定義

行ヘッダーを格納している列が表示され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 the column that contains row headers is displayed.

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

プロパティ値

行ヘッダーを格納している列が表示される場合はtrue 。それ以外の場合は falsetrue if the column that contains row headers is displayed; otherwise, false. 既定値は、true です。The default is true.

例外

このプロパティの設定時に指定した値は false であり、AutoSizeRowsMode プロパティは AllHeaders または DisplayedHeaders に設定されています。The specified value when setting this property is false and the AutoSizeRowsMode property is set to AllHeaders or DisplayedHeaders.

ColumnHeadersBorderStyle、、、 AutoSizeRowsMode 、、ColumnCount、、、、 ColumnHeadersDefaultCellStyleおよびの各プロパティを設定する方法を次のコード例に示します。BackgroundColor GridColor CellBorderStyle RowHeadersVisible SelectionMode MultiSelectThe following code example demonstrates how to set the ColumnHeadersDefaultCellStyle, AutoSizeRowsMode, ColumnHeadersBorderStyle, CellBorderStyle, GridColor, BackgroundColor, RowHeadersVisible, SelectionMode, ColumnCount, and MultiSelect properties. また、このコード例は、プロパティDataGridViewColumn.NameDataGridViewColumn.DefaultCellStyleプロパティを設定する方法を示しています。In addition, the code example demonstrates how to set the DataGridViewColumn.Name and DataGridViewColumn.DefaultCellStyle properties. この例を実行するにはDataGridView 、という名前dataGridView1のを含むフォームにコードを貼り付けてから、フォームのコンストラクターまたLoadはイベントハンドラーからメソッドをSetUpDataGridView呼び出します。To run this example, paste the code into a form that contains a DataGridView named dataGridView1, and then call the SetUpDataGridView method from the form's constructor or Load event handler. すべてのイベントがイベントハンドラーに関連付けられていることを確認します。Ensure all events are associated with their event handlers.
