Data Grid - Hide Columns

[Stuart_Kelly]

Hi, I am testing the TTMSFNCDataGrid visual grouping features in Rad Studio 13.

Can you create a hidden column, which could stores a database ID? Using the standard stringgrid, I can set the ColWidths to -1

Thanks Stuart

Hi,

You can call HideColumn(X) where X is the index of the column you want to hide.

Thanks Pieter, that works initially but after I drag columns into the visual grouping header, they appear.

In the example below the MenuID and TypeID columns are hidden at the start.

Hi,

To work around this you can implement 2 events:

procedure TForm1.TMSFNCDataGrid1AfterCloseHeaderGroup(Sender: TObject;
AColumn: Integer);
begin
  TMSFNCDataGrid1.HideColumn(8);
  TMSFNCDataGrid1.HideColumn(9);
end;

procedure TForm1.TMSFNCDataGrid1AfterDropHeaderGroup(Sender: TObject;
AColumn: Integer);
begin
  TMSFNCDataGrid1.HideColumn(8);
  TMSFNCDataGrid1.HideColumn(9);
end;

We’ll write this down and see what can be done to improve this.

Thanks Pieter, thanks that works.

Yeah, it would be nice if there was a option to permanently hide a column...

Thanks, Stuart
