C# 用户控件作为自定义面板 [英] C# user control as a custom panel

问题描述

我创建了自己的用户控件，它只包含一个面板:

I create my own user control which only contains a panel :

当我在设计器中拖动一个 myPanel 对象，然后尝试在其上添加一个按钮时，该按钮实际上已添加到表单的控件中.

When I drag a myPanel object in the designer and then try to add a button on it, the button is in fact added to the form's controls.

是否有我必须设置的属性/属性才能执行此操作，另一种方式来做我想做的事?

Is there a property/attribute I must set in order to perform this, an other way to do what I want ?

public class MyPanel : UserControl
{
    private Panel panelMain;

    public MyPanel()
    {
        InitializeComponent();
    }

    private void InitializeComponent()
    {
        this.panelMain = new System.Windows.Forms.Panel();
        this.SuspendLayout();
        // 
        // panelMain
        // 
        this.panelMain.BackColor = System.Drawing.SystemColors.ActiveCaption;
        this.panelMain.Dock = System.Windows.Forms.DockStyle.Fill;
        this.panelMain.Location = new System.Drawing.Point(0, 0);
        this.panelMain.Name = "panelMain";
        this.panelMain.Size = new System.Drawing.Size(150, 150);
        this.panelMain.TabIndex = 0;
        // 
        // myPanel
        // 
        this.Controls.Add(this.panelMain);
        this.Name = "MyPanel";
        this.ResumeLayout(false);
    }
}

如何使用 Visual 使 UserControl 对象在设计时充当控件容器C#

但如果您只需要扩展 Panel 功能，最好直接从 Panel 继承.

But if you only need extended Panel functionality its better to inherit directly from Panel.
