just starting with wpf. I need to bind the object (Hierarchical) Folder
public class Folder
{
public Folder()
{
this.Name = string.Empty;
this.Modules = new ObservableCollection<Module>();
this.Folders = new List<Folder>();
this.HasChild = false;
}
public Folder(Folder parent)
{
this.Name = string.Empty;
this.Modules = new ObservableCollection<Module>();
this.Folders = new List<Folder>();
this.HasChild = false;
this.Parent = parent;
}
public bool HasChild { get; set; }
public string Name { get; set; }
public List<Folder> Folders { get; set; }
public ObservableCollection<Module> Modules { get; set; }
public Folder Parent { get; set; }
public Folder IfItemExists(string name)
{
foreach (Folder folder in Folders)
{
if (folder.Name == name)
{
return folder;
}
}
return null;
}
}
to the treeview. I am doing like that
<TreeView Name="treeView" Margin="5">
<TreeView.ItemTemplate>
<HierarchicalDataTemplate ItemsSource="{Binding Path=Folders}" DataType="{x:Type ModulesUpToDateChecker:Folder}">
<HierarchicalDataTemplate.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Path=Name}"></TextBlock>
</DataTemplate>
</HierarchicalDataTemplate.ItemTemplate>
</HierarchicalDataTemplate>
</TreeView.ItemTemplate>
</TreeView>
and have just empty docpanel. The object is filled write. Eche child has own child with the same Type.
A HierarchicalDataTemplate is already a DataTemplate (it derives from it). So just skip the ItemTemplate and DataTemplate stuff inside your HierarchicalDataTemplate like so:
<TreeView Name="treeView" Margin="5">
<TreeView.Resources>
<HierarchicalDataTemplate ItemsSource="{Binding Path=Folders}" DataType="{x:Type WpfApplication220:Folder}">
<TextBlock Text="{Binding Path=Name}"></TextBlock>
</HierarchicalDataTemplate>
</TreeView.Resources>
</TreeView>
Oh and you have to set the ItemsSource of your treeview either programmatically or in your markup ..
treeView.ItemsSource = ..yourFolderList..
