Use the SelectCell method to select a cell, adding it to the existing selection (if any). A cell is located at the intersection of the specified node and column.
The SelectCell method does nothing if the DataViewBase.NavigationStyle property isn't set to GridViewNavigationStyle.Cell and/or the MultiSelectMode property isn't set to TableViewSelectMode.Cell.
To select multiple cells, use the SelectCells method.
To learn more on multi-cell selection, see Multiple Cell Selection.
