There are many samples of creating a WPF TreeView Control and populating it in XAML but in actual use we are much more likely to populate a TreeView Control dynamically from data. Then add a SharedSizeGroup to the ColumnDefinition s that should have the same width across all the treeview items (your first column definition has a fixed width anyway, so its not needed on that):. ![]() Like doing a Raisepropertychanged of the backing Observablecollection(in order to refresh when we add/remove folders) suddenly sends you to the bottom of the treeview, and other fun hijinks.īasically my question is if any of you have had good experiences with alternative implementations? I can see there are indeed alternatives (perhaps not drop-in replacements, but that's fine), but I'd rather see if anybody here has had the same problem and found an implementation they like (instead of me having to try out 5 different implementations before I find one that's decent). This article provides a simple sample of populating a WPF TreeView Control programmatically. In the TreeView control, set Grid.IsSharedSizeScope to true:. The way TreeView was designed to be used is following the MVVM design pattern. This obviously will not scale well, but if just need a quick and dirty solution, you should be able to do this in blend in a few minutes without adding dependencies for external controls / libraries. After trying to help you, you then say that it did work, but you. First you said you couldnt do something, but then provided us with a link to a valid solution in another post. UPDATE > I simply dont understand why you posted this question. There are basically two ways to work with these controls, one that makes dynamically changing trees easy to manage, and one that makes completely static trees trivial to setup. If the added border is the same width for all rows, you will have a view that feels like a treeview with columns. If you still dont understand this, take a look at the Context Menus in WPF page on WPF Tutorial.NET. ![]() I enabled virtualization and while this helps the performance of rendering only what is needed/in view, it gets some really strange behaviours instead. The TreeView in WPF is an extension of ItemsControl. It's not insanely deep of a tree (usually maybe a depth of 4).īut wpf's treeview really chokes on rendering this. But it has given me a neverending stream of headaches.īasically we have a hierarchic structure to represent, about 2000 folders. I have been using the default treeview control in our wpf application.
