DataGridView.AutoResizeRows Method (DataGridViewAutoSizeRowsMode)

Adjusts the heights of the rows using the specified size mode value.

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

public void AutoResizeRows(
	DataGridViewAutoSizeRowsMode autoSizeRowsMode
)

Parameters

autoSizeRowsMode
Type: System.Windows.Forms.DataGridViewAutoSizeRowsMode
One of the DataGridViewAutoSizeRowsMode values.

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.

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

The following code example demonstrates how to resize all rows based on non-header cell content. This code example is part of a larger example provided in How to: Programmatically Resize Cells to Fit Content in the Windows Forms DataGridView Control.


private void SizeAllRows(Object sender,
    EventArgs e)
{
    dataGridView1.AutoResizeRows(
        DataGridViewAutoSizeRowsMode.AllCellsExceptHeaders);
}
