Programming Hints / UniDBGrid correct RecNo

[mapper]

Like you know, The Database dont return correct RecNo properties everytime.

Perhaps, you must scrool all data. (with Prior, next).

 

I found a way;

 

1- Creat a new UniDBGrid field for first column. (like NO)

 

2- Copy-paste this code to  DrawColumnCell event :

 

procedure ....Form.UniDBGrid1DrawColumnCell(Sender: TObject; const Rect: TRect;

  DataCol: Integer; Column: TColumn; State: TGridDrawState);

 

var

  vDbGrid: TDBGrid absolute Sender;

 

begin

 

  // only do the next line if this event generated for

  // the first columnn (column with index 0)

  if DataCol=0 then

    vDbGrid.Canvas.TextOut(Rect.Left + 2

                           , Rect.Top + 2

                           , IntToStr(vDbGrid.DataSource.DataSet.RecNo));

 

end;

 

 

Good programming..

function reconfigure(sender, store, columns, oldStore, the, eOpts)
{
  sender.headerCt.insert(0,new Ext.grid.RowNumberer({text:'',width:'auto',align:'center',menuDisabled:false}));
}

This will not be correct if I do sorting in client-side !!
