I am using Telerik UI for Winforms version 2022.1.118.40
I am trying to bind a treeview to a list of object-related data, but only the root nodes are displayed.
My object-related data looks like this:
public class MyRootObject
{
public string Name {get; set;}
public List<MyChildObject> ChildObjects {get; set;}
}
public class MyChildObject
{
public string Name {get; set;}
}My treeview is set up like this:
var myRootObjects = new List<MyRootObject>()
{
new MyRootObject()
{
Name = "RootName",
ChildObjects = new List<MyChildObject>()
{
Name = "ChildName"
}
}
}
MyTreeView.DataSource = myRootObjects;
MyTreeView.ChildMember = "ChildObjects";
I have tried different ways of setting the 'ChildMember' property, as per documentation ( https://docs.telerik.com/devtools/winforms/controls/treeview/data-binding/binding-to-object-relational-data ), such as 'myrootObjects\\ChildObjects', but I can not get the child objects to be displayed.
How do I get the child objects to be displayed?

Hello Navid,
The ChildMember needs to start with the type of the main object. Then you can list the collection properties. The DisplayMember property needs to list the properties which will be used on each level. I have extended your code to show one more level of hierarchy. You can find the sample project attached to this reply.
I hope the attached project will help you to understand how to set up the RadTreeView hierarchy.
