我在C#代码中创建一个TabControl。我将其ItemsSource绑定到集合并设置边距。 出于某种原因,设置其DisplayMemberPath将无法正常工作。在C中设置TabControl的DisplayMemberPath#
_tabControl = new TabControl();
_tabControl.Margin = new Thickness(5);
_tabControl.DisplayMemberPath = "Header";
_tabControl.SetBinding(ItemsControl.ItemsSourceProperty, itemsSourceBinding);
集合中的每个项目都有一个名为“Header”的属性。
为什么这不起作用?

编辑: 这里是所有相关代码:
public partial class VariationGroupPreviewOptionsView
{
public string Header { get; set; }
public VariationGroupPreviewOptionsView()
{
InitializeComponent();
DataContext = new VariationGroupPreviewOptionsViewModel();
}
}
private void OptionsCommandExecute()
{
var dlg = new OptionsDialog();
dlg.ItemsSource = new List<ContentControl>() {new VariationGroupPreviewOptionsView(){Header = "Test"}};
dlg.ShowDialog();
}
public class OptionsDialog : Dialog
{
public static readonly DependencyProperty ItemsSourceProperty =
DependencyProperty.Register("ItemsSource", typeof (IEnumerable), typeof (OptionsDialog), new PropertyMetadata(default(IEnumerable)));
public IEnumerable ItemsSource
{
get { return (IEnumerable) GetValue(ItemsSourceProperty); }
set { SetValue(ItemsSourceProperty, value); }
}
private readonly TabControl _tabControl;
public OptionsDialog()
{
DataContext = this;
var itemsSourceBinding = new Binding();
itemsSourceBinding.Path = new PropertyPath("ItemsSource");
_tabControl = new TabControl();
_tabControl.Margin = new Thickness(5);
_tabControl.DisplayMemberPath = "Header";
_tabControl.SetBinding(ItemsControl.ItemsSourceProperty, itemsSourceBinding);
var recRectangle = new Rectangle();
recRectangle.Margin = new Thickness(5);
recRectangle.Effect = (Effect)FindResource("MainDropShadowEffect");
recRectangle.Fill = (Brush)FindResource("PanelBackgroundBrush");
var grdGrid = new Grid();
grdGrid.Children.Add(recRectangle);
grdGrid.Children.Add(_tabControl);
DialogContent = grdGrid;
}
}
请描述“不起作用”。 – 2012-04-02 08:54:26
