To resize Grid rows and columns, you need non-scrolling cells (gray, reliefed cells which always remain visible in the leftmost column(s) and topmost row(s) while ordinary cells are scrolled in and out of sight):

Columns are resized by dragging the vertical boundaries between non-scrolling cells in the topmost row(s).
Rows are resized by dragging the horizontal boundaries between non-scrolling cells in the leftmost column(s).
The Grid object always provides a non-scrolling "header" cell for each record field. If orientation is rowwise (columnwise), you are therefore guaranteed to have a non-scrolling top row (left column). To also have a non-scrolling top row (left column) the record definition must define at least one fixed field; also, fixed fields must be enabled.
