DataGridView.AutoResizeRow Method (Int32, DataGridViewAutoSizeRowMode)

Adjusts the height of the specified row using the specified size mode.

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

public void AutoResizeRow(
	int rowIndex,
	DataGridViewAutoSizeRowMode autoSizeRowMode
)

Parameters

rowIndex
Type: System.Int32

The index of the row to resize.

autoSizeRowMode
Type: System.Windows.Forms.DataGridViewAutoSizeRowMode

One of the DataGridViewAutoSizeRowMode values.

ExceptionCondition
InvalidOperationException

autoSizeRowMode has the value RowHeader and RowHeadersVisible is false.

InvalidEnumArgumentException

autoSizeRowMode is not a valid DataGridViewAutoSizeRowMode value.

ArgumentOutOfRangeException

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.

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

The following code example resizes the third row in a DataGridView to fit the column contents. 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 SizeThirdRow(Object sender, EventArgs e)
{
    dataGridView1.AutoResizeRow(
        2, DataGridViewAutoSizeRowMode.AllCellsExceptHeader);
}
