Parameters

topRow

Top row in the range.

leftCol

Left column in the range.

bottomRow

Bottom row in the range.

rightCol

Right column in the range.

extraSpace

Amount of extra space, in pixels, to add to the column widths.

flags

Flags that control auto-sizing options.

By default, the C1FlexGridBase.AutoSizeCols method measures every cell in each column, taking into account the cell contents and style.

If the grid has a large number of rows, you can improve performance by using the topRow and bottomRow parameters to specify a row range. You can include only a few hundred rows in the process, and add some extra spacing for safety.
