我有一个用户控件,其中包含一个Panel 和一个TabControl。我为两者启用了设计时支持。我可以将工具箱中的控件拖/放到用户控件中的面板控件上。我还可以通过 TabControl 上的设计器添加和删除选项卡页。但是,我无法将任何控件拖/放到选项卡页本身上。
下面是我的用户控件的代码生成源代码:
partial class TestUserControl
{
private System.ComponentModel.IContainer components = null;
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
#region Component Designer generated code
private void InitializeComponent()
{
this.tabControl = new System.Windows.Forms.TabControl();
this.contentPanel = new System.Windows.Forms.Panel();
this.SuspendLayout();
//
// tabControl
//
this.tabControl.Dock = System.Windows.Forms.DockStyle.Fill;
this.tabControl.Location = new System.Drawing.Point(0, 0);
this.tabControl.Name = "tabControl";
this.tabControl.SelectedIndex = 0;
this.tabControl.Size = new System.Drawing.Size(306, 118);
this.tabControl.TabIndex = 0;
//
// contentPanel
//
this.contentPanel.Dock = System.Windows.Forms.DockStyle.Bottom;
this.contentPanel.Location = new System.Drawing.Point(0, 118);
this.contentPanel.Name = "contentPanel";
this.contentPanel.Size = new System.Drawing.Size(306, 73);
this.contentPanel.TabIndex = 0;
//
// TestUserControl
//
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.Controls.Add(this.tabControl);
this.Controls.Add(this.contentPanel);
this.Name = "TestUserControl";
this.Size = new System.Drawing.Size(306, 191);
this.ResumeLayout(false);
}
#endregion
private System.Windows.Forms.TabControl tabControl;
private System.Windows.Forms.Panel contentPanel;
}
以下是我添加的用于启用设计时支持的源代码:
[Designer(typeof(TestUserControlDesigner))]
public partial class TestUserControl : UserControl
{
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
public TabControl TabControl
{
get { return this.tabControl; }
}
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
public Panel ContentPanel
{
get { return this.contentPanel; }
}
public TestUserControl()
{
InitializeComponent();
}
}
internal class TestUserControlDesigner : ParentControlDesigner
{
public override void Initialize(System.ComponentModel.IComponent component)
{
base.Initialize(component);
EnableDesignMode(
(this.Control as TestUserControl).TabControl, "TabControl");
EnableDesignMode(
(this.Control as TestUserControl).ContentPanel, "ContentPanel");
}
}
我需要做什么才能将控件拖/放到 TabControl 的选项卡页上?
您还必须在现有选项卡页面上启用设计模式:
internal class TestUserControlDesigner : ParentControlDesigner {
public override void Initialize(System.ComponentModel.IComponent component) {
base.Initialize(component);
var ctl = (this.Control as TestUserControl).TabControl as TabControl;
EnableDesignMode(ctl, "TabControl");
foreach (TabPage page in ctl.TabPages) EnableDesignMode(page, page.Name);
EnableDesignMode((this.Control as TestUserControl).ContentPanel, "ContentPanel");
}
}
