We can use the ObjectInTreeView Control in XAML or in code. Private static string GetValueAsString( object value) KeyValueNode.Value = GetValueAsString(kv.Value) Äictionary dictionary = (Dictionary)item Private static void BuildTree( object item, TreeNode node) Var serialized = (obj) Äictionary 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.Ä«y 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 â Go over the objectâs properties and fields with reflection, turning them into a âtree-likeâ data structure. You probably know it and use it every day â Yes, itâs Newtonsoft.Json. Luckily, a library that does exactly that, already exists. You might have virtual properties, abstract classes and generics. It needs a Children property of type ObservableCollection.It needs these three things: It must implement INotifyPropertåhanged. Create a view model class (I've called it CheckableItem here) for your tree view item data. And so on.Īs a matter of fact, going over the properties and fields of an object with Reflection is not that easy. This is remarkably straightforward to do, once you know how. 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 werenât what I wanted or simply didnât work.Īfter some research and coding, spending much more than the intended 10 minutes, I came up with a solution Iâm 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 objectâs properties and fields. The debuggerâs data tip control is exactly what I needed. NET objectâs 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.
