例外

このプロパティの設定時に指定した値が、有効な DataGridViewRowHeadersWidthSizeMode 値ではありません。The specified value when setting this property is not a valid DataGridViewRowHeadersWidthSizeMode value.

主に表示用のDataGridViewコントロールでこのプロパティを使用する方法を次のコード例に示します。The following code example illustrates how to use this property in a DataGridView control intended primarily for display. この例では、コントロールの外観がいくつかの方法でカスタマイズされており、コントロールは対話機能を制限するように構成されています。In this example, the visual appearance of the control is customized in several ways and the control is configured for limited interactivity. この例は、 DataGridViewCellStyleクラスの概要で使用できるより大きな例の一部です。This example is part of a larger example available in the DataGridViewCellStyle class overview.

// Configures the appearance and behavior of a DataGridView control.
private void InitializeDataGridView()

    dataGridView1.Dock = DockStyle.Fill;
    dataGridView1.BackgroundColor = Color.LightGray;

    // limited interactivity.

    // value won't override DataGridView.DefaultCellStyle.SelectionBackColor.

注釈

このプロパティが自動サイズ変更モードに設定されている場合、ユーザーが行ヘッダーの幅を調整することはできません。When this property is set to an automatic sizing mode, the width of the row headers cannot be adjusted by the user.

プログラムによって行ヘッダーの高さを調整するにAutoResizeRowHeadersWidthは、メソッドをRowHeadersWidth使用するか、プロパティを設定します。To adjust the height of the row headers programmatically, use the AutoResizeRowHeadersWidth method or set the RowHeadersWidth property.

列ヘッダーのサイズ変更モードを設定するには、 ColumnHeadersHeightSizeModeプロパティを使用します。To set the sizing mode for the column headers, use the ColumnHeadersHeightSizeMode property.

ヘッダーのサイズ設定の詳細については、「 Windows フォーム DataGridView コントロールのサイズ変更オプション」を参照してください。For more information about header sizing, see Sizing Options in the Windows Forms DataGridView Control.

注意

コントロールDataGridViewは、ダブルバッファリングをサポートしていません。The DataGridView control does not support double buffering. 派生DoubleBuffered trueコントロールでがに設定されている場合、行、列、またはヘッダーのサイズを変更するときや、列を並べ替えるときに、ユーザーは視覚的なフィードバックを受け取りません。 DataGridViewIf DoubleBuffered is set to true in a derived DataGridView control, users will not receive visual feedback when resizing rows, columns, or headers or when reordering columns.
