创建动态按钮并使用c#将它们置于预定义的顺序中

Question

NET 4.5 C#创建一个Windows窗体.我想动态创建和添加按钮并为它们分配点击事件,但希望它们像图像一样以特定方式动态放置.

我的问题是如何以上述方式动态放置按钮,即4x4格式(连续4个按钮,4列但无限行).是否有可能以获胜形式这样做？

目前我正在尝试下面提到的代码,但对于如何放置如上所示的按钮没有明确的想法.

        public Form1()
    {
        InitializeComponent();

        for (int i = 0; i < 5; i++)
        {
            Button button = new Button();
            button.Location = new Point(160, 30 * i + 10);
            button.Click += new EventHandler(ButtonClickCommonEvent);
            button.Tag = i;
            this.Controls.Add(button);
        }
    }

void ButtonClickCommonEvent(object sender, EventArgs e)
  {
     Button button = sender as Button;
     if (button != null)
     {       
        switch ((int)button.Tag)
        {
           case 0:
              // First Button Clicked
              break;
           case 1:
              // Second Button Clicked
              break;
           // ...
        }
     }
  }

请用代码告知解决方案.

您可以使用a TableLayoutPanel并动态创建按钮并将其添加到面板中.

例如:

private void Form1_Load(object sender, EventArgs e)
{
    var rowCount = 3;
    var columnCount = 4;

    this.tableLayoutPanel1.ColumnCount = columnCount;
    this.tableLayoutPanel1.RowCount = rowCount;

    this.tableLayoutPanel1.ColumnStyles.Clear();
    this.tableLayoutPanel1.RowStyles.Clear();

    for (int i = 0; i < columnCount; i++)
    {
        this.tableLayoutPanel1.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent, 100 / columnCount));
    }
    for (int i = 0; i < rowCount; i++)
    {
        this.tableLayoutPanel1.RowStyles.Add(new System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Percent, 100 / rowCount));
    }

    for (int i = 0; i < rowCount* columnCount; i++)
    {
        var b = new Button();
        b.Text = (i+1).ToString();
        b.Name = string.Format("b_{0}", i + 1);
        b.Click += b_Click;
        b.Dock = DockStyle.Fill;
        this.tableLayoutPanel1.Controls.Add(b);
    }
}

void b_Click(object sender, EventArgs e)
{
    var b = sender as Button;
    if (b != null)
        MessageBox.Show(string.Format("{0} Clicked", b.Text));
}

注意:

• 使用TableLayoutPanel.Controls.Add(control)我们可以按顺序向面板添加控件.
• 使用TableLayoutPanel.Controls.Add(control,?columnIndex,?rowIndex)我们可以在特定单元格中添加控件.
