Counting the rows in a TDbGrid

Question

I have a TDbGrid, and I can easily tell how many columns are in it at runtime with the FieldCount property, but there doesn't seem to be a corresponding RowCount property to display how many records are being displayed. How can I find this out?

Answer 1

Both RowCount and VisibleRowCount are protected properties in TCustomGrid that are not exposed in TDBGrid. But you can get round that doing the following:

type
  TDummyGrid = class(TDBGrid);

  RowCount := TDummyGrid(MyDBGrid).RowCount;
  VisibleRowCount := TDummyGrid(MyDBGrid).VisibleRowCount;

Be warned that this includes the header.
