示例

下面的代码示例演示如何使用此枚举中仅显示,非交互式DataGridView控件。The following code example illustrates the use of this enumeration in a display-only, non-interactive DataGridView control.

// 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;
    dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
    dataGridView1.MultiSelect = false;
    dataGridView1.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.None;
    dataGridView1.AllowUserToResizeColumns = false;
    dataGridView1.ColumnHeadersHeightSizeMode = 
        DataGridViewColumnHeadersHeightSizeMode.DisableResizing;
    dataGridView1.AllowUserToResizeRows = false;
    dataGridView1.RowHeadersWidthSizeMode = 
        DataGridViewRowHeadersWidthSizeMode.DisableResizing;

    // Set the selection background color for all the cells.
    dataGridView1.DefaultCellStyle.SelectionBackColor = Color.White;
    dataGridView1.DefaultCellStyle.SelectionForeColor = Color.Black;

    // Set RowHeadersDefaultCellStyle.SelectionBackColor so that its default
    // value won't override DataGridView.DefaultCellStyle.SelectionBackColor.
    dataGridView1.RowHeadersDefaultCellStyle.SelectionBackColor = Color.Empty;

    // Set the background color for all rows and for alternating rows. 
    // The value for alternating rows overrides the value for all rows. 
    dataGridView1.RowsDefaultCellStyle.BackColor = Color.LightGray;
    dataGridView1.AlternatingRowsDefaultCellStyle.BackColor = Color.DarkGray;

    // Set the row and column header styles.
    dataGridView1.ColumnHeadersDefaultCellStyle.ForeColor = Color.White;
    dataGridView1.ColumnHeadersDefaultCellStyle.BackColor = Color.Black;
    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

默认情况下,用户可以调整大小的行标题的宽度。By default, users can resize the width of the row headers. 您可以禁用此功能设置固定的宽度,或者可以使用基于内容的自动调整大小模式下,它也可以禁止用户调整大小。You can disable this ability to set a fixed width, or you can use a content-based automatic sizing mode, which also disables user resizing.

DataGridView控件可以调整以适应其所有内容,其行标题的宽度,仅第一个标头的内容或仅的内容当前显示的标头。The DataGridView control can adjust the width of its row headers to fit all their contents, only the contents of the first header, or only the contents of currently displayed headers. 计算新宽度使用的标头部分是有助于使用很多行数据时避免对性能产生负面影响。Calculating the new width using a subset of headers is useful to avoid a performance penalty when working with many rows of data.

此枚举由DataGridView控制RowHeadersWidthSizeMode属性和AutoResizeRowHeadersWidth方法。This enumeration is used by the DataGridView control RowHeadersWidthSizeMode property and AutoResizeRowHeadersWidth method.

有关调整大小模式的详细信息,请参阅Windows 窗体 DataGridView 控件中的大小调整选项For more information about sizing modes, see Sizing Options in the Windows Forms DataGridView Control.
