Table Views provide the capability to automatically calculate and apply the optimal width required for a column to completely display its contents. The Best Fit feature can be applied to an individual column or to all columns displayed within a TreeList View. To enable this feature for all visible columns or individual columns, use the AllowBestFit and ColumnBase.AllowBestFit properties, respectively.
To resize the specified column to the optimal width required to display its contents completely, use the BestFitColumn method. To resize all columns, use the BestFitColumns method. End-users can resize columns to their optimal width (if allowed) by double clicking their right border or using the column header context menu.
