将文本在DataGridView的单元格中竖直显示,需要在CellPainting事件中设置StringFormatFlag.DirectionVertical

using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication2
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
DataTable dt = new DataTable();

dt.Columns.Add("c1");

dt.Columns.Add("c2");

for (int j = 0; j < 10; j++)
{

dt.Rows.Add("aaaaaaaaa", "bbbb");

}

this.dataGridView1.DataSource = dt;



this.dataGridView1.CellPainting += new

DataGridViewCellPaintingEventHandler(dataGridView1_CellPainting); ;


}

private void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
{
if (e.ColumnIndex == 1 && e.RowIndex > -1 && e.Value != null)
{

e.Paint(e.CellBounds, DataGridViewPaintParts.All

& ~DataGridViewPaintParts.ContentForeground);

StringFormat sf = new StringFormat();

sf.Alignment = StringAlignment.Center;

sf.LineAlignment = StringAlignment.Center;

sf.FormatFlags = StringFormatFlags.DirectionVertical;

e.Graphics.DrawString(e.Value.ToString(), e.CellStyle.Font,

new SolidBrush(e.CellStyle.ForeColor), e.CellBounds, sf);

e.Handled = true;

}


}
