关于DataGridView控件的一个小问题

[dentance]

如下的代码来自msdn08，我的问题是，行没有充满整个大小时，下方的灰色背景色如何改变，或者，持续添加行，当出现竖直滚动条时，最下面行下的灰色背景如何改变？
using System;
using System.Drawing;
using System.Windows.Forms;

public class Form1 : System.Windows.Forms.Form
{
private Panel buttonPanel = new Panel();
private DataGridView songsDataGridView = new DataGridView();
private Button addNewRowButton = new Button();
private Button deleteRowButton = new Button();

public Form1()
{
this.Load += new EventHandler(Form1_Load);
}

private void Form1_Load(System.Object sender, System.EventArgs e)
{
SetupLayout();
SetupDataGridView();
PopulateDataGridView();
}

private void songsDataGridView_CellFormatting(object sender,
System.Windows.Forms.DataGridViewCellFormattingEventArgs e)
{
if (this.songsDataGridView.Columns[e.ColumnIndex].Name == "Release Date")
{
if (e != null)
{
if (e.Value != null)
{
try
{
e.Value = DateTime.Parse(e.Value.ToString())
.ToLongDateString();
e.FormattingApplied = true;
}
catch (FormatException)
{
Console.WriteLine("{0} is not a valid date.", e.Value.ToString());
}
}
}
}
}

private void addNewRowButton_Click(object sender, EventArgs e)
{
this.songsDataGridView.Rows.Add();
}

private void deleteRowButton_Click(object sender, EventArgs e)
{
if (this.songsDataGridView.SelectedRows.Count > 0 &&
this.songsDataGridView.SelectedRows[0].Index !=
this.songsDataGridView.Rows.Count - 1)
{
this.songsDataGridView.Rows.RemoveAt(
this.songsDataGridView.SelectedRows[0].Index);
}
}

private void SetupLayout()
{
this.Size = new Size(600, 500);

addNewRowButton.Text = "Add Row";
addNewRowButton.Location = new Point(10, 10);

deleteRowButton.Click += new EventHandler(deleteRowButton_Click);

buttonPanel.Controls.Add(addNewRowButton);
buttonPanel.Controls.Add(deleteRowButton);
buttonPanel.Height = 50;
buttonPanel.Dock = DockStyle.Bottom;

this.Controls.Add(this.buttonPanel);
}

private void SetupDataGridView()
{
this.Controls.Add(songsDataGridView);

songsDataGridView.ColumnCount = 5;

songsDataGridView.ColumnHeadersDefaultCellStyle.BackColor = Color.Navy;
songsDataGridView.ColumnHeadersDefaultCellStyle.ForeColor = Color.White;
songsDataGridView.ColumnHeadersDefaultCellStyle.Font =
new Font(songsDataGridView.Font, FontStyle.Bold);

songsDataGridView.Name = "songsDataGridView";
songsDataGridView.Location = new Point(8, 8);
songsDataGridView.Size = new Size(500, 250);
// songsDataGridView.AutoSizeRowsMode =
// DataGridViewAutoSizeRowsMode.DisplayedCellsExceptHeaders;
songsDataGridView.ColumnHeadersBorderStyle =
DataGridViewHeaderBorderStyle.Single;
songsDataGridView.CellBorderStyle = DataGridViewCellBorderStyle.Single;
songsDataGridView.GridColor = Color.Black;
songsDataGridView.RowHeadersVisible = false;
songsDataGridView.ColumnHeadersVisible = false;

}

{

设置一下DataGridView的背景即可

//设置为白色背景
songsDataGridView.BackgroundColor = Color.White;

很好很强大

[wuyq11]

设置背景图片或背景色
protected override void PaintBackground(Graphics graphics, Rectangle clipBounds, Rectangle gridBounds)
{
base.PaintBackground(graphics, clipBounds, gridBounds);
if(m_Image != (Image)null)
graphics.DrawImage(m_Image, gridBounds);
}
添加行设置行高DataGridViewRow dr = dataGridView1.Rows[dataGridView1.NewRowIndex];
dataGridView1.Rows.Add(dr);

虽然可以去掉灰色，但是下方的一条还是留白了，我目前是固定行高解决之，使得滚动条下边沿和最后一行的下边对齐。但这样做不太灵活，不知有无更加做法。

[dentance]

我说的滚动条是竖直的滚动条。
