DataGridView.AutoResizeRows Method (DataGridViewAutoSizeRowsMode, Boolean)

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

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

protected void AutoResizeRows(
	DataGridViewAutoSizeRowsMode autoSizeRowsMode,
	bool fixedWidth
)

Parameters

autoSizeRowsMode
Type: System.Windows.Forms.DataGridViewAutoSizeRowsMode
One of the DataGridViewAutoSizeRowsMode values.
fixedWidth
Type: System.Boolean
true to calculate the new heights based on the current column widths; false to calculate the heights with the expectation that the column widths will also be adjusted.

ExceptionCondition
InvalidOperationException

autoSizeRowsMode has the value AllHeaders or DisplayedHeaders, and RowHeadersVisible is false.

InvalidEnumArgumentException

autoSizeRowsMode is not a valid DataGridViewAutoSizeRowsMode value.

ArgumentException

autoSizeRowsMode has the value None.

This method is useful if you want to control when rows resize. The row heights are adjusted only once per method call; if the contents of the rows later change, the rows will not automatically adjust. To resize a specific row, use the AutoResizeRow method. To resize a subset of rows, use the AutoResizeRows(Int32, Int32, DataGridViewAutoSizeRowMode, Boolean) overload. To set the rows to automatically resize whenever their 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 heights 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 the fixedWidth parameter is false, the row heights will be calculated with the expectation that you will call the AutoResizeColumn or AutoResizeColumns method next.
