Grid

Description

This property is a 2-element Boolean value that specifies whether or not rows and columns may be added to a Grid object by the user.

If the first element of AutoExpand is 1, a row is added when the current cell is within the last row of the Grid and the user presses Cursor Down

Similarly, if the second element is 1, a column is added when the current cell is within the last column of the Grid and the user presses Cursor Right.

Note that when a row or column is added, the appropriate properties (including Values and CellTypes) are expanded accordingly.

The default value for AutoExpand is (0 0).

If AutoExpand is enabled, the Grid generates AddRow and AddCol events. You can return a zero from a callback function to selectively prevent the addition of rows and columns if appropriate.
