Hello,

 

What's the best way to do this?

- loop ?

- delete column & recreate it

- hidden procedure I have not seen

 

Regards

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.

And does it work now?

Hello,

 

Can you please tell me what you mean. I still suggest a single loop for this operation.
