同样是重载OnPaint 方法,但是方法应该是比较巧妙的!而且不用担心标题是不是有显示,也不用去计算坐标,很方便的说!

protected override void OnPaint(PaintEventArgs e)

{

base.OnPaint(e);

if(this.DataSource!=null)

{

if( this.VisibleRowCount == 0 )return;

Rectangle currRct;

int iRowCount = this.VisibleRowCount;

string sText = "";

int nowY = 0;

for( int i = 0 ; i < iRowCount ; i++ )

{

currRct = (Rectangle)this.GetCellBounds( i, 0 );

nowY = currRct.Y + 2;

sText = string.Format( " {0}", i+1 );

e.Graphics.DrawString( sText, this.Font, new SolidBrush(Color.Black), 10, nowY );

}

}

}
