更改 DataGridViews 中的所有单元格边框宽度

Question

我有一个数据网格视图，我想让所有的单元格边框变粗。有没有可以做到这一点的属性？

您需要通过向CellPainting 事件处理程序添加代码来进行一些自定义绘制。要将单元格边框设置为无，请使用 CellBorderStyle:

    dataGridView1.CellBorderStyle = DataGridViewCellBorderStyle.None;

// CellPainting event handler for your dataGridView1
private void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
{
    if (e.RowIndex == -1 && e.ColumnIndex > -1)
    {
       e.Handled = true;
       using (Brush b = new SolidBrush(dataGridView1.DefaultCellStyle.BackColor))
       {
         e.Graphics.FillRectangle(b, e.CellBounds);
       }
       using (Pen p = new Pen(Brushes.Black))
       {
         p.DashStyle = System.Drawing.Drawing2D.DashStyle.Dash;
         e.Graphics.DrawLine(p, new Point(0, e.CellBounds.Bottom-1), new Point(e.CellBounds.Right, e.CellBounds.Bottom-1));
       }
       e.PaintContent(e.ClipBounds);
    }
}
