动态按钮创建和放大器;将它们放置在一个predefined以便使用C＃ [英] Dynamic button creation & placing them in a predefined order using c#

问题描述

NET 4.5 C＃创建一个Windows窗体。我要动态地创建和放大器;添加按钮和放大器;也为它们分配单击事件，但希望他们能够动态地放置在一个特殊的方式，就像图像

NET 4.5 C# to create a windows form. I want to dynamically create & add buttons & also assign them click events but want them to be dynamically placed in a particular fashion just like the image

我的问题是如何动态地放置按钮以上述方式，即4×4格式（4个按键成一排，4列，但无限行）。是有可能在Win形式这样做？

My question is how do i place the buttons dynamically in the above fashion i.e. 4x4 format (4 buttons in a row, 4 columns but unlimited rows).Is it possible to do so in win forms??.

presently我试图下面提到的code，但有没有明确的想法，我如何放置按钮如上图

Presently i'm trying the below mentioned code but having no clear idea as to how do i place the buttons as shown above

        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;
           // ...
        }
     }
  }

请指教与codeS的解决方案。先谢谢了。

Please advise solution with codes. Thanks in advance.

推荐答案

您可以使用的 TableLayoutPanel中 ，并动态地创建按钮并将其添加到面板。

You can use a TableLayoutPanel and create your buttons dynamically and add them to the panel.

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));
}

请注意：

• 使用 TableLayoutPanel.Controls.Add（控制），我们可以按顺序将控件添加到面板。


• 使用 TableLayoutPanel中。 Controls.Add被（控制，参数：columnIndex和rowIndex） 我们可以在特定的细胞中添加控件。

• Using TableLayoutPanel.Controls.Add(control) we can add controls sequentially to the panel.
• Using TableLayoutPanel.Controls.Add(control, columnIndex, rowIndex) we can add controls at specific cells.
