Transform a RadTreeView into a RadTreeListView or RadGridView

[Andreea]

Hello, 

I am using a RadTreeView component in a WPF application that looks like in the following photo. The hierarchy is: a Category can contain a list of SubCategories and a SubCategory contains a List of Activities that have some properties. I would like to transform my RadTreeView into a RadTreeListView or RadGridVew in order to beneficiate from SelectionUnit property and the navigation between cells from the keyboard but I could not find anything that meets by needs:

a component with cells only on the last level of the hierarchy, to be able to select a cell and edit it  and, if possible, to have a tabular header with details from the last level of the hirarchy.

 

Thank you!

Hi Andreea. 

You can examine the examples for the GridVIew in our demo application. The Custom Grouping example looks quite similar. 

In addition, our SDK repository contains many examples as well:  telerik/xaml-sdk: The XAML SDK is an easy-to-use infrastructure with 1000+ developer focused examples for most of the Telerik WPF and Silverlight controls.

I wanted to ask you to share an example of how your data hierarchy is organized. This is important since it will give us direction about the most suitable approach. 

I am looking forward to your reply.

Thank you very much for your quick response!

This is my hierarchy. "Value1", "Value2".. from the photo are actually Activity's property (Name, NoPerYear,StandardService,Unit, StandardWorkload, CalculatedRequirement)

public partial class Staff : ObservableObject
{
    public int Id { get; set; }
    public string Name { get; set; };
    public int Type { get; set; }

    [ObservableProperty]
    private List<StaffCategory> staffCategories = new List<StaffCategory>();
}

public partial class StaffCategory : ObservableObject
{
    public int Id { get; set; }
    public string Name { get; set; };
    public bool IsSelected { get; set; }


    [ObservableProperty]
    private List<Activity> children = new List<Activity>();

}

 public partial class Activity : ObservableObject
 {
     public int Id { get; set; }
     public string Name { get; set; };

     [ObservableProperty]
     private double? noPerYear;
     [ObservableProperty]
     private double? standardService;
     [ObservableProperty]
     private Unit unit = new Unit();
     [ObservableProperty]
     private double standardWorkload = 0;
     [ObservableProperty]
     private double calculatedRequirement = 0;
 
}

public class Unit
{
    public int Id { get; set; }
    public string Name { get; set; };
}

 

I really appreciate you effort and I am looking forword to your responde. Please let me know if is something I can provide more.

Hi Andreea, 

A possible solution is to use the RowDetails template which will contain another grid view with another row details template.

I have attached a sample project that shows this.

Let me know if you have additional questions.

Hi Dimitar,

Thank you for you help. This solution is not exactly suitable for me because I want to have only one grid header that will be matched with children values, not a nested grid view with individual headers for every child. I think what works for me is, like you said above, the Custom Grouping solution.

 Thanks a lot for effort and interest!
