Не удается получить текущий активный / выбранный TabITem в Dev Express DxTabControl в WPF

/ 12 февраля 2020

У меня есть приложение WPF, и я пытаюсь автоматизировать его, используя FlaUI . У меня проблема с DxTabControl. Я предоставил Automation IDs на DxTabControl. Я использую DXTabControl.ItemHeaderTemplate для генерации TabItems динамически. Согласно Dev Express Team, DXTabControl.ItemHeaderTemplate не поддерживает AutoamtionPeer, поэтому для изменения поведения по умолчанию была добавлена ​​специальная реализация.

Теперь я могу видеть TabControl и TabItems в Inspect.exe. Теперь мое требование состоит в том, чтобы получить доступ к выбранному в настоящий момент Tabitem и найти CloseButton, используя AutoamtionID, упомянутый в XAML ниже, и закрыть его. Вставить ниже линии снова. Поскольку будет создано несколько TabItems, я не могу получить Текущий active/Selected TabItem.

XAML ниже

Мой FlaUI подход к поиску элементов управления ниже 

public IMainWindow ConfirmCreatedView()
        {
            _logger.Info("Checking the newly created View on the screen");
            //Apoorv: Need to find TabItem here
            _controlAction.Highlight(ViewsTabControl); // This highlights the TabControl- Works
            int NumberOfActiveTabs = ViewsTabControl.TabItems.Length; // This gives me no of TabItems


          TabItem SelectedTab=  ViewsTabControl.SelectedTabItem as TabItem; // Gives me Null here
            var newTab = ViewsTabControl.SelectedTabItemIndex ; // Give me -1 here


            _controlAction.Highlight(ViewsTabControl.TabItems[2]); // Works. It highlights the TabItem at position 2

            _controlAction.ClickWait<TabItem>(ViewsTabControl.TabItems[2]); // This goes and clicks the tab item 

            TabItem SelectedTabs = ViewsTabControl.SelectedTabItem as TabItem;
            var check = ViewsTabControl.TabItems[2].FindAllChildren();
            // TabItem ti = ViewsTabControl.SelectedItem as TabItem;
            //_controlAction.Highlight()



                _controlAction.Highlight(CloseCurrentView); // highlights the close button atTabItem[0]
                _controlAction.Click<Button>(CloseCurrentView); // closes it

                      return this;
        }

Я использую FlaUI, чтобы найти TabControl, используя AutomationID, как показано ниже 

 private Tab ViewsTabControl => _uiAutomation.FindElement("ViewsParentTabControl", Automation.FindBy.Id).AsTab();
        private TabItem ViewsTabItem => _uiAutomation.FindElement("DXTabItem", Automation.FindBy.Id).AsTabItem();

Я хотел бы найти на данный момент активный TabItem на основе на индекс и затем go и нажмите кнопку закрытия, автоматизировав его. 

TabItem SelectedTab=  ViewsTabControl.SelectedTabItem as TabItem; // Gives me Null here
            var newTab = ViewsTabControl.SelectedTabItemIndex ; // Give me -1 here

DevEXpress не создавать automation peers для элементов управления в ItemHeaderTemplate. Для обеспечения этой функциональности необходимо будет использовать custom automation peer. Например, я использовал следующий класс для тестирования: 

public class DXTabItemAutomationPeerEx : DXTabItemAutomationPeer, ISelectionItemProvider {
    private DXTabItem TabItem => base.Owner as DXTabItem;
    private DXTabControl TabControl => TabItem.With((DXTabItem x) => x.Owner);
    public DXTabItemAutomationPeerEx(DXTabItem ownerCore) : base(ownerCore) { }
    protected override List<AutomationPeer> GetChildrenCore() {
        List<AutomationPeer> children = base.GetChildrenCore();
        foreach (var button in LayoutTreeHelper.GetVisualChildren(Owner).OfType<Button>())
            children.Add(new ButtonAutomationPeer(button));
        return children;
    }
    bool ISelectionItemProvider.IsSelected { get {
            if (TabControl != null) {
                return TabControl.SelectedContainer == TabItem;
            }
            return false;
        } 
    }
}

После добавления этого кода внутри моего MainPage.Xaml.cs я добавил static constructor к register it 

static MainWindow() {
    NavigationAutomationPeersCreator.Default.RegisterObject(typeof(DXTabItem), typeof(DXTabItemAutomationPeerEx), owner => new DXTabItemAutomationPeerEx((DXTabItem)owner));
}

опубликовать это, эти строки работают как очарование 

TabItem CurrentTab = ViewsTabControl.SelectedTabItem as TabItem;
var Children = ViewsTabControl.FindAllChildren(); 
foreach (var child in Children) {
    var subChildren = child.FindAllChildren();
}

Это не TabItem, это DXTabItem. Это тип, который вы должны использовать. 

DXTabItem SelectedTab = ViewsTabControl.SelectedTabItem as DXTabItem;
