我想在点击按钮后添加一个TabPage。我遇到的困难是我有一个带有按钮的UserControl，而tabpage是一个usercontrol，我想用TabControl添加到现有的UserControl。
这是我要添加的标签的Usercontrol：

使用btnAddWorker我想添加tabPage。
如何使用button_click事件将tabPage添加到带有TabControl的UserControl？
感谢所有有用的答案

托比编辑：
嗨，直到现在还没有运行。我需要一点提示。
这是UserControl A中的委托：
public delegate void tabWork(TabControl tabsWork);
这里我得到了UserControl A中的按钮和addTab方法：
private void btnAddWorker_Click(object sender, EventArgs e)
{
addTab(tabsTravel);
}
static void addTab(TabControl tabsTravel)
{
string title = "worker " + (tabsTravel.TabCount + 1).ToString();
TabPage travel = new TabPage();
tabWork work;
tabsTravel.TabPages.Add(travel);
travel.Text = title;
travel.BackColor = Color.White;
travel.Controls.Add(new TabsTravel());
work = new tabWork(Page3.addTab);
}
在这里我得到了UserControl B中的addTab方法：
public static void addTab(TabControl tabsWork)
{
TabsWork work = new TabsWork();
TabPage Tabwork = new TabPage();
string title = "worker " + (tabsWork.TabCount + 1).ToString();
tabsWork.TabPages.Add(Tabwork);
Tabwork.Text = title;
Tabwork.BackColor = Color.White;
Tabwork.Controls.Add(new TabsWork());
}
但从不调用UserControl B中的addTab。
我该如何解决这个问题？

您应该创建一个事件，通知其他用户控件创建/添加另一个传递沿着对象的选项卡，其中包含您希望在其他userControl中可用的信息
