DataGridView.AutoResizeRow Method (Int32, DataGridViewAutoSizeRowMode, Boolean)

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

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

protected void AutoResizeRow (
	int rowIndex,
	DataGridViewAutoSizeRowMode autoSizeRowMode,
	bool fixedWidth
protected void AutoResizeRow (
	int rowIndex, 
	DataGridViewAutoSizeRowMode autoSizeRowMode, 
	boolean fixedWidth
protected function AutoResizeRow (
	rowIndex : int, 
	autoSizeRowMode : DataGridViewAutoSizeRowMode, 
	fixedWidth : boolean
Not applicable.



The index of the row to resize.


One of the DataGridViewAutoSizeRowMode values.


true to calculate the new height based on the current width of the columns; false to calculate the height with the expectation that the column widths will also be adjusted.

Exception typeCondition


autoSizeRowMode has the value RowHeader and RowHeadersVisible is false.


autoSizeRowMode is not a valid DataGridViewAutoSizeRowMode value.


rowIndex is not in the valid range of 0 to the number of rows minus 1.

This method is useful if you want to control when a row resizes. The row height is adjusted only once per method call; if the contents of the row later change, the row will not automatically adjust. To resize all rows, use the AutoResizeRows method. To set the row to automatically resize whenever its contents change, use the AutoSizeRowsMode property.

For cell contents to wrap onto multiple lines when a row is resized, the cell style in effect for the cell must have a WrapMode property value of True.

This overload lets you specify a sizing mode that calculates the new height 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 fixedWidth is false, the row height will be calculated with the expectation that you will call the AutoResizeColumn or AutoResizeColumns method next.
