Private TelerikContextMenu ContextMenu Īt the time of writing, when you are using a template you cannot trigger a close of the ContextMenu, you can only close it if you click outside of it (there is an opened feature request for that in our public feedback portal) that contains a workaround. Here is an example of such a configuration - Context menu for a TreeView node Use the oncontextmenu event of the HTML element to show the ContextMenu for the TreeView items itm = context as TreeItem The example below shows a basic TreeView. Because of the use of FolderItem to represent more than one class, multiple object types can share the same definition.You can use the oncontextmenu event of an HTML element in the treeview item template to show the context menu by using the MouseEventArgs.Īs of version 2.27, the TreeView exposes OnItemContextMenu event that you can use to integrate Telerik Context menu for the TreeView nodes. However, I would now like to add ContextMenus in XAML, which are typically specific to the object type the user has clicked on. The answer from that question compiled and ran, but did not actually allow the TreeViewItem to become selected like I wanted. Previously, (In this question) I tried to do this by calling to SetSelectedItem() method from wherever I wanted to allow a TreeViewItem to be selected. The ContextMenu exposes an API to associate the component to any DOM element through the ShowAsync method. I would like to be able to select a TreeViewItem in my program on right-click. I would like to add the ContextMenu component to every item (node) in the TreeView.

Scene scene = (Scene)((MenuItem)sender).DataContext The TreeViewControl can display information in a tree from a self-referential (flat) or hierarchical data structure. They're referenced by HeirarchicalDataTemplates in a TreeView Īnd some example probably-not-really-proper-MVVM code behind: private void deleteScene_Click(object sender, RoutedEventArgs e) This is from a quickie personal project so the code may be a bit messy.Īll my ContextMenu's are in a resource dictionary. Here's an example of a TreeViewItem with a context menu. Question: is there an easy way to get this menu to behave normally? Or do I need to borrow a context menu from WinForms, too? If a given TreeViewItem has no ancestor of type TreeViewItem, then you know it must be a top-level item. The only problem is: the menu doesn't close if you click outside it! It just stays stuck open forever until you either close the app or select one of the items.Īpparently, WPF ContextMenus only work correctly when on a WPF form and not when opened from the Notification area or any other place. If (mouseEvent.Button = )ĬontextMenu menu = (ContextMenu)mainWindow.FindResource("NotifyIconContextMenu") Īll the documentation I can find tells me that menu.IsOpen = true is the correct way to open a context menu in WPF. example, a TextBox control has a ContextMenu control attached to it and it. Var mouseEvent = e as WinForms.MouseEventArgs menu that enables a control to display the functionality that is specific to. NotifyIcon.Click += new EventHandler(NotifyIcon_Click) Īnd the click handler for it is as follows: private void NotifyIcon_Click(object sender, EventArgs e) NotifyIcon.Icon = Īnd initialized in our App.Xaml as follows: private static WinForms.NotifyIcon notifyIcon = null Var notifyIcon = new WinForms.NotifyIcon() (In fact there's a few places where we have to link in WinForms because WPF lacks basic shit, but that's a rant for elsewhere.)Īnyway the notification icon is created as follows: using WinForms = Turns out WPF has no notification icon class, so we end up having to steal one from WinForms anyway. He then left all the hard bits he couldn't figure out to me, a person who hates WPF because it's overcomplicated garbage. Ok, so I had a program that was working perfectly fine in WinForms, and my buddy decided to write the GUI all over again in WPF because the animations are slightly smoother.
