現在の Graphics の描画に使用する DataGridViewRowThe Graphics used to paint the current DataGridViewRow.

次のコード例は、使用する方法を示します、Graphicsカスタム背景を描画するプロパティ。The following code example demonstrates how to use the Graphics property to paint the custom background. 変数、eの種類はDataGridViewRowPrePaintEventArgsします。The variable, e, is of type DataGridViewRowPrePaintEventArgs. このコード例で示されている例の一部は、方法。Windows フォームの DataGridView コントロール内の行の外観をカスタマイズします。This code example is part of a larger example provided in How to: Customize the Appearance of Rows in the Windows Forms DataGridView Control.

// Determine whether the cell should be painted
// with the custom selection background.
if ((e.State & DataGridViewElementStates.Selected) ==
            DataGridViewElementStates.Selected)
{
    // Calculate the bounds of the row.
    Rectangle rowBounds = new Rectangle(
        this.dataGridView1.RowHeadersWidth, e.RowBounds.Top,
        this.dataGridView1.Columns.GetColumnsWidth(
            DataGridViewElementStates.Visible) -
        this.dataGridView1.HorizontalScrollingOffset + 1,
        e.RowBounds.Height);

    // Paint the custom selection background.
    using (Brush backbrush =
        new System.Drawing.Drawing2D.LinearGradientBrush(rowBounds,
            this.dataGridView1.DefaultCellStyle.SelectionBackColor,
            e.InheritedRowStyle.ForeColor,
            System.Drawing.Drawing2D.LinearGradientMode.Horizontal))
    {
        e.Graphics.FillRectangle(backbrush, rowBounds);
    }
}
' Determine whether the cell should be painted with the 
' custom selection background.
If (e.State And DataGridViewElementStates.Selected) = _
    DataGridViewElementStates.Selected Then

    ' Calculate the bounds of the row.
    Dim rowBounds As New Rectangle( _
        Me.dataGridView1.RowHeadersWidth, e.RowBounds.Top, _
        Me.dataGridView1.Columns.GetColumnsWidth( _
        DataGridViewElementStates.Visible) - _
        Me.dataGridView1.HorizontalScrollingOffset + 1, _
        e.RowBounds.Height)

    ' Paint the custom selection background.
    Dim backbrush As New _

        System.Drawing.Drawing2D.LinearGradientMode.Horizontal)
    Try
        e.Graphics.FillRectangle(backbrush, rowBounds)
    Finally
        backbrush.Dispose()
    End Try
End If
