We can use the ObjectInTreeView Control in XAML or in code. 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). Dies kann auftreten, wenn die Daten rekursiv sind, z. I figured there would be an easy solution I can google and copy-paste, spending no more than 10 minutes on the whole thing. Es kann vorkommen, dass Sie eine TreeView an eine Datenquelle binden möchten, deren Tiefe nicht bekannt ist. The following example works for any TreeView, regardless of the underlying data model, and searches every TreeViewItem until the object is found. 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.
