DataGridView.AlternatingRowsDefaultCellStyle Property

Gets or sets the default cell style applied to odd-numbered rows of the DataGridView.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)
'Declaration
Public Property AlternatingRowsDefaultCellStyle As DataGridViewCellStyle

Property Value

Type: System.Windows.Forms.DataGridViewCellStyle
A DataGridViewCellStyle to apply to the odd-numbered rows.

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 rows with odd index numbers, the styles specified through the AlternatingRowsDefaultCellStyle property override the styles specified through the DefaultCellStyle, DataGridViewColumn.DefaultCellStyle, and RowsDefaultCellStyle, and are overridden by the styles specified through the DataGridViewRow.DefaultCellStyle and DataGridViewCell.Style properties.

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 to create a ledger effect in a DataGridView control. This example is part of a larger example available in the DataGridViewCellStyle class overview.

' 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

    ' 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.  
    Dim font As New Font( _
        dataGridView1.DefaultCellStyle.Font.FontFamily, 25, FontStyle.Bold)
    Try
        dataGridView1.Columns("Rating").DefaultCellStyle.Font = font
    Finally
        font.Dispose()
    End Try 

End Sub
