member AutoResizeColumn : 
        columnIndex:int -> unit

Parameters

Type: System.Int32

This method is useful if you want to control when a column resizes. The column width is adjusted only once per method call; if the contents of the column later change, the column will not automatically adjust. To resize all columns, use the AutoResizeColumns method. To set the column to automatically resize whenever its contents change, use the AutoSizeColumnsMode property or the column AutoSizeMode property.

For more information about programmatic resizing, see Sizing Options in the Windows Forms DataGridView Control.

The following code example uses this method to make the column width large enough to accommodate a new cell value. This example is part of a larger example available in How to: Manipulate Rows in the Windows Forms DataGridView Control.
