If cell values are taken into account when calculating a column's optimal width, you can specify the way this width is calculated. A column's width is calculated based on all cells' text within this column by default.
You can increase the application's performance by limiting the number of records taken into account when calculating the optimal width. This property is set to -1 by default to indicate that all cells are processed. If the property is set to a positive value, a View processes the specified number of cells starting from the top visible cell.
