Hello,

 

What's the best way to do this?

- loop ?

- delete column & recreate it

- hidden procedure I have not seen

Hello Boki,

 

In fact, I try to deal with delete a recreate the column.

 

But I experience malfunction as, using this code:

gridWagonSet.Columns.Delete(0);
gridWagonSet.Columns.Insert(TNxCheckBoxColumn,0);
with gridWagonSet.Columns[0] do begin
     Alignment:=taCenter;
     Width:=25;
end;

the column is in 2nd position in the grid and I need to add "Position:=0;"  in the with statement

 

Looking at the TNxColumns.InsertColumn procedure, : (called from TNxColumns.Insert function)

FItemsList.Insert(Pos, Column);
FPositionItemsList.Add(Column);

Shouldn't you insert (not Add) into the 2nd TList ?

Hi,

 

I think the best solution is just to loop trough all cells in the column and set values to false. Deleting and inserting column again is probably slower.
