TreeView Multi Colonnes WPF 4

Version imprimable

Bonjour tout le monde,

Je me permets de venir vous déranger car j'ai un problème dont je n'arrive pas à trouver la solution.
J'ai récupéré un sample me permettant de faire un treeview multicolonne.
Le problème est que j'aimerais binder une ObservableCollection mais que je n'y arrive pas :/
Je suis un débutant et je galère vraiment....

Donc en gros j'ai un fichier de ressources Generic.xaml avec :

                                    Width="16" Height="16"
                                    BorderThickness="1" BorderBrush="DarkGray"/>
                            <!--Display the brush-->
                            <TextBlock Text="{Binding Brush}"/>
                        </StackPanel>
                    </DataTemplate>
                </GridViewColumn.CellTemplate>
            </GridViewColumn>
        </local:TreeListView.Columns>
        <!--Create some sample data-->
        <MaterialGroup>
            <MaterialGroup>
                <DiffuseMaterial Brush="Blue"/>

            <EmissiveMaterial Brush="AliceBlue"/>
        </MaterialGroup>
    </local:TreeListView>
</Window>

Je suis vraiment désolé pour le gros "paté" mais je craque la :cry:

Faut enlever le <MaterialGroup> du treeview, et binder vers ta collection. Exemple :

Code:

 public partial class MainWindow
    {
        public ObservableCollection<Data> TreeViewSource { get; set; }
 
        public MainWindow()
        {
 
            TreeViewSource = new ObservableCollection<Data> { new Data { Nom = "Niveau 1", Brush = new SolidColorBrush(Colors.Blue), Children = new ObservableCollection<Data> { new Data { Nom = "Niveau 2 (1)", Brush = new SolidColorBrush(Colors.White) }, new Data { Nom = "Niveau 2 (1)", Brush = new SolidColorBrush(Colors.Red) } } } };
 
            this.DataContext = this;
 
            InitializeComponent();
        }
    }
 
 
    public class Data
    {
        public string Nom { get; set; }
 
        public SolidColorBrush Brush { get; set; }
 
        public ObservableCollection<Data> Children { get; set; }
    }

Et le XAML (J'ai enlevé les MaterialGroup et mis le ItemSource pour le binding ):

J'ai essayé d'utiliser un treeview sans multi colonnes tout simple via ce code :

Code:

11
12

<Window x:Class="WpfApplication1.Tree"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Tree" Height="481" Width="760">
    <TreeView ItemsSource="{Binding ARAMCollection}" Height="369" Width="676" >
        <TreeView.ItemTemplate>
            <HierarchicalDataTemplate ItemsSource="{Binding PlayerName}">
                <TextBlock FontWeight="Bold" Text="{Binding}" />            
            </HierarchicalDataTemplate>
        </TreeView.ItemTemplate>
    </TreeView>
</Window>

Et malheureusement je n'obtiens rien :/ ma fenêtre est vide.
Ma classe fonctionne car je l'utilise avec une ListView et je n'ai aucun problème d'où mon incompréhension :/

Le datacontext est bien mis? PlayerName est bien une liste?

Oui le DataContext est mis.
PlayerName correspond au champs "Name" de votre exemple dans la Class Data
Code:

1 2 3 4 5 6 7 8 9 10 public partial class Tree : Window { public Tree() { UTILS.OnlineCollection = UTILS.ARAMCollection; this.DataContext = this; InitializeComponent(); } }
La classe UTILS contient la déclaration des Collection OnlineCollection et ARAMCollection. ARAMCollection est remplie dans cette classe UTILS

Ma classe Player se trouvant dans un fichier séparé :
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 public class Player { private string _PlayerName; private string _ScorePlayer; public string PlayerName { get { return _PlayerName; } set { _PlayerName = value; } } public string ScorePlayer { get { return _ScorePlayer; } set { _ScorePlayer = value; } } public Ban(string PN, string SP) { _PlayerName = PN; _ScorePlayer = SP; } }
Ce que je souhaite dans mon treeview :

Citation:

Colonne1_______Colonne2_______________Colonne3
PlayerName1
-------------- ScorePlayer1 ------- Type Collection(ARAM ou Online)
-------------- ScorePlayer1 ------- Type Collection(ARAM ou Online)
-------------- ScorePlayer1 ------- Type Collection(ARAM ou Online)
PlayerName2
-------------- ScorePlayer2 ------- Type Collection(ARAM ou Online)
-------------- ScorePlayer2 ------- Type Collection(ARAM ou Online)
-------------- ScorePlayer2 ------- Type Collection(ARAM ou Online)

J'éspère que c'est peu plus claire :mouarf: Je pensais pas que je galérerais autant étant donné que j'ai pas eu de prob pour exploiter mes collections avant une listview :/

Bon j'obtiens enfin quelque chose mais pas vraiment ce que je veux :(
En fait j'obtiens :
- WpfApplication1.Player
P
L
A
Y
E
R
N
A
M
E
1
- WpfApplication1.Player
P
L
A
Y
E
R
N
A
M
E
2
- WpfApplication1.Player.....

Donc il m'écrit ma Class alors que je veux le champ PlayerName
et le champs PlayerName est écrit verticalement :mrgreen:

Pas sûr exactement de ce que tu veux dans la 3eme colonne. Si c'est juste une donnée "plate" (pas de collection), ce que tu cherches est peut-etre plutot une ListView groupée sur le nom du joueur.

En attendant, voila quelque chose qui correspond à ce que tu cherches en TreeView. L'astuce est d'utiliser un DataTemplateSelector selon qu'on soit sur un type Player, ou un type string (pour le score):
La structure Player

Code:

1
2
3
4
5
6
7
 
    public class Player
    {
        public string PlayerName { get; set; }
 
        public ObservableCollection<string> Score { get; set; }
    }

Le DataTemplateSelector :

Code:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
 
  public class ScoreTemplateSelector : DataTemplateSelector
    {
        public override DataTemplate SelectTemplate(object item, DependencyObject container)
        {
            var element = container as FrameworkElement;
 
            if ((element == null) || (item == null))
                return null;
 
            if (item is Player)
            {
                return element.FindResource("EmptyTemplate") as DataTemplate;
            }
            if (item is string)
            {
                return element.FindResource("ScoreTemplate") as DataTemplate;
            }
 
            return null;
        }
    }

Et le XAML :

Code:

                        ItemsSource="{Binding TreeViewSource}">
        <local:TreeListView.Resources>
            <DataTemplate x:Key="ScoreTemplate">
                <!--Display the size of the DataElement-->

                            <!--The Expander Button (can be used in any column (typically the first one))-->
                            <local:TreeListViewExpander/>
                            <!--Display the name of the DataElement-->
                            <TextBlock Text="{Binding PlayerName}" />
                        </StackPanel>
                    </DataTemplate>
                </GridViewColumn.CellTemplate>
            </GridViewColumn>
            <!--Create a second column containing the number of children.-->
            <GridViewColumn Header="Score"
                            Width="100"
                            CellTemplateSelector="{StaticResource ScoreTemplateSelector}">
 
            </GridViewColumn>
            <!--Create a third column containing the brush of the material.-->
            <GridViewColumn Header="Class" Width="100">
                <GridViewColumn.CellTemplate>
                    <DataTemplate>
                        <StackPanel Orientation="Horizontal">
                            <!--Border showing the actual color-->
                            <!--Display the brush-->
                            <!--<TextBlock Text="{Binding}"/>-->
                        </StackPanel>
                    </DataTemplate>
                </GridViewColumn.CellTemplate>
            </GridViewColumn>
        </local:TreeListView.Columns>
    </local:TreeListView>

Je n'ai rien mis en 3ème colonne, car comme je l'ai dit je ne suis pas sûr de ce qu'il faut mettre.

Oui ce sont des données plates, en fait je voulais un TreeView question d'esthétisme concernant la hiérarchie.
J'ai juste 2 collections avec pour chacune d'elles 3 champs : PlayerName(string), ScorePlayer(String), CollectionType(String)

J'ai testé avec un DataTemplateSelector et cela fonctionne enfin :)
Malheureusement, si j'utilise le code suivant :

Code:

1
2
3
4
5
6
7
8
9
10
11
12
 
public ObservableCollection<TreeCollection> OnlineCollection = new ObservableCollection<TreeCollection>();
 
public MainWin()
{
 
OnlineCollection.Add(new TreeCollection{PlayerName = "Infra",Children = new ObservableCollection<TreeCollection> { new TreeCollection{ PlayerName = "Player1", BanReason = "Leaver", ListTyp = "ARAM"},
new TreeCollection { PlayerName = "Player2", BanReason = "AFK", ListTyp = "ARAM"}, new TreeCollection { PlayerName = "Player3", BanReason = "Selection Leave", ListTyp = "ARAM"}}});
this.DataContext = this;            
InitializeComponent();
 
}

au lieu de :

Code:

1
2
3
4
5
6
7
8
9
10
11
12
 
public ObservableCollection<TreeCollection> OnlineCollection { get; set; }
 
public MainWin()
{
 
OnlineCollection = new ObservableCollection<TreeCollection> { new TreeCollection { PlayerName = "Infra", Children = new ObservableCollection<TreeCollection> { new TreeCollection{ PlayerName = "Player1", BanReason = "Leaver", ListTyp = "ARAM"},
new TreeCollection { PlayerName = "Player2", BanReason = "AFK", ListTyp = "ARAM"}, new TreeCollection { PlayerName = "Player3", BanReason = "Selection Leave", ListTyp = "ARAM" } } } };
this.DataContext = this;            
InitializeComponent();
 
}

mon treeview ne fonctionne plus :/

13/11/2011, 08h28
GuruuMeditation

C'est parce que dans l'exemple qui ne fonctionne pas, OnlineCollection n'est pas une propriété (il n'a pas de "get;set;") mais un champ. Et pour le binding, c'est pas bon.
13/11/2011, 14h26
mso54

Oui oui je sais mais bon j'ai essayé d'ajouter plusieurs données via la propriété et il ne garde que la dernière

J'ai bien essayé la méthode traditionnelle d'ajout de noeud mais sans succés. Après, j'ai peut être merdé quelque part ^^

Code:

1
2
3
4
5
6
 
TreeViewItem newChild = new TreeViewItem();
OnlineCollection = new ObservableCollection<TreeCollection> { new TreeCollection { PlayerName = "Infra", Children = new ObservableCollection<TreeCollection> { new TreeCollection{ PlayerName = "Player1", BanReason = "Leaver", ListTyp = "ARAM"},
new TreeCollection { PlayerName = "Player2", BanReason = "AFK", ListTyp = "ARAM"}, new TreeCollection { PlayerName = "Player3", BanReason = "Selection Leave", ListTyp = "ARAM" } } } };
newChild.Header(OnlineCollection);
TreeView1.Items.add(newChild);

15/11/2011, 17h21

essaye avec :
Code:

1 2 newChild.ItemsSource = OnlineCollection;

Arghhh ca passe pas :(

Citation:

[System.NullReferenceException] = {"La référence d'objet n'est pas définie à une instance d'un objet."}

sur le treeview.items.add :(

TreeView ou TreeListView multicolonne

Bonjour mso54
Dans la continuite de ce que recommende GuruuMeditation pour la structure de ta classe Player ,voici un code complete pour l'utilisation du Custom Control TreeViewList de la SDK MSDN fr (voir lien à la fin):
le custom control MSDN que j'ai mis dans Application.Resources a ete modifie comme suit:
1/La collection GridViewCollection designe par la cle "gvvcc" a ete modifie pour etre lie aux champs PlayerScore et LstType de la classe Player.

2/le DataTemplate du modele cellule de la la 1ere colonne de la collection GridViewCollection designe par la cle "CellTemplate_Name a ete lie à la prop PlayerName de la classe Ligue.

Lien MSDN(titre TreeListView Sample):

http://www.google.fr/url?sa=t&rct=j&...zjHEx6L28WGpTw

N.B.: l'original MSDN donne un exemple d'utilisation que j'ai trouve tres bizarre pour une fois car il utilise comme "data" les classes du .Net FrameWork....

Enfin ce qui m'as intrigue c'est d'ou tu as "recupere" le sample(on dirait l'original MSDN trituré par quelqu'un d'autre.......)....
Bon code................

A vrai dire je sais plus trop où je l'ai trouvé, c'était sur un forum anglais et la personne qui a posté les sources l'avait récupéré ailleurs.... J'essayerai de retrouver la source quand je serai chez moi car la je suis au boulot ^^
Après qu'il l'ait trituré ou pas m'importe peu du moment que cela fonctionne ^^

Sinon je ne suis pas sur que je peux appliquer cet exemple.
J'ai simplement une collection d'une seule classe qui elle même contient une collection. Si cela fonctionne pour le premier noeud de mon treeview(j'ai bien mes 2 niveaux), il doit y avoir moyen de créer d'autres noeuds.
Enfin je vais tester et on verra ;)

Je viens d'essayer ca marche bien seul hic (Et oui y'en a toujours un :(),
Le niveau 1 est vide, cad :
Code:

1 2 3 4 5 6 7 8 9 10 11 12 + (Vide) + PlayersXX Score ListTyp Score ListTyp Score ListTyp Score ListTyp + PlayersXX Score ListTyp Score ListTyp Score ListTyp Score ListTyp
Les "+" correspondant au expander

le niveau 1 manque

bonjour mso54
ben oui c'est fait express dans ce semblant (a custom view that resembles the GridView view mode that is used by ListView) de "custom treeview" de microsoft comme ils disent
Le presenter du TreeView "normal" sert à contenir une prop Header (header de titre) definie dans le TreeViewListView "normal" .
Ce presenter du TreeView est "squatte" maintenant par l'en-tete du "gvcc" ( GridViewColumn) qu'on a rajoute.
code xaml de appl.resources auquel je fais allusion:

 <Style 
            TargetType="{x:Type local:TreeListViewItem}">
            <Setter 
                Property="Template">
                <Setter.Value>
                    <ControlTemplate 
                        TargetType="{x:Type local:TreeListViewItem}">
                        <StackPanel>
                            <Border 
                                Name="Bd"
                                Background="{TemplateBinding Background}"
                                BorderBrush="{TemplateBinding BorderBrush}"
                                BorderThickness="{TemplateBinding BorderThickness}"
                                Padding="{TemplateBinding Padding}" >
                               'ici ou le bat blesse
                               <GridViewRowPresenter 
                                    x:Name="PART_Header" 
                                    Content="{TemplateBinding Header}" 
                                    Columns="{StaticResource gvcc}"/>  
                            </Border>
                            <ItemsPresenter 
                                x:Name="ItemsHost"/> 
                        </StackPanel>

pour t'en convaincre encore mieux fais ceci:
-mets la classe sur un TreeView normal.
-mets la prop Header du treeviewItem à "Derby des champions des Champions".Observe la presentation du Header.
Fais de meme avec la prop Header du Custom TreeListView.
Le xaml compile mais à l'execution rien ne s'affiche...car la prop est squattee..
bon code.............

Si j'ai bien compris, je suis obligé de laisser cette première ligne vide ? xD

bonjour mso54
Suite à ta question sur l'entete j'ai du revoir le "sample" de plus pres.
Le "sample" affiche effectivement le "Nom" du class "binde" (qui est un DependencyObject comme suggere par l'intellisense).
L'astuce c'est de mettre notre type Ligue "binde" .
Et affecter une simple valeur chaine à la prop PlayerName du type Ligue comme titre du Header du TreeListViewItem.
Tu le fais sous la baslise <local:TreeListViewItem.

voici le code xaml modifie :
