DataGridView.AutoResizeColumns Method (DataGridViewAutoSizeColumnsMode, Boolean)

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

protected void AutoResizeColumns (
	DataGridViewAutoSizeColumnsMode autoSizeColumnsMode,
	bool fixedHeight
)

Parameters

autoSizeColumnsMode

One of the DataGridViewAutoSizeColumnsMode values.

fixedHeight

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

Exception typeCondition

InvalidOperationException

autoSizeColumnsMode has the value ColumnHeader and ColumnHeadersVisible is false.

ArgumentException

autoSizeColumnsMode has the value None or Fill.

InvalidEnumArgumentException

autoSizeColumnsMode is not a valid DataGridViewAutoSizeColumnsMode value.

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

This overload lets you specify a sizing mode that calculates the new widths 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 widths will be calculated with the expectation that you will call the AutoResizeRow or AutoResizeRows method next.
