For example, if a column is hidden after it is automatically sized to fit a large cell value, the hidden column will not change its size if the row containing the large cell value is deleted.

Content-based automatic sizing modes do not affect rows, columns, or headers that you have hidden by setting the row or column Visible property or the control Row Headers Visible or Column Headers Visible properties to false.

To avoid performance penalties, use the automatic sizing modes that calculate sizes based only on the displayed rows rather than analyzing every row in the control.

If content-based automatic sizing is enabled for one dimension only—that is, for rows but not columns, or for columns but not rows—and Wrap Mode is also enabled, size adjustment also occurs whenever the other dimension changes.

In this case, call the Update Cell Value method to force the control to update the cell display and apply the current automatic sizing modes.

With these values, you can limit which cells are used to calculate the preferred sizes.

The enumerations used by sizing properties and methods have similar values for content-based sizing.
