DevExpress, GridControl, how the Best Fit Column feature works

The property GridView.BestFitMaxRowCount indicates how many rows will be processed in order to adjust the best column width.

• -1 means that all row will be processed
• 0 nothing
• Any other value indicates how many will be processed

For performance issues apply a small number or apply 0.

Important note: If auto width is enabled, a column's GridColumn.Width property doesn't contain its visible width, but the value used when auto width is false, so that a column's layout can be restored. A column's visible width is available via its GridColumn.VisibleWidth property.
