示例

下面的代码示例演示如何在仅显示、非交互式DataGridView控件中使用此枚举。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);
}
' Configures the appearance and behavior of a DataGridView control.
Private Sub InitializeDataGridView()

    ' Initialize basic DataGridView properties.
    dataGridView1.Dock = DockStyle.Fill
    dataGridView1.BackgroundColor = Color.LightGray
    dataGridView1.BorderStyle = BorderStyle.Fixed3D

    dataGridView1.ReadOnly = True
    dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect

    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. 
    Dim font As New Font( _
        dataGridView1.DefaultCellStyle.Font.FontFamily, 25, FontStyle.Bold)

注解

默认情况下, 用户可以调整行标题的宽度。By default, users can resize the width of the row headers. 您可以禁用此功能以设置固定宽度, 也可以使用基于内容的自动大小调整模式, 这也会禁用用户大小调整。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控件可以调整其行标题的宽度以适应其所有内容、仅显示第一个标头的内容, 或者只调整当前显示的标头的内容。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. 使用标头子集计算新宽度有助于避免在处理多行数据时出现性能损失。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控件RowHeadersWidthSizeMode属性和AutoResizeRowHeadersWidth方法使用。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 控件中的调整大小选项For more information about sizing modes, see Sizing Options in the Windows Forms DataGridView Control.
