The CExtGridCell::OnClick() virtual method has the constant CExtGridHitTestInfo & htInfo parameter that completely describes the location of the cell being clicked and even which part of the cell is hovered by the mouse pointer (check box, button, text area and etc). You need to use htInfo.m_nColNo and htInfo.m_nRowNo as cell coordinates.
