我正在尝试创建一个包含许多控件的自定义面板。这是我第一次创建这样的自定义控件。此示例包含一个面板，该面板内有一个按钮。
我不确定为什么单击按钮时面板没有添加到 Form1 中。
我在我的代码中遗漏了什么吗？
private void button2_Click(object sender, EventArgs e)
{
streamingPanel sp = new streamingPanel();
sp.Size = new Size(319, 240);
Point point = new Point(50, 50);
sp.Location = point;
this.Controls.Add(sp);
}
public class streamingPanel : Panel
{
public System.Windows.Forms.Panel panel1;
public System.Windows.Forms.Button button1;
public streamingPanel()
{
InitializeComponent();
}
private void InitializeComponent()
{
this.panel1 = new System.Windows.Forms.Panel();
this.button1 = new System.Windows.Forms.Button();
this.panel1.SuspendLayout();
//
// panel1
//
this.panel1.BorderStyle = System.Windows.Forms.BorderStyle.FixedSingle;
this.panel1.Controls.Add(this.button1);
this.panel1.Location = new System.Drawing.Point(483, 91);
this.panel1.Name = "panel1";
this.panel1.Size = new System.Drawing.Size(319, 240);
this.panel1.TabIndex = 0;
//
// button1
//
this.button1.Location = new System.Drawing.Point(100, 72);
this.button1.Name = "button1";
this.button1.Size = new System.Drawing.Size(75, 23);
this.button1.TabIndex = 0;
this.button1.Text = "button1";
this.button1.UseVisualStyleBackColor = true;
}
}
