繪製的水平線，一個DataGridView細胞

Question

這是我PANEL1漆事件

Pen graphPen = new Pen(Color.White, 10); 
PointF pt1D = new PointF(); 
PointF pt2D = new PointF(); 
pt1D.X = 5; 
pt1D.Y = 10; 
pt2D.X = 175; 
pt2D.Y = 10; 

e.Graphics.DrawLine(graphPen, pt1D, pt2D); 
e.Graphics.DrawLine(graphPen, 5, 10, 175, 10); 

幫我datagridview的電池漆事件同樣的方法適用。 我想對datagridview的細胞

，這是不利於實際應用繪製的DrawLine，但如果你必須做到這一點，你可以使用這個

//subscribing the event 
dataGridView1.CellPainting += dataGridView1_CellPainting; 

//handle the event 
void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e) 
{ 

    if (e.RowIndex >= 0 && e.ColumnIndex >= 0) 
    { 
     e.Graphics.DrawLine(Pens.Red, e.CellBounds.Left, e.CellBounds.Top, e.CellBounds.Right, e.CellBounds.Bottom); 
     e.Graphics.DrawLine(Pens.Blue, e.CellBounds.Left, e.CellBounds.Top+e.CellBounds.Height/2, e.CellBounds.Right,e.CellBounds.Top+ e.CellBounds.Height/2); 

     e.Paint(e.ClipBounds, DataGridViewPaintParts.ContentForeground); 
     e.Handled = true; 
    } 
} 

，結果是一樣的：

但是，正如我前面說，不要用這個實際應用
