Programmatic resizing is useful to avoid performance penalties with continuous resizing.

When you programmatically resize columns that have Inherited Auto Size Mode property values of Fill, however, the calculated content-based widths are used to proportionally adjust the column Fill Weight property values, and the actually column widths are then calculated according to these new proportions so that all columns fill the available display area of the control.

The new sizes are automatically calculated to display all cell contents without clipping.

When automatic sizing is disabled, you can programmatically set the exact width or height of rows, columns, or headers through the following properties: These methods will resize rows, columns, or headers once rather than configuring them for continuous resizing.

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.

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.

For maximum performance, use programmatic resizing instead so that you can resize at specific times, such as immediately after new data is loaded.

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.
