You must then call the Auto Resize Columns method to adjust the column widths to the calculated ideal. For example, if you call the Auto Resize Rows(Data Grid View Auto Size Rows Mode, Boolean) overload of the Auto Resize Rows method and pass in a value of false for the Boolean parameter, the overload will calculate the ideal heights and widths for cells in the row, but it will adjust the row heights only. Use content-based automatic resizing with caution when working with large amounts of data. The value of this property is based on the column's Auto Size Mode property value unless that value is Not Set, in which case the control's Auto Size Columns Mode value is inherited. 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.

For example, if rows but not columns are configured for automatic sizing and Wrap Mode is enabled, users can drag column dividers to change the width of a column and row heights will automatically adjust so that cell contents are still fully displayed.

Note: If you maintain cell values in a custom data cache using virtual mode, automatic sizing occurs when the user edits a cell value but does not occur when you alter a cached value outside of a Cell Value Pushed event handler.

In this case, size adjustment occurs whenever cell contents change.

You will typically call the programmatic resizing methods at specific times.

It is also useful to provide initial sizes for user-resizable rows, columns, and headers, and for column fill mode.

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.
