Please show us how you build your collection and what the class looks like.
PartsList seems an odd name for a class but whatever contains your VendorPartNoLink etc.
One thing I'm particularly interested to see is whether it has a collection within it or you're just kind of expecting it to work out what the children are.
Because it won't.
You need something like a converter on your binding.
Like here:
http://stackoverflow.com/questions/14161963/how-to-bind-self-referencing-table-to-wpf-treeview
<TreeView Name="treeview1" ItemsSource="{Binding Converter={StaticResource HierarchyConverter}}" ItemTemplate="{StaticResource ItemTemplate}" ><TreeView.Resources><local:HierarchyConverter x:Key="HierarchyConverter" /><HierarchicalDataTemplate x:Key="ItemTemplate" ItemsSource="{Binding Converter={StaticResource HierarchyConverter}}"><TextBlock Text="{Binding element_name}" /></HierarchicalDataTemplate></TreeView.Resources></TreeView>And that converter gets the children:
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
var item = value as MyTable;
return item.MyTable1.Where(i => i.parent_id== item.id); //return children
}Personally, I prefer to translate into an object containing a child collection.
One of these presents units. A unit can have subunits each subunit contains a unit... and so on.
My itemtemplate presents a unit and the hierarchicaldatatemplate looks:
<HierarchicalDataTemplate
ItemsSource="{Binding Path=Unit.SubUnits}"
DataType="{x:Type model:SubUnit}"In Unit:
private ObservableCollection<SubUnit> _SubUnits;
public ObservableCollection<SubUnit> SubUnits
{
get
{
if (_SubUnits == null)
_SubUnits = new ObservableCollection<SubUnit>();
return _SubUnits;
}
set { _SubUnits = value; }
}SubUnit has a few properties like a GUID and
public Unit Unit
{
get
{
return _Unit;
}
set
{
_Unit = value;
OnPropertyChanged("Unit");
}
}
