例外

InvalidEnumArgumentException

当设置此属性时，指定的值不是有效的 DataGridViewColumnHeadersHeightSizeMode 值。

示例

下面的代码示例演示如何在主要用于显示的控件中使用 DataGridView 此属性。 在此示例中，控件的视觉外观通过多种方式进行自定义，并且控件配置为有限的交互性。 此示例是类概述中提供的大型示例的 DataGridViewCellStyle 一部分。

// 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;

    // Set property values appropriate for read-only display and 
    // limited interactivity. 
    dataGridView1.AllowUserToAddRows = false;
    dataGridView1.AllowUserToDeleteRows = false;
    dataGridView1.AllowUserToOrderColumns = true;
    dataGridView1.ReadOnly = true;

    // value won't override DataGridView.DefaultCellStyle.SelectionBackColor.

    dataGridView1.RowHeadersDefaultCellStyle.BackColor = Color.Black;

    // Set the Format property on the "Last Prepared" column to cause
    // the DateTime to be formatted as "Month, Year".
    dataGridView1.Columns["Last Prepared"].DefaultCellStyle.Format = "y";

    // Specify a larger font for the "Ratings" column. 
    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.
    dataGridView1.CellFormatting += new
        DataGridViewCellFormattingEventHandler(dataGridView1_CellFormatting);
}

注解

当此属性设置为 AutoSize 时，用户无法调整列标题的高度。

若要以编程方式调整列标题的高度，请使用 AutoResizeColumnHeadersHeight 该方法或设置 ColumnHeadersHeight 属性。

若要设置行标题的大小调整模式，请使用 RowHeadersWidthSizeMode 该属性。

要使单元格内容在调整列标题的大小时换行到多行上，单元格样式实际上必须具有 WrapMode 属性值 True。

有关标头大小调整的详细信息，请参阅 Windows 窗体 DataGridView 控件中的大小调整选项。

备注

控件 DataGridView 不支持双重缓冲。 如果 DoubleBuffered 设置为 true 在派生 DataGridView 控件中，则当用户调整行、列或标题大小或重新排序列时不会收到视觉反馈。
