以编程方式将ItemsPanelTemplate网格位置设置为StatusBarItem

StatusBar statusBar = new StatusBar();

ItemsControl itemsControl = new ItemsControl();
StatusBarItem statusBaritem = new StatusBarItem();

// 创建ItemsPanelTemplate并设置为网格布局
ItemsPanelTemplate itemsPanelTemplate = new ItemsPanelTemplate(new FrameworkElementFactory(typeof(Grid)));
itemsControl.ItemsPanel = itemsPanelTemplate;

// 创建子项并设置网格位置
Button button1 = new Button();
Grid.SetColumn(button1, 0);
Grid.SetRow(button1, 0);

Button button2 = new Button();
Grid.SetColumn(button2, 1);
Grid.SetRow(button2, 0);

// 将子项添加到ItemsControl中
itemsControl.Items.Add(button1);
itemsControl.Items.Add(button2);

// 将ItemsControl添加到StatusBarItem中
statusBaritem.Content = itemsControl;

// 将StatusBarItem添加到StatusBar中
statusBar.Items.Add(statusBaritem);
