DataGridViewRow.DefaultCellStyle Property

Note: This property is new in the .NET Framework version 2.0.

Gets or sets the default styles for the row, which are used to render cells in the row unless the styles are overridden.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public override DataGridViewCellStyle DefaultCellStyle { get; set; }
/** @property */
public DataGridViewCellStyle get_DefaultCellStyle ()

/** @property */
public void set_DefaultCellStyle (DataGridViewCellStyle value)

public override function get DefaultCellStyle () : DataGridViewCellStyle

public override function set DefaultCellStyle (value : DataGridViewCellStyle)

Property Value

The DataGridViewCellStyle to be applied as the default style.
Exception typeCondition

InvalidOperationException

When setting this property, the row is in a DataGridView control and is a shared row.

The DataGridView control displays its cells using the styles indicated by the cell InheritedStyle property, which inherits styles from other properties of type DataGridViewCellStyle. For cells in this row, the styles specified through the DefaultCellStyle property override the styles specified through the DataGridView.DefaultCellStyle, DataGridViewColumn.DefaultCellStyle, DataGridView.RowsDefaultCellStyle, and DataGridView.AlternatingRowsDefaultCellStyle properties, but are overridden by the styles specified through the DataGridViewCell.Style property.

For more information, see Cell Styles in the Windows Forms DataGridView Control.

When getting this property, a DataGridViewCellStyle with default values will be created if the property has not already been accessed. This can cause a performance impact when getting this property for many rows. Whenever possible, use a single DataGridViewCellStyle to set this property for multiple rows. For more information, see Best Practices for Scaling the Windows Forms DataGridView Control.

The following code example illustrates how to use this property in a DataGridView control intended primarily for display. In this example, the visual appearance of the control is customized in several ways and the control is configured for limited interactivity. This example is part of a larger example available 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;
    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);
}
