我有一个自定义的TreeView,如下所示:
----------------------------
| ---------------------- |
| | | |
| ---------------------- |
| ---------------------- |
| | | |
| ---------------------- |
| ---------------------- |
| | | |
| ---------------------- |
| |
---------------------------
---------------------------
| |
---------------------------
' - '是边界的边界。我已经删除了>扩展TreeView。另外,我已经做到了,所以TreeView总是被扩展。
父结构将托管边框内的所有TreeView项目,并且每个TreeView项目也将获得自己的边框。
我正在使用其他两个类继承的基础Team类。这两个继承的类使用HierarchicalDataTemplate来填充TreeView项。
我想做什么:
我的团队课程如下所示:
public abstract class Team
{
public string Name { get; set; }
public string Division { get; set;
}
我想要做的是将Division属性放在TreeView中,使它看起来像:
----------------------------
| ---------------------- |
| | | |
| ---------------------- |
| first blocks Division |
| ---------------------- |
| | | |
| ---------------------- |
| second blocks Division |
| ---------------------- |
| | | |
| ---------------------- |
| third blocks Division |
| |
---------------------------
main big Blocks Division
---------------------------
| |
---------------------------
smaller second Block's Division
因此,Division属性将位于TreeView的边界之外。
这是继承自团队
的两个类DoubleA:
public class DoubleA : Team
{
public DoubleA()
{
this.Players = new ObservableCollection<string>();
}
public ObservableCollection<string> Players { get; set; }
}
}
SingleA:
public class SingleA : Team
{
public SingleA()
{
this.Affiliations = new ObservableCollection<Team>();
}
public ObservableCollection<Team> Affiliations { get; set; }
在我的主视图模型中,我使用Organization类来填充我的数据:
public class Organization
{
public Organization()
{
this.TopSingleA = new SingleA();
}
public SingleA TopSingleA { get; set; }
}
}
这是我的主视图模型中填充TreeView的方法:
public class MainViewModel : NotifyPropertyChanged
{
public MainViewModel()
{
this.Organization = new Organization { Name = "Major League Baseball "};
this.PopulateView();
}
private Organization organization;
public Organization Organization
{
get
{
return this.organization;
}
set
{
this.organization = value;
OnPropertyChanged("Organization");
}
}
public void PopulateView()
{
SingleA advanced = new SingleA { Name = "Advanced A" };
SingleA rookieLeague = new SingleA { Name = "Rookie League" };
DoubleA player1 = new DoubleA { Name = "Tim Tebow" }; rookieLeague.Affiliations.Add(player1);
DoubleA player2 = new DoubleA { Name = "Michael Jordan" }; rookieLeague.Affiliations.Add(player2);
DoubleA player3 = new DoubleA { Name = "Bo Jackson" }; rookieLeague.Affiliations.Add(player3);
DoubleA player4 = new DoubleA { Name = "Russell Wilson" };
advanced.Affiliations.add(rookieLeague);
advanced.Affiliations.add(player4);
this.Organization.TopSingleA = advanced;
}
}
