If you want to add a new Page, as opposed to a UserControl, you can create a new Frameobject and place the page in there.
如果您想添加一个 new Page，而不是一个UserControl，您可以创建一个新Frame对象并将页面放在那里。
if (ISFirstRender)
{
TabItem tabitem = new TabItem();
tabitem.Header = "Tab 3";
Frame tabFrame = new Frame();
Page1 page1 = new Page1();
tabFrame.Content = page1;
tabitem.Content = tabFrame;
pan1.Items.Add(tabitem);
ISFirstRender = false;
}

You can add user controls to the TabControl. So go to the add new items and select the user control and make what you want (like what you have in the page). Then add an instance of that user control to the TabControl.
您可以将用户控件添加到TabControl. 因此，转到添加新项目并选择用户控件并制作您想要的内容（例如您在页面中拥有的内容）。然后将该用户控件的一个实例添加到TabControl.
protected override void OnRender(DrawingContext drawingContext)
{
if (ISFirstRender)
{
TabItem tabitem = new TabItem();
tabitem.Header = "Tab 3";
pan1.Items.Add(tabitem);
MyUserControl userControl = new MyUserControl();
tabitem.Content = userControl;
ISFirstRender = false;
}
base.OnRender(drawingContext);
}
