Hi

I posted that as a support ticket, but if you have an answer for me, feel frre to give it, thank you very much. I'll paste the answer form the support.


 

I am testing your product. I am trying to make a nested hierarchy inside a radGridView. My code is inspired from both the Getting started documentation and an example you gave about nested hierarchy. Please, see the attached project.

My goal is to show a list of Divisions in a gridView, each division has teams, and each team has some employees.

I have an Employee class:

    public class Employee

    {

        public string FirstName

        {

            get;

            set;

        }

        public string LastName

        {

            get;

            set;

        }

        public int Age

        {

            get;

            set;

        }

        public bool Married

        {

            get;

            set;

        }

    }

A team class who has a collection of employees:

public class Team

    {

        private ObservableCollection<Employee> _empl = new ObservableCollection<Employee>();

        public ObservableCollection<Employee> Empl

        {

            get

            { return _empl; }

            set

            { _empl = value; }

        }

        public int Ident

        {

            get;

            set;

        }

        public string Nom

        {

            get;

            set;

        }

        public int Place

        {

            get;

            set;

        }

    }

A division class who has a list of teams:

    public class Division

    {

        public int Id

        {

            get;

            set;

        }

        public string Name

        {

            get;

            set;

        }

        public List<Team> Teams

        {

            get;

            set;

        }

    }

And a DivisionService class, who creates a collection of divisions, populating each division with some teams and some teams with some employees. Here is an excerpt of the class:

   public class DivisionsService

    {

        public static ObservableCollection<Division> GetDivisions()

        {

ObservableCollection<Division> divisions = new ObservableCollection<Division>();

            Division dA = new Division();

            dA.Name = "Division A";

            dA.Id = 1;

            dA.Teams = new List<Team>();

            Team team1 = new Team();

            team1.Ident = 1;

            team1.Nom = "Team I";

            team1.Place = 1;

            Employee emp01 = new Employee();

            emp01.FirstName = "Maria";

            emp01.LastName = "Anders";

            emp01.Married = true;

            emp01.Age = 24;

            team1.Empl.Add(emp01);

            Employee emp02 = new Employee();

            emp02.FirstName = "Klodia";

            emp02.LastName = "Choufleur";

            emp02.Married = false;

            emp02.Age = 28;

            team1.Empl.Add(emp02);

            dA.Teams.Add(team1);

            Team team2 = new Team();

            team2.Ident = 2;

            team2.Nom = "Team II";

            team2.Place = 2;

            Employee emp03 = new Employee();

            emp03.FirstName = "Jean";

            emp03.LastName = "Bon";

            emp03.Married = true;

            emp03.Age = 44;

            team2.Empl.Add(emp03);

            dA.Teams.Add(team2);

          (code here)

           return divisions;

        }

    }

The XAML creates the gridview and the data template:

<Window x:Class="TestRadGridView.MainWindow"

                           xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

                           xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

                           xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

                           Title="MainWindow" Height="350" Width="525">

             <Grid>

        <telerik:RadGridView x:Name="HierarchicalGridView"

                             AutoGenerateColumns="False"

                             MinHeight="386">

            <telerik:RadGridView.Columns>

                <telerik:GridViewDataColumn DataMemberBinding="{Binding Id}"

                                       Header="Id" />

                <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}"

                                       Header="Name" />

            </telerik:RadGridView.Columns>

            <telerik:RadGridView.HierarchyChildTemplate>

                <DataTemplate>

                    <telerik:RadGridView

                        Name="teamGrid"

                        ShowGroupPanel="False"

                        AutoGenerateColumns="False">

                        <telerik:RadGridView.Columns>

                            <telerik:GridViewDataColumn

                                Header="Id"

                                DataMemberBinding="{Binding Ident}"/>

                            <telerik:GridViewDataColumn

                                Header="Nom"

                                DataMemberBinding="{Binding Nom}"/>

                            <telerik:GridViewDataColumn

                                Header="Place"

                                DataMemberBinding="{Binding Place}"/>

                        </telerik:RadGridView.Columns>

                        <telerik:RadGridView.HierarchyChildTemplate>

                            <DataTemplate>

                                <telerik:RadGridView

                                    Name="employeesGrid"

                                    ShowGroupPanel="False">

                                </telerik:RadGridView>

                            </DataTemplate>

                        </telerik:RadGridView.HierarchyChildTemplate>

                    </telerik:RadGridView>

                </DataTemplate>

            </telerik:RadGridView.HierarchyChildTemplate>

        </telerik:RadGridView>    

    </Grid>

</Window>

And the code behind the data binding and the relations:

       public MainWindow()

        {

            InitializeComponent();

            GridViewTableDefinition TeamsTableDefinition = new GridViewTableDefinition();

            TeamsTableDefinition.Relation = new PropertyRelation("Teams");

            this.HierarchicalGridView.TableDefinition.ChildTableDefinitions.Add(TeamsTableDefinition);

            GridViewTableDefinition emplTableDefinition = new GridViewTableDefinition();

            emplTableDefinition.Relation = new PropertyRelation("empl");

            TeamsTableDefinition.ChildTableDefinitions.Add(emplTableDefinition);

            this.HierarchicalGridView.ItemsSource = DivisionsService.GetDivisions();

        }

So, it does not work: I see the divisions, but there are no teams (and of course I can’t see is there are employees in the teams).

If I delete, in the XAML code, the data template, things are a little better: I see Teams in the divisions, but I do not see Employees in teams. Anyway, I need the data template.

So, what I did wrong?

Could-you too, please, say how to access a selected item in a nested grid? Thank you again.

Cordially

Richard

We would like to expand this so that the selected column of cells moves directly underneath the selection made on the chart.  Is this possible?

Thanks,
Derek
