DataGridView.AutoResizeColumn Method (Int32, DataGridViewAutoSizeColumnMode, Boolean)

Adjusts the width of the specified column using the specified size mode, optionally calculating the width with the expectation that row heights will subsequently be adjusted.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

member AutoResizeColumn : 
        columnIndex:int * 
        autoSizeColumnMode:DataGridViewAutoSizeColumnMode * 
        fixedHeight:bool -> unit

Parameters

columnIndex
Type: System.Int32

The index of the column to resize.

autoSizeColumnMode
Type: System.Windows.Forms.DataGridViewAutoSizeColumnMode

One of the DataGridViewAutoSizeColumnMode values.

fixedHeight
Type: System.Boolean

true to calculate the new width based on the current row heights; false to calculate the width with the expectation that the row heights will also be adjusted.

ExceptionCondition
InvalidOperationException

autoSizeColumnMode has the value ColumnHeader and ColumnHeadersVisible is false.

ArgumentException

autoSizeColumnMode has the value NotSet, None, or Fill.

ArgumentOutOfRangeException

columnIndex is not in the valid range of 0 to the number of columns minus 1.

InvalidEnumArgumentException

autoSizeColumnMode is not a valid DataGridViewAutoSizeColumnMode value.

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.

This overload lets you specify a sizing mode that calculates the new width based on values in a limited set of cells, such as those in displayed rows only. This improves performance when the control contains a large number of rows.

This overload is protected and is designed to enable you to achieve ideal cell height-to-width ratios in a derived DataGridView class. If fixedHeight is false, the column width will be calculated with the expectation that you will call the AutoResizeRow or AutoResizeRows method next.

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