DataGridView.AllowUserToResizeRows DataGridView.AllowUserToResizeRows DataGridView.AllowUserToResizeRows DataGridView.AllowUserToResizeRows Property

定義

ユーザーが行のサイズを変更できるかどうかを示す値を取得または設定します。Gets or sets a value indicating whether users can resize rows.

public:
 property bool AllowUserToResizeRows { bool get(); void set(bool value); };
public bool AllowUserToResizeRows { get; set; }
member this.AllowUserToResizeRows : bool with get, set
Public Property AllowUserToResizeRows As Boolean

プロパティ値

すべての行のサイズを変更できる場合はtrue 。それ以外の場合は falsetrue if all the rows are resizable; otherwise, false. 既定値は、true です。The default is true.

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()

    // limited interactivity.

        dataGridView1.DefaultCellStyle.Font.FontFamily, 25, FontStyle.Bold))

注釈

ユーザーが行の高さを手動で変更できないようにするには、このプロパティを使用します。Use this property to prevent users from manually changing row heights. これは、たとえば、データが1回読み込まれ、その時点で行のサイズが変更される場合に、表示専用のコントロールを使用すると便利です。This is useful, for example, with display-only controls where data is loaded once and rows are resized at that time.

行のサイズが変更されたときにセルの内容を複数の行に折り返すには、セルに対しWrapModeて有効なTrueセルスタイルのプロパティ値がである必要があります。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.

ユーザーのサイズ変更の詳細については、「 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 user resizing, 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.
