<button @contextmenu=”handler($event)”>r-click</button> methods : { handler: function(e) { //do stuff e.preventDefault(); } } @contextmenu will do the trick. The preventDefault is to avoid showing the default context menu. Shorter, as indincated in the comment : <button @contextmenu.prevent=”handler”>r-click</button> Now the prevent modifier takes care preventing default behaviour. Edit: For this to work with vue components, add … Read more
You can set ItemContainerStyle and use IsExpanded property. <Page xmlns=”http://schemas.microsoft.com/winfx/2006/xaml/presentation” xmlns:x=”http://schemas.microsoft.com/winfx/2006/xaml”> <Grid> <TreeView> <TreeView.ItemContainerStyle> <Style TargetType=”{x:Type TreeViewItem}”> <Setter Property=”IsExpanded” Value=”True”/> </Style> </TreeView.ItemContainerStyle> <TreeViewItem Header=”Header 1″> <TreeViewItem Header=”Sub Item 1″/> </TreeViewItem> <TreeViewItem Header=”Header 2″> <TreeViewItem Header=”Sub Item 2″/> </TreeViewItem> </TreeView> </Grid> </Page> If you need to do this from code, you can write viewmodel for your … Read more
I have a variation on SoMoS implementation that uses an attached property declared on a derivation of the base TreeView control to track the selection state of the TreeViewItems. This keeps the selection tracking on the TreeViewItem element itself, and off of the model object being presented by the tree-view. This is the new TreeView … Read more
In Windows: Expand all all in project explorer is Shift+Numpad * (multiplty), as mentioned before. Collapse all in project explorer is Ctrl+Shift+Numpad – (subtract). Alternatively, you can just jam on the right arrow to expand to the bottom of a selected tree, or jam on the left arrow to collapse back up to the top. … Read more
You’re pulling the library from the virtual-scroll-demo-branch branch: ‘ngx-tree’: ‘https://rawgit.com/e-cloud/ngx-tree/virtual-scroll-demo-branch/src/lib’, That branch is 105 commits behind master. It incorrectly sets margin-top on one of the inner elements. This is fixed in newer versions. Edit: The developer actually referenced this Stack Overflow question in their commit message.
I found this Post when searching through the web because I am facing the exact same problem. However, appending a white space to the end of the node was not an option, and I found an alternative way that seems to fix the issue. After setting my node font Bold, all I need to do … Read more
Adding to @Sheridan’s answer This isn’t a 100% accurate but should get you pretty close (it’s using the colors from GridView which is pretty close to Windows Explorer) <TreeView …> <TreeView.Resources> <LinearGradientBrush x:Key=”{x:Static SystemColors.HighlightBrushKey}” EndPoint=”0,1″ StartPoint=”0,0″> <GradientStop Color=”#FFD9F4FF” Offset=”0″/> <GradientStop Color=”#FF9BDDFB” Offset=”1″/> </LinearGradientBrush> <LinearGradientBrush x:Key=”{x:Static SystemColors.ControlBrushKey}” EndPoint=”0,1″ StartPoint=”0,0″> <GradientStop Color=”#FFEEEDED” Offset=”0″/> <GradientStop Color=”#FFDDDDDD” Offset=”1″/> </LinearGradientBrush> … Read more

I found this one in the comments to the Code Project article “WPF TreeView Selection” http://www.codeproject.com/KB/WPF/TreeView_SelectionWPF.aspx by DaWanderer. It was posted by Kenrae on Nov 25 2008. This worked great for me. Thanks Kenrae! Here is his … Read more
A HierarchicalDataTemplate is a way of saying ‘this is how you render this type of object and here is a property that can be probed to find the child nodes under this object’ Therefore you need a single property that returns the ‘children’ of this node. e.g. (If you can’t make both Group and Entry … Read more
You can add a mouse click event to the TreeView, then select the correct node using GetNodeAt given the mouse coordinates provided by the MouseEventArgs. void treeView1MouseUp(object sender, MouseEventArgs e) { if(e.Button == MouseButtons.Right) { // Select the clicked node treeView1.SelectedNode = treeView1.GetNodeAt(e.X, e.Y); if(treeView1.SelectedNode != null) { myContextMenuStrip.Show(treeView1, e.Location); } } }
