Notice in line 28 of Figure 4 that the ItemsSource of the TreeView control is using the static resource with the key of theData as the source of data for the TreeView. I have done a lot of reading about hierarchal data templates and observable collections but cannot seem to make them fit with my requirements (probably due to my lack of experience). Provide your instance of EmployeeTypes with a name using the x:Key attribute, in this example, theData. If I stored the data this way, I would need to add each folder to it's parent folder first (based on the ParentID), then add the reports to the correct folder (based on the FolderID).īeing fairly new to WPF and C# in general, I am not sure if this is the best way or if it would even work. We create two instances of TreeViewItem objects. In TreeViewLoaded, we need to initialize the items within the control. Press tab and they will be added automatically by Visual Studio. Next, add the 'Loaded' and 'SelectedItemChanged' attributes to the TreeView element. I was thinking of having my database table structure as follows: Please begin by dragging a TreeView control to the WPF window. The application will not know how many levels there will be, only that there are 2 types of items, folders, and reports. The treeview needs to have multiple levels like the following: Shows how to bind the selected item of a WPF TreeView using the MVVM pattern - daspn/treeview-with-mvvm. Problem in your solution with dotted lines is that you are using rectangle as a line with width or height set to 1. When testing WPF TreeView controls, you can use properties and methods specific to these controls, as well as properties and methods that TestComplete applies to tested objects, onscreen objects and window objects.I am trying to populate a treeview from a database, but I am not sure the best way to do it. WPF default TreeView is very good, I still want it have lines joint each its child element, like Windows Forms TreeView. If the specified custom control does not fit the control’s type, then it may not properly respond to commands that TestComplete sends, so recording or playing back user actions over the tested control will cause errors. I have searched so many times on this site, but I found no answers to my problem. Once the control is mapped, it gets all the properties, methods and actions specific to the WPF TreeView control. Im trying to bind recursively a Treeview to ObservableCollections. For detailed information, see Object Mapping. TestComplete will retrieve the control’s class name and add it to the selected mapping group automatically. ![]() As an alternative, you can click Add From Screen and select your custom control on screen. If you do not know the control’s name, you can ask the control’s developers, or you can view the control’s ClrFullClassName property in the Object Browser panel. Open your project’s Object Mapping options.Īdd the control’s class name to the WPF Controls | Tree view group. To command TestComplete to recognize your custom controls as Group.) If the plugin is not available, run the TestComplete installation in the Repair mode. If you experience issues when working with the controls, select File > Install Extensions from the TestComplete main menu and check whether the plugin is active. This plugin is installed and enabled automatically as part of the TestComplete Desktop module. Support for the WPF TreeView controls is implemented by the WPF Control Support plugin. You can also command the test engine to recognize custom controls as WPF TreeView controls. By default, this group contains the following items: The control’s class name must be specified in the WPF Controls | Tree view group of your project’s You must have an active license for the TestComplete Desktop module. In order for TestComplete to be able to work with WPF TreeView controls, the following requirements must be met: It provides special properties and methods that let you retrieve the controls data and simulate user actions on the controls (see below). TestComplete can recognize WPF TreeView controls in WPF applications. ![]()
