我正在开发一个可视工作室包来处理一些高级工作项复制方案。我想知道是否有人知道如何重现工作项上使用的树状“区域路径”和“迭代”控件，以便在我的加载项中使用？我正在使用WPF构建我的控件。
答案 0 :(得分：2)
该控件位于Microsoft.TeamFoundation.WorkItemTracking.Controls程序集中。它是WorkItemClassificationControl，但它是“内部”，这意味着你将无法引用它。我还与工作项跟踪客户团队的一位开发人员进行了交谈，他说该控件不是为在Team Explorer（我们的Visual Studio包）之外使用而设计的。
答案 1 :(得分：1)
这是互联网上非常痛苦的比特集合，因为我是WPF的新手，但我重新创建了它。我找到了ComboBox的原始XAML并修改如下：

我还必须在IsDropDownOpen上添加ComboBox属性的行为和一些时髦的bug。
public class BindableSelectedItemBehavior : Behavior<TreeView>
{
public static readonly DependencyProperty SelectedItemProperty =
DependencyProperty.Register("SelectedItem", typeof(object), typeof(BindableSelectedItemBehavior), new UIPropertyMetadata(null, OnSelectedItemChanged));
public object SelectedItem
{
get { return (object)GetValue(SelectedItemProperty); }
set { SetValue(SelectedItemProperty, value); }
}
protected override void OnAttached()
{
base.OnAttached();
this.AssociatedObject.SelectedItemChanged += this.OnTreeViewSelectedItemChanged;
}
protected override void OnDetaching()
{
base.OnDetaching();
if (this.AssociatedObject != null)
{
this.AssociatedObject.SelectedItemChanged += this.OnTreeViewSelectedItemChanged;
}
}
private static void OnSelectedItemChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
{
var item = e.NewValue as TreeViewItem;
if (item != null)
{
item.SetValue(TreeViewItem.IsSelectedProperty, true);
}
}
private void OnTreeViewSelectedItemChanged(object sender, RoutedPropertyChangedEventArgs<object> e)
{
this.SelectedItem = e.NewValue;
var treeView = (TreeView)sender;
var control = (FrameworkElement)treeView.TemplatedParent;
ComboBox combo;
do
{
combo = control as ComboBox;
if (combo != null)
{
break;
}
}
while ((control = (FrameworkElement)control.TemplatedParent) != null);
if (combo == null)
{
return;
}
Dispatcher.BeginInvoke(new Action(() => combo.IsDropDownOpen = false)); // setting in other ways (XAML) wasn't working as expecting
}
}
并在实际控制中
...
<ComboBox Name="area" Style="{StaticResource Tree}"/>
...
<ComboBox Name="iteration" Style="{StaticResource Tree}"/>
和
背后的控制代码 private void UpdateAreasAndIterations(object sender, EventArgs e)
{
if (this.project.SelectedIndex <= 0)
{
this.area.Items.Clear();
this.iteration.Items.Clear();
}
else
{
var project = (Project)this.project.Items[this.project.SelectedIndex];
this.area.ItemsSource = project.AreaRootNodes;
this.iteration.ItemsSource = project.IterationRootNodes;
}
}
