            </ListBox>
        </controls:PanoramaItem>**

这是.xmal Part。但是我必须在c＃中这样做。然后请帮我解决这个问题。

Answer 1

ListBox listBox = new ListBox();
listBox.Margin = new Thickness(0, 0, -12, 0);
listBox.SetBinding(ListBox.ItemsSourceProperty, new Binding("Items"))

CreateItemTemplate(listBox);

PanoramaItem pi = new PanoramaItem();
pi.Header = "first item";
pi.Content = listBox;

在实施CreateItemTemplate时，您有两个选择，要么以编程方式创建DataTemplate，要么在ResourceDictionary中创建资源并使用该资源。后者是迄今为止最简单，最好的方式。

以编程方式查看How to define a DataTemplate in code?

要使用资源，您可以这样

public void CreateItemTemplate(ListBox listBox)
{
    object myDataTemplate = FindResource("myDataTemplateResource"); // This only works if the resource is available in the scope of your control. E.g. is defined in MyControl.Resources
    listBox.SetResourceReference(ListBox.ItemTemplateProperty, myDataTemplate);
}

如何在c＃中动态创建PanoramaItem控件？
