如何WPF TreeView控件绑定到一个List＆LT;饮料＆GT;编程？ [英] How to bind WPF TreeView to a List<Drink> programmatically?

问题描述

所以，我很新的WPF和试图绑定或饮料值的列表分配到一个WPF树视图，但不知道该怎么做，并发现它真的很难在网上找到任何东西，只是显示的东西，而使用XAML。

So I am very new to WPF and trying to bind or assign a list of Drink values to a wpf treeview, but don't know how to do that, and find it really hard to find anything online that just shows stuff without using xaml.

struct Drink
{
    public string Name { get; private set; }
    public int Popularity { get; private set; }

    public Drink ( string name, int popularity )
        : this ( )
    {
        this.Name = name;
        this.Popularity = popularity;
    }
}

List<Drink> coldDrinks = new List<Drink> ( ){
    new Drink ( "Water", 1 ),
    new Drink ( "Fanta", 2 ),
    new Drink ( "Sprite", 3 ),
    new Drink ( "Coke", 4 ),
    new Drink ( "Milk", 5 ) };
        }
    }

我怎样才能做到这一点在code？例如：

How can I do this in code? For example:

treeview1.DataItems = coldDrinks;

和一切都显示在树视图。

and everything shows up in the treeview.

推荐答案

您可以只设置：

treeView1.ItemsSource = coldDrinks;

不过，我怀疑这里使用一个TreeView的。你显然呈现出平整，无分层数据，因此没有理由用一个TreeView。

However, I question the use of a TreeView here. You're obviously showing flat, non-hierarchical data, so there is no reason to use a TreeView.

为什么不直接使用一个ListView或列表框？

Why not just use a ListView or ListBox?
