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; }
member this.RowHeadersDefaultCellStyle : System.Windows.Forms.DataGridViewCellStyle with get, set
Public Property RowHeadersDefaultCellStyle As DataGridViewCellStyle

Property Value

Объект DataGridViewCellStyle, представляющий стиль по умолчанию, применяемый к ячейкам заголовков строк. The DataGridViewCellStyle that represents the default style applied to the row header cells.

Examples

В следующем примере кода показано, как использовать это свойство в DataGridView с помощью пользовательских цветов.The following code example illustrates how to use this property in a DataGridView with custom colors. Обратите внимание как DataGridViewCellStyle.SelectionBackColor свойству Color.Empty таким образом, чтобы значение наследуется из DefaultCellStyle объекта.Note how the DataGridViewCellStyle.SelectionBackColor property is set to Color.Empty so that the value is inherited from the DefaultCellStyle object.

Этот пример является частью большего примера, приведенного в DataGridViewCellStyle Общие сведения о классе.This example is part of a larger example provided in the DataGridViewCellStyle class overview.

Remarks

Значение по умолчанию DataGridViewCellStyle возвращаемые это свойство имеет следующие исходные значения свойств.The default DataGridViewCellStyle returned by this property has the following initial property values.

Свойство DataGridViewCellStyleDataGridViewCellStyle property Значение по умолчаниюDefault value
BackColor Значение свойства SystemBrushes.Control.The value of the SystemBrushes.Control property.
ForeColor Значение свойства SystemBrushes.WindowText.The value of the SystemBrushes.WindowText property.
SelectionBackColor Значение свойства SystemBrushes.Highlight.The value of the SystemBrushes.Highlight property.
SelectionForeColor Значение свойства SystemBrushes.HighlightText.The value of the SystemBrushes.HighlightText property.
Font Значение свойства Font.The value of the Font property.
Alignment DataGridViewContentAlignment.MiddleLeft
WrapMode DataGridViewTriState.True

Эти значения автоматически переопределяют значения, заданные через DefaultCellStyle свойство.These values automatically override the values set through the DefaultCellStyle property. Чтобы принудительно заголовков строк для наследования DefaultCellStyle значения, необходимо задать значения RowHeadersDefaultCellStyle объекта значения по умолчанию, указанном для DataGridViewCellStyle класса.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.
