DBGrid und Touchscreen

[GHorn]

Einfach beide Richtungen abfragen:

Delphi-Quellcode:

   DBGrid.DataSource.DataSet.DisableControls;
   // BOF:
   DBGrid.DataSource.DataSet.Prior;
   Btn_UP.Enabled := (NOT DBGrid.DataSource.DataSet.BOF);
   DBGrid.DataSource.DataSet.Next; 
   // EOF:
   DBGrid.DataSource.DataSet.Next; 
   Btn_Down.Enabled := (NOT DBGrid.DataSource.DataSet.EOF);
   DBGrid.DataSource.DataSet.Prior;
   DBGrid.DataSource.DataSet.EnableControls;
