NodeReference() [1/2]

NodeReference ( string relativePath )

inline

Creates a node reference using a relative path.

Parameters

relativePath

Relative path to the node to which you want the reference to point.

Examples

To create a node reference using a relative path:

        public void Execute(PluginCommandParameter parameter)
        {
            // Get the Screens/Screen/RootPage node.
            var rootPage = studio.ActiveProject.GetProjectItem("Screens/Screen/RootPage");
            // In the RootPage node create a Page node named Intro.
            var introPage = studio.ActiveProject.CreateProjectItem<Page>(rootPage.GenerateUniqueChildName("Intro"), rootPage);
            // Set the Default Subpage property of the RootPage node to the Intro node.
            rootPage.Set(Properties.PageHostDefaultSubPage.Name, "Intro");
            // In the RootPage node create a Page node named Main.
            studio.ActiveProject.CreateProjectItem<Page>(rootPage.GenerateUniqueChildName("Main"), rootPage);
            // In the Intro Page node get the first Page Activated trigger.
            var pageActivatedTrigger =
                introPage.Triggers.First(
                    trigger => trigger.Get(Properties.TriggerMessageType) == studio.ActiveProject.MessageTypeLibrary.GetItemByName("Message.Page.Activated"));
            // In the Page Activated trigger create a trigger action, and set:
            // * Trigger Action Type to Dispatch Message Action
            // * Message Type to Navigate To Page
            var navigateToPageAction = pageActivatedTrigger.CreateAction(studio.ActiveProject.TriggerActionTypeLibrary.GetItemByName("Kanzi.DispatchMessageAction"));
            navigateToPageAction.DispatchMessageActionMessageType = studio.ActiveProject.MessageTypeLibrary.GetItemByName("Message.Page.Navigate");
            // Create a node reference using a relative path from the Intro Page node to the Main Page node.
            ProjectItemReference<ExportedPropertyContainerItem> routingTarget = new NodeReference<Page>("../Main");
            // In the Navigate To Page action set Item to relative path that points from the Intro Page node to the Main Page node.
            navigateToPageAction.RoutingTarget = routingTarget;
            // In the Navigate To Page action set Delay to 2000 ms.
            navigateToPageAction.Delay = 2000;
        }

NodeReference() [2/2]

NodeReference ( T targetNode )

inline

Creates a node reference.

Parameters

targetNode

The node to which you want the reference to point.

Examples

To create a node reference:

        public void Execute(PluginCommandParameter parameter)
        {
            // Get the Screens/Screen/RootPage node.
            var rootPage = studio.ActiveProject.GetProjectItem("Screens/Screen/RootPage");
            // In the RootPage node create a Page node named Intro.
            var introPage = studio.ActiveProject.CreateProjectItem<Page>(rootPage.GenerateUniqueChildName("Intro"), rootPage);
            // Set the Default Subpage property of the RootPage node to the Intro node.
            rootPage.Set(Properties.PageHostDefaultSubPage.Name, "Intro");
            // In the RootPage node create a Page node named Main.
            var mainPage = studio.ActiveProject.CreateProjectItem<Page>(rootPage.GenerateUniqueChildName("Main"), rootPage);
            // In the Intro Page node get the first Page Activated trigger.
            var pageActivatedTrigger =
                introPage.Triggers.First(
                    trigger => trigger.Get(Properties.TriggerMessageType) == studio.ActiveProject.MessageTypeLibrary.GetItemByName("Message.Page.Activated"));
            // In the Page Activated trigger create a trigger action, and set:
            // * Trigger Action Type to Dispatch Message Action
            // * Message Type to Navigate To Page
            var navigateToPageAction = pageActivatedTrigger.CreateAction(studio.ActiveProject.TriggerActionTypeLibrary.GetItemByName("Kanzi.DispatchMessageAction"));
            navigateToPageAction.DispatchMessageActionMessageType = studio.ActiveProject.MessageTypeLibrary.GetItemByName("Message.Page.Navigate");
            // Create a node reference that points to the Main Page node.
            ProjectItemReference<ExportedPropertyContainerItem> routingTarget = new NodeReference<Page>(mainPage);
            // In the Navigate To Page action set Item to absolute path that points to the Main Page node.
            navigateToPageAction.RoutingTarget = routingTarget;
            // In the Navigate To Page action set Delay to 2000 ms.
            navigateToPageAction.Delay = 2000;
        }

Member Function Documentation

GetTarget()

T GetTarget ( Node context )

inline

Gets the node to which a relative node reference points.

Parameters

context

The node that you use to resolve the relative path to the target node.

Returns

The node to which a relative node reference points.

Examples

To get the node to which a relative node reference points:

        public void Execute(PluginCommandParameter parameter)
        {
            // Get the Screens/Screen/RootPage node.
            var rootPage = studio.ActiveProject.GetProjectItem("Screens/Screen/RootPage");
            // In the RootPage node create a Page node named Intro.
            var introPage = studio.ActiveProject.CreateProjectItem<Page>(rootPage.GenerateUniqueChildName("Intro"), rootPage);
            // In the RootPage node create a Page node named Main.
            studio.ActiveProject.CreateProjectItem<Page>(rootPage.GenerateUniqueChildName("Main"), rootPage);
            // Create a node reference using a relative path from the Intro Page node to the Main Page node.
            ProjectItemReference<ExportedPropertyContainerItem> routingTarget = new NodeReference<Page>("../Main");
            // Get the target node of the node reference that you created.
            // Use the Intro Page node as the context for resolving the relative path to the Main Page node.
            var target = routingTarget.GetTarget(introPage);
            // Print the absolute path to the target node to the Kanzi Studio Log window.
            studio.Log(target.Path);
        }
