tablelayoutpanel 怎样合并单元格

[uncleson88]

我知道控件的RowSpan和ColumnSpan属性和tablelayoutpanel.SetRowSpan()，但是这样只是把控件变大，单元格上的线还在，如果CellBorderStyle = None 当然没事，可如果想要有边框的话就太丑了。
怎样实现真正的单元格合并呢？

自己继承一个，重载 OnPaintBackground 方法，在里面处理

边框可以不使用tablelayoutpanel的边框线，你在需要显示边框的时候，可以在一个单元格内放入一个Panel等容器，使用容易的边框线就可以了喔

Single的边框我还能写出来，如果是其他的有3D效果的。。。能给点方法吗？

下载 Reflector.exe 去反编译.net，看看tablelayoutpanel的 OnPaintBackground 代码就清楚了

它里面调用 ControlPaint.PaintTableCellBorder

以下是ControlPaint.PaintTableCellBorder代码

internal static void PaintTableCellBorder(TableLayoutPanelCellBorderStyle borderStyle, Graphics g, Rectangle bound)
{
    switch (borderStyle)
    {
        case TableLayoutPanelCellBorderStyle.None:
            return;

        case TableLayoutPanelCellBorderStyle.Single:
            g.DrawRectangle(SystemPens.ControlDark, bound);
            return;

        case TableLayoutPanelCellBorderStyle.Inset:
            using (Pen pen = new Pen(SystemColors.Window))
            {
                g.DrawLine(pen, bound.X, bound.Y, (bound.X + bound.Width) - 1, bound.Y);
                g.DrawLine(pen, bound.X, bound.Y, bound.X, (bound.Y + bound.Height) - 1);
            }
            g.DrawLine(SystemPens.ControlDark, (bound.X + bound.Width) - 1, bound.Y, (bound.X + bound.Width) - 1, (bound.Y + bound.Height) - 1);
            g.DrawLine(SystemPens.ControlDark, bound.X, (bound.Y + bound.Height) - 1, (bound.X + bound.Width) - 1, (bound.Y + bound.Height) - 1);
            return;

        case TableLayoutPanelCellBorderStyle.InsetDouble:
            g.DrawRectangle(SystemPens.Control, bound);
            bound = new Rectangle(bound.X + 1, bound.Y + 1, bound.Width - 1, bound.Height - 1);
            using (Pen pen2 = new Pen(SystemColors.Window))
            {
                g.DrawLine(pen2, bound.X, bound.Y, (bound.X + bound.Width) - 1, bound.Y);
                g.DrawLine(pen2, bound.X, bound.Y, bound.X, (bound.Y + bound.Height) - 1);
            }
            g.DrawLine(SystemPens.ControlDark, (bound.X + bound.Width) - 1, bound.Y, (bound.X + bound.Width) - 1, (bound.Y + bound.Height) - 1);
            g.DrawLine(SystemPens.ControlDark, bound.X, (bound.Y + bound.Height) - 1, (bound.X + bound.Width) - 1, (bound.Y + bound.Height) - 1);
            return;

        case TableLayoutPanelCellBorderStyle.Outset:
        {
            g.DrawLine(SystemPens.ControlDark, bound.X, bound.Y, (bound.X + bound.Width) - 1, bound.Y);
            g.DrawLine(SystemPens.ControlDark, bound.X, bound.Y, bound.X, (bound.Y + bound.Height) - 1);
            using (Pen pen3 = new Pen(SystemColors.Window))
            {
                g.DrawLine(pen3, (bound.X + bound.Width) - 1, bound.Y, (bound.X + bound.Width) - 1, (bound.Y + bound.Height) - 1);
                g.DrawLine(pen3, bound.X, (bound.Y + bound.Height) - 1, (bound.X + bound.Width) - 1, (bound.Y + bound.Height) - 1);
                return;
            }
        }
        case TableLayoutPanelCellBorderStyle.OutsetDouble:
        case TableLayoutPanelCellBorderStyle.OutsetPartial:
            g.DrawRectangle(SystemPens.Control, bound);
            bound = new Rectangle(bound.X + 1, bound.Y + 1, bound.Width - 1, bound.Height - 1);
            g.DrawLine(SystemPens.ControlDark, bound.X, bound.Y, (bound.X + bound.Width) - 1, bound.Y);
            g.DrawLine(SystemPens.ControlDark, bound.X, bound.Y, bound.X, (bound.Y + bound.Height) - 1);
            using (Pen pen4 = new Pen(SystemColors.Window))
            {
                g.DrawLine(pen4, (bound.X + bound.Width) - 1, bound.Y, (bound.X + bound.Width) - 1, (bound.Y + bound.Height) - 1);
                g.DrawLine(pen4, bound.X, (bound.Y + bound.Height) - 1, (bound.X + bound.Width) - 1, (bound.Y + bound.Height) - 1);
            }
            return;

        default:
            return;
    }
}

能教教我怎么反编译吗？.NET 在哪个文件里？
