Support for WPF TreeView ItemTemplate

Hi.



Our dev team uses TreeView ItemTemplate to define custom TreeViewItem with HierarchicalDataTemplate that contains several TextBlock or Picture.

TestComplete object browser detects all those custom item templates. But unfortunately, when we use the Recorded, here is what we see : 



WPFObject("_treeView").ClickItem("|[1]|[0]")



or even wose : 

WPFObject("letreeview").WPFObject("TreeViewItem", "", 5).WPFObject("TreeViewItem", "", 1).WPFObject("TreeViewItem", "", 1).WPFObject("EditableTextBlock", "TEST", 1).Click(6, 7);





I would like to be able to use the same mechanism as with WinFormObject - WinFormObjec("TreeView").Clickitem("|Root|Node|Leaf");

I don't really know if there is something in TestComplete that would let me do so, or if our dev team should uses another kind of templates.



Do you have any idea ?



Regards, 



Guillaume Théraud.

    Hi Guillaume,


     


    Have you tried to manually change the ClickItem method and specify captions of the items you want to click?

    Hi Tanya.



    Thanks for your answer, but indeed, I tried to force TestComplete to use String instead of index. Unfortunately, ClickItem method return undefined. 



    Any other solution in mind ?



    Thanks.



    Guillaume.

    Hello Tanya.



    Well, as I said, my problem comes from the fact that objects I am trying to address are Microsoft WPF Components.

    I now have the same issue with a System.Windows.Controls.Combobox (as you can see in the attached picture).



    I am not sure about your answer, Tanya, but I guess, the Object Mapping tab will not change anything about this.



    I am really surprised that we are the only one facing this kind of issue as, with the WPF applications, the HierarchicalDataTemplate might be use by more than us.



    If anyone has an other option, or solution, that would be great.

    We are also ready to help SmartBart Support Team to help them support this kind of feature in WPF components.



    Regards, 



    Guillaume.

    Hi Guillaume,


     


    How are you filling in these controls? Are you using Data Binding?

    Hi Tanya.



    Indeed we are using Data Binding. Let me explain a bit more how we proceed.

    I attached 3 screenshots : 


    1. 01_GUI_TreeView - A GUI of an application using the DataBinding mechanism.


    2. 02_GUI_TestComplete - An OnScreen Action recorded in a keyword.


    3. 03_ObjectBrowser_TestComplete - The WPFObject (System.Windows.Controls.TreeView) as seen by TestComplete 8 or 9.


    I also joined some source code. The XAML used to defined the treeview behaviour : 



           <TreeView Name="_treeView">

                <TreeView.ItemTemplate>

                    <HierarchicalDataTemplate ItemsSource="{Binding Subordinates}">

                        <StackPanel Orientation="Horizontal">

                            <TextBlock Text="{Binding Path=Name}" />

                            <TextBlock Text="{Binding Path=Age}" />

                        </StackPanel>

                    </HierarchicalDataTemplate>

                </TreeView.ItemTemplate>

            </TreeView>





    The C# class which contains data &colon; 



    public MainWindow()

            {

                InitializeComponent();

                var bob = new Person { Name = "Bob", Age = 34 };

                var sally = new Person { Name = "Sally", Age = 28 };

     

                _treeView.Items.Add(bob);

                _treeView.Items.Add(sally);

                sally.Subordinates.Add(new Person { Name = "Joe", Age = 15 });

            }

     

            public class Person

            {

                public Person()

                {

                    Subordinates = new List<Person>();

                }

     

                public string Name { get; set; }

                public int Age { get; set; }

                public List<Person> Subordinates { get; private set; }

            }





    We are ready to any kind of change in order to make the ClickItem method work properly.



    Regards, 



    Guillaume.

    Hi Guillaume,


     


    As you are using Data Binding, this behavior is expected as in this case, items of a tree view can contain complex objects that cannot be represented by a string value. We have a suggestion to implement support for such complex objects in our DB, and your request has increased its rating. Thanks.


     


    In the meantime, as a workaround, you can create a script routine that will use native methods and properties of the tree view item to get an index of the needed item by its caption and then use the index as an argument of the ClickItem method. You can get access to the collection of tree view items by using the Items or wItems properties of the tree view object. To explore properties and methods of objects in your application, use the Object Browser panel. 


     


    Here is a template script function you can use.




     'VBScript


    ...


      itemIndex = getTreeItemIndex(tree, "Sally28")


      Call tree.ClickItem(itemIndex)


    ...


     


    Function getTreeItemIndex(tree, itemCaption)


      getTreeItemIndex = -1


      For i = 0 To tree.wItemCount - 1


        currentItemCaption = tree.Items.Item(i).??? ' Find the property of an item object containing the caption of the item.


        If itemCaption = currentItemCaption Then


          getTreeItemIndex = i


          Exit For


        End If


      Next  


    End Function

    Hi Tanya.



    Indeed, we are looking forward this kind of support. Thanks.



    Even if we are already using this kind of a workaround on other issues, I was trying to avoid this one here as it prevents us from using the Recorder.



    Anyway, thank you for these answers.



    Regards, 



    Guillaume.

    Hi again, 



    I was wondering what do you mean by :

    " items of a tree view can contain complex objects that cannot be represented by a string value ".





    In this example, it might not be the case, but if this complex object implements ToString() method, It should be able to be represented as a String, and thus, enable TestComplete specific behaviour, right ?



    Does any of you have an example of DataBinding implementation that still enable TestComplete support, so we can see how TestComplete actually proceeds ?



    Regards, 



    Guillaume

    Hi again.


     


    I would like to refresh this thread.


    Indeed, our dev team is using DataBinding more and more often.


     


    I am reluctant to create specific script function in order to support this.


    First, I will loose TestRecorder feature, and I will increase the maintenance of our code.


     


    As Tanya said "As you are using Data Binding, this behavior is expected as in this case, items of a tree view can contain complex objects that cannot be represented by a string value." I am surprised by this argument. Indeed, I cannot see how a WPF.Control.TextBlock could not be represented by a String.



    I would really like to provide our dev team the procedure in order to TestComplete to be able to work with their products. 

    Otherwise, I can not believe there is nothing we can do (appart from create a script) to make this major DotNet feature work with TestComplete.



    Regards, 



    Guillaume.
