Objective Grid: Requerying the recordset does not reflect changes in the row count

Problem

 

---

After I requery the recordset the grid does not reflect any changes in the row count, it even crashes sometimes.

This can happen when you call CRecordset::Requery() directly.

ACTION:

It is very important that you have to call Requery() for the grid and not for the recordset.

Example:

	void CMyRecordView::OnRecordRequery() {
		BOOL bLock = LockUpdate(); SetTopRow(1); MoveCurrentCell(GX_TOPLEFT); Requery(); LockUpdate(bLock); Redraw();
	}
