Question

I do not even know where to start with this. I can build a telerik tree that has parents and children, but I cannot figure out how to make it where it is not always symmetric. This is a validation tree so it tells the user error messages. For example, it should look like this:

Object ID (Main Property)
- Must start with a number (Description)
Employee Name (Main Property)
   Employee 1 (SubProperty)
       - Cannot be blank (Description)
   Employee 2 (Subproperty)
       - Cannot be blank (Description)

Any help with this or something that would lead me in the right direction would be helpful. This is my first time working with trees in WPF/C# so please be kind haha.

Edit: because I agree this is very vague:
Attached are images of my code. Since I am going through a virtual machine I had to do screen shots.

ViewModelBase:

ViewModel Cont:

XAML:

ValidationInfo:

Invalid Property:

If there is any other specific code you need to see, please let me know.

Answer 1

This is a bit of a vague question, but a class definition like;

class ValidationNode
{
    bool IsValid { get; }
    object EntityToValidatate { get; set; }
    string ErrorMessage { get; set; }

    ValidationNode Parent { get; set; } 

    IList<ValidationNode> Children { get; set; }
}

Sounds like what you want to start with? Each node can have N child nodes, with some sort of attached validation logic at each step.

No doubt this is not going to completely answer your question, suggest you add more info there.
