如何在TableLayoutPanel中动态缩放控件大小

Question

我的目标是使用TableLayoutPanel创建一个按钮网格来表示我的2d数组。

当前，我可以获得正确数量的列和行，并将按钮添加到正确的位置。

我遇到的问题是按钮的缩放。我已经尝试过other solutions，但它们似乎没有用。

填写表格

int[,] testArr = new int[,] { { 1, 2, 3, 4 }, { 5, 6, 7, 8 }, { 9, 10, 11, 12 }, { 13, 14, 15, 16 } };

        tableLayoutPanel_TopView.ColumnCount = testArr.GetLength(0);
        tableLayoutPanel_TopView.RowCount = testArr.GetLength(1);
        tableLayoutPanel_TopView.AutoSize = true;

        for (int y = 0; y < testArr.GetLength(1); y++)
        {
            for (int x = 0; x < testArr.GetLength(0); x++)
            {
                Button btn = new Button
                {
                    Text = x.ToString() + "." + y.ToString(),
                    Dock = DockStyle.Fill,
                };
                tableLayoutPanel_TopView.Controls.Add(btn);
            }
        }

        Single percHeight = ((Single)1 / (Single)tableLayoutPanel_TopView.RowStyles.Count) * 100;
        Single percWidth = ((Single)1 / (Single)tableLayoutPanel_TopView.ColumnStyles.Count) * 100;

        foreach (ColumnStyle style in tableLayoutPanel_TopView.ColumnStyles)
        {
            style.SizeType = SizeType.Percent;
            style.Width = percWidth;
        }

        foreach (RowStyle style in tableLayoutPanel_TopView.RowStyles)
        {
            style.SizeType = SizeType.Percent;
            style.Height = percHeight;
        }

TableLayoutPanel设置

        this.tableLayoutPanel_TopView.ColumnCount = 1;
        this.tableLayoutPanel_TopView.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle());
        this.tableLayoutPanel_TopView.Dock = System.Windows.Forms.DockStyle.Fill;
        this.tableLayoutPanel_TopView.Location = new System.Drawing.Point(3, 16);
        this.tableLayoutPanel_TopView.Name = "tableLayoutPanel_TopView";
        this.tableLayoutPanel_TopView.RowCount = 1;
        this.tableLayoutPanel_TopView.RowStyles.Add(new System.Windows.Forms.RowStyle());
        this.tableLayoutPanel_TopView.Size = new System.Drawing.Size(638, 463);
        this.tableLayoutPanel_TopView.TabIndex = 0;

但是，这将产生以下结果：

Current table

如您所见，每个按钮的宽度和高度似乎仅从第二列和第二行开始才有意义。我该怎么做才能使每个按钮的大小相同？

解决方案

我已通过清除ColumnStyles和RowStyles并为每一行和每一列添加新样式来解决此问题。每个样式的SizeType设置为Percent，并计算宽度/高度。

代码

我已将testArr替换为功能所在的集合sortedContainers。

       // above code hasn't changed
        Single percHeight = ((Single)1 / (Single)tableLayoutPanel_TopView.RowStyles.Count) * 100;
        Single percWidth = ((Single)1 / (Single)tableLayoutPanel_TopView.ColumnStyles.Count) * 100;

        tableLayoutPanel_TopView.ColumnStyles.Clear();
        tableLayoutPanel_TopView.RowStyles.Clear();

        for (int x = 0; x < sortedContainers.Width; x++)
        {
            tableLayoutPanel_TopView.ColumnStyles.Add(new ColumnStyle
            {
                SizeType = SizeType.Percent,
                Width = percWidth
            });
        }

        for (int y = 0; y < sortedContainers.Length; y++)
        {
            tableLayoutPanel_TopView.RowStyles.Add(new RowStyle
            {
                SizeType = SizeType.Percent,
                Height = percHeight
            });
        }
