C# user control as a custom panel
提问by Toto
I create my own user control which only contains a panel :
我创建了自己的用户控件，它只包含一个面板：
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.
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。
Is there a property/attribute I must set in order to perform this, an other way to do what I want ?
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？
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);
}
}

But if you only need extended Panel functionality its better to inherit directly from Panel.
但是如果您只需要扩展面板功能，最好直接从面板继承。

To be more precise, I do the following :
更准确地说，我执行以下操作：
[Designer(typeof(myControlDesigner))]
public class MyPanel : UserControl
{
private TableLayoutPanel tableLayoutPanel1;
private Panel panelMain;
...
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
public Panel InnerPanel
{
get { return panelMain; }
set { panelMain = value; }
}
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
public TableLayoutPanel InnerTableLayout
{
get { return tableLayoutPanel1; }
set { tableLayoutPanel1 = value; }
}
}
With myControlDesigner for [Designer(typeof(myControlDesigner))] to be
使用 myControlDesigner for [Designer(typeof(myControlDesigner))]
class myControlDesigner : ParentControlDesigner
{
public override void Initialize(IComponent component)
{
base.Initialize(component);
MyPanel myPanel = component as MyPanel;
this.EnableDesignMode(myPanel.InnerPanel, "InnerPanel");
this.EnableDesignMode(myPanel.InnerTableLayout, "InnerTableLayout");
}
}
