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

属性值

DataGridViewCellStyle,表示应用于行标题单元格的默认样式。The DataGridViewCellStyle that represents the default style applied to the row header cells.

示例

下面的代码示例演示如何在具有自定义颜色的DataGridView中使用此属性。The following code example illustrates how to use this property in a DataGridView with custom colors. 请注意DataGridViewCellStyle.SelectionBackColor属性如何设置为Color.Empty ,以使DefaultCellStyle值从对象继承。Note how the DataGridViewCellStyle.SelectionBackColor property is set to Color.Empty so that the value is inherited from the DefaultCellStyle object.

此示例是DataGridViewCellStyle类概述中提供的一个更大示例的一部分。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;

    using (Font font = new Font(
        dataGridView1.DefaultCellStyle.Font.FontFamily, 25, FontStyle.Bold))
    {
        dataGridView1.Columns["Rating"].DefaultCellStyle.Font = font;
    }

    // Attach a handler to the CellFormatting event.

注解

此属性DataGridViewCellStyle返回的默认值具有以下初始属性值。The default DataGridViewCellStyle returned by this property has the following initial property values.

DataGridViewCellStyle 属性DataGridViewCellStyle property 默认值Default value
BackColor SystemBrushes.Control 属性的值。The value of the SystemBrushes.Control property.
ForeColor SystemBrushes.WindowText 属性的值。The value of the SystemBrushes.WindowText property.
SelectionBackColor SystemBrushes.Highlight 属性的值。The value of the SystemBrushes.Highlight property.
SelectionForeColor SystemBrushes.HighlightText 属性的值。The value of the SystemBrushes.HighlightText property.
Font Font 属性的值。The value of the Font property.
Alignment DataGridViewContentAlignment.MiddleLeft
WrapMode DataGridViewTriState.True

这些值自动覆盖通过DefaultCellStyle属性设置的值。These values automatically override the values set through the DefaultCellStyle property. 若要强制行标题继承这些DefaultCellStyle值,则必须将RowHeadersDefaultCellStyle对象中的值设置为为DataGridViewCellStyle类指定的默认值。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.
