C＃無法在TableLayoutPanel中動態平均地自動調整列大小

Question

我有一個具有TableLayoutPanel控件的WinForm。 我的代碼將檢測屏幕上已連接的監視器的數量，為每個監視器創建一列，然后在TableLayoutControl每個單獨的列中為每個顯示添加一個按鈕，這樣我就可以確保無論連接了多少個監視器，該按鈕都將出現在表格中“居中”。 一個/兩個監視器可以很好地渲染，但是三個監視器會導致末端列分布不均勻。

這是我的代碼：

            int count = Screen.AllScreens.Count();
            this.monitorLayoutPanel.ColumnCount = count;

            ColumnStyle cs = new ColumnStyle(SizeType.Percent, 100 / count);
            this.monitorLayoutPanel.ColumnStyles.Add(cs);

            this.monitorLayoutPanel.AutoSize = true;

            var buttonSize = new Size(95, 75);

            int z = 0;
            foreach (var screen in Screen.AllScreens.OrderBy(i => i.Bounds.X))
            {

                Button monitor = new Button
                {
                    Name = "Monitor" + screen,
                    AutoSize = true,
                    Size = buttonSize,

                    BackgroundImageLayout = ImageLayout.Stretch,                                                  
                    BackgroundImage = Properties.Resources.display_enabled,
                    TextAlign = ContentAlignment.MiddleCenter,
                    Font = new Font("Segoe UI", 10, FontStyle.Bold),
                    ForeColor = Color.White,
                    BackColor = Color.Transparent,
                    Text = screen.Bounds.Width + "x" + screen.Bounds.Height,
                    Anchor = System.Windows.Forms.AnchorStyles.None
                };


                this.monitorLayoutPanel.Controls.Add(monitor, z, 0);
                z++;
                monitor.MouseClick += new MouseEventHandler(monitor_Click);
            }

我嘗試使按鈕更小，並增加了表單大小，但最后一列始終小於前兩列。 我聽不懂！

Answer 1

首先清除ColumnStyles。

this.monitorLayoutPanel.ColumnStyles.Clear();

然后：

int count = Screen.AllScreens.Count();

for (int i = 0; i < count; i++)
{
    ColumnStyle cs = new ColumnStyle(SizeType.Percent, (float)100 / count);
    this.monitorLayoutPanel.ColumnStyles.Add(cs);
}

this.monitorLayoutPanel.AutoSize = true;

...

Reza Aghaei向我指出了該線程。 如何使用Windows窗體創建魔術方塊？ 這為我指明了正確的方向。 更新（和工作）下面的代碼。 :)

            int screens = Screen.AllScreens.Count();
            this.monitorLayoutPanel.ColumnStyles.Clear();
            this.monitorLayoutPanel.ColumnCount = screens;            
            this.monitorLayoutPanel.AutoSize = true;

            int z = 0;
            foreach (var screen in Screen.AllScreens.OrderBy(i => i.Bounds.X))
            {
                var percent = 100f / screens;
                this.monitorLayoutPanel.ColumnStyles.Add(new ColumnStyle(SizeType.Percent, percent));

                Button monitor = new Button
                {
                    Name = "Monitor" + screen,
                    Size = new Size(95, 75),
                    BackgroundImageLayout = ImageLayout.Stretch,                                                  
                    BackgroundImage = Properties.Resources.display_enabled,
                    TextAlign = ContentAlignment.MiddleCenter,
                    Font = new Font("Segoe UI", 10, FontStyle.Bold),
                    ForeColor = Color.White,
                    BackColor = Color.Transparent,
                    Text = screen.Bounds.Width + "x" + screen.Bounds.Height,
                    Anchor = System.Windows.Forms.AnchorStyles.None
                };


                this.monitorLayoutPanel.Controls.Add(monitor, z, 0);
                z++;
                monitor.MouseClick += new MouseEventHandler(monitor_Click);
