Talk:FMX.Grid.TColumn.CellControlByRow
Please document that this method was made protected in XE3. Code from earlier versions that used CellControlByRow should instead access the Grid Cell values directly, as illustrated in the TGrid samples here [1]
NOTE: CellControlByRow was not reliable as not all cells were backed by a physical control (doing so would require too much resources). IOW CellControlByRow could easily return nil.
