Granted, at the end of the day, it still has a tree data structure consisting of TreeViewItem objects, but the similarities end there. The WPF TreeView control is very different. WinForms should have a Tree control instead of a TreeView control. By the same reasoning, we should call the Menu a MenuView and the ComboBox a ComboBoxView, but that is not the case. One could argue that the WinForms TreeView control’s name is a misnomer, because it can only show its own TreeNodes. You create a tree data structure in the control, where each node in the tree is of type TreeNode, and the control renders those nodes. The WinForms TreeView control is not really providing a “view” of a tree: it is the tree. After a while, I got used to the name and never gave it much thought, until now. NET 1.0 era, I don’t think any other control had the word “View” tacked onto the end of its name, except for ListView. Why not call it the Tree control? Why did they add the word “View” to the end? At the time, the. When I first started learning about Windows Forms, I thought the TreeView control had a strange name. My recent article about it, which, by the way, is my wedding gift to Sacha Barber, discusses how the ideal way of working with a TreeView is to bind it to a ViewModel, and then program against the ViewModel. We can use the ObjectInTreeView Control in XAML or in code.I have been thinking a lot about the WPF TreeView control lately. Private static string GetValueAsString( object value) KeyValueNode.Value = GetValueAsString(kv.Value) ĭictionary dictionary = (Dictionary)item Private static void BuildTree( object item, TreeNode node) Var serialized = (obj) ĭictionary dic = jss.Deserialize>(serialized) JavaScriptSerializer jss = new JavaScriptSerializer() Public static TreeNode CreateTree( object obj) Public partial class ObjectInTreeView : UserControl The WPF Control displaying the tree will be: (Which showed how to display JSON in a WinForms tree view) for pointing me in the right direction.īy the way, we can use the same solution to visualize a JSON document in a WPF TreeView. Once in JSON format, we can use JavaScriptSerializer (in ) to deserialize the JSON and get a data structure we can easily iterate over and populate the tree view. Serializing an object to JSON will do exactly what we need – Go over the object’s properties and fields with reflection, turning them into a “tree-like” data structure. You probably know it and use it every day – Yes, it’s Newtonsoft.Json. Luckily, a library that does exactly that, already exists. You might have virtual properties, abstract classes and generics. And so on.Īs a matter of fact, going over the properties and fields of an object with Reflection is not that easy. Then, we will need to go to the children of each of those properties and add them as well. To do that, we will need to go over each property of the object and add it to the tree. Even though I found some similar solutions, they weren’t what I wanted or simply didn’t work.Īfter some research and coding, spending much more than the intended 10 minutes, I came up with a solution I’m pretty pretty happy with (*self pat on the back). I figured there would be an easy solution I can google and copy-paste, spending no more than 10 minutes on the whole thing. NET object, and the result should be a tree view displaying the object’s properties and fields. The debugger’s data tip control is exactly what I needed. NET object’s properties in an expandable tree view? This is something we constantly use inside the Visual Studio debugger: I recently encountered an interesting challenge: How to display a.
