public:
 property System::Windows::Forms::DataGridViewCellStyle ^ RowHeadersDefaultCellStyle { System::Windows::Forms::DataGridViewCellStyle ^ get(); void set(System::Windows::Forms::DataGridViewCellStyle ^ value); };
public System.Windows.Forms.DataGridViewCellStyle RowHeadersDefaultCellStyle { get; set; }

Public Property RowHeadersDefaultCellStyle As DataGridViewCellStyle

プロパティ値

行ヘッダー セルに適用される既定のスタイルを表す DataGridViewCellStyleThe DataGridViewCellStyle that represents the default style applied to the row header cells.

次のコード例は、 DataGridViewカスタム色を持つでこのプロパティを使用する方法を示しています。The following code example illustrates how to use this property in a DataGridView with custom colors. DataGridViewCellStyle.SelectionBackColor Color.Empty値がオブジェクトから継承されるように、プロパティがに設定されていることに注意してください。DefaultCellStyleNote how the DataGridViewCellStyle.SelectionBackColor property is set to Color.Empty so that the value is inherited from the DefaultCellStyle object.

この例は、 DataGridViewCellStyleクラスの概要で提供されている大規模な例の一部です。This example is part of a larger example provided in the DataGridViewCellStyle class overview.

// Configures the appearance and behavior of a DataGridView control.
private void InitializeDataGridView()
{
    // Initialize basic DataGridView properties.
    dataGridView1.Dock = DockStyle.Fill;
    dataGridView1.BackgroundColor = Color.LightGray;
    dataGridView1.BorderStyle = BorderStyle.Fixed3D;

    // limited interactivity.

注釈

このプロパティDataGridViewCellStyleによって返される既定値には、次の初期プロパティ値があります。The default DataGridViewCellStyle returned by this property has the following initial property values.

DataGridViewCellStyle プロパティDataGridViewCellStyle property 既定値Default value
BackColor SystemBrushes.Control プロパティの値。The value of the SystemBrushes.Control property.
ForeColor SystemBrushes.WindowText プロパティの値。The value of the SystemBrushes.WindowText property.
SelectionBackColor SystemBrushes.Highlight プロパティの値。The value of the SystemBrushes.Highlight property.
SelectionForeColor SystemBrushes.HighlightText プロパティの値。The value of the SystemBrushes.HighlightText property.
Font Font プロパティの値。The value of the Font property.
Alignment DataGridViewContentAlignment.MiddleLeft
WrapMode DataGridViewTriState.True

これらの値は、 DefaultCellStyleプロパティによって設定された値を自動的にオーバーライドします。These values automatically override the values set through the DefaultCellStyle property. 行ヘッダーにDefaultCellStyle値を強制的に継承させるには、 RowHeadersDefaultCellStyleオブジェクトの値をDataGridViewCellStyleクラスに指定されている既定値に設定する必要があります。To force row headers to inherit the DefaultCellStyle values, you must set the values in the RowHeadersDefaultCellStyle object to the default values indicated for the DataGridViewCellStyle class.

セルスタイルの継承の詳細については、「 Windows フォーム DataGridView コントロールのセルのスタイル」を参照してください。For more information about cell style inheritance, see Cell Styles in the Windows Forms DataGridView Control.
