以编程方式更改行/列跨度(tablelayoutpanel)

问题描述

我有一个tablelayoutpanel.2x2-2列2行.

I have a tablelayoutpanel. 2x2 - 2 columns 2 rows.

例如，我在第一行第二列中添加了一个按钮 button1 . button1 的Dock属性设置为Fill.VS Designer允许设置 button1 的列/行跨度属性.

For example, I added a button button1 in a 1 row, second column. button1 has a dock property set to Fill. VS Designer allows to set column/row span properties of button1.

我希望可用性以编程方式更改 button1 的行跨度属性，以便它可以填充所有第二列(第一行和第二行)和可用性以将其重新设置

I want an availability to change row span property of button1 programatically, so it can fill all second column(1 row and second row) and availability to set it back.

如何?

推荐答案

这段代码呢?

private void button1_Click(object sender, EventArgs e)
{
    var control = sender as Control;

    if(control == null)
        return;

    if (1 == tableLayoutPanel1.GetRowSpan(control))
    {
        tableLayoutPanel1.SetRowSpan(control, 2);
    }
    else
    {
        tableLayoutPanel1.SetRowSpan(control, 1);
    }
}
