgrid1.columns.delete(i) doesn't working

[mariusz]

I’ve code (like below). On standard dbgrid this procedure working, but here not. Procedure finding expedient column, but doesn’t delete this.

for i := 0 to crdbgrid1.Columns.Count -1 do
if lowercase(crdbgrid1.Columns.Items.Field.FullName) = 'highlight' then begin
showmessage('jest');
crdbgrid1.Columns.Delete(i);
end;

have anyone any idea what to do?

Deleting a column has an effect only if columns were created in the Columns Editor. Open the Columns Editor and press the Add All Fields button.

Ok. Thx.
I'll solve my problem by Unpluging crdbgrid, then add required columns to grid and then connect grid to query!
