绑定到字典值中的对象 [英] Binding to object in dictionary value

问题描述

我有一个关键Guid和网络类值的字典，我希望将ItemsControl项绑定到Dictionary中的Network类



这是xaml我有。

I have a dictionary of key Guid and a network class value, and I wish to bind the ItemsControl Items to the Network classes inside the Dictionary

Here is the xaml I have.

<ItemsControl ItemsSource="{Binding NetworkList}" x:Name="iclItems" Grid.Column="1" Grid.Row="1">
            <ItemsControl.ItemTemplate>
                <DataTemplate>
                    <Grid removed="Orange" Width="250" Height="250" Margin="20">
                        
                    </Grid>
                </DataTemplate>
            </ItemsControl.ItemTemplate>
            <ItemsControl.ItemsPanel>
                <ItemsPanelTemplate>
                    <WrapGrid Orientation="Horizontal" />
                </ItemsPanelTemplate>
            </ItemsControl.ItemsPanel>
        </ItemsControl>

这里的代码背后只添加一个网络到字典< br $> b $ b

And here is the code behind that adds just a Network to the dictionary

private Dictionary<Guid, Network> mdictNetworkList;
public Dictionary<Guid, Network> NetworkList
{
    get { return mdictNetworkList; }
    set { mdictNetworkList = value; }
}
public MainPage()
{
    this.InitializeComponent();

    mdictNetworkList = new Dictionary<Guid, Network>();
    Network objNetwork = new Network();
    mdictNetworkList.Add(objNetwork.ID, objNetwork);
}

我没有收到任何物品。有什么想法吗？如果之前有人问过这个问题我很抱歉，但是我无法找到解决问题的答案。

I''m not getting any items being added. Any ideas why? I''m sorry if this has been asked before, but I couldn''t find an answer to my problem that worked.

推荐答案

当<$的值时c $ c> NetworkList 正在改变然后你没有解雇 RaisePropertyChanged 事件

例如

When the value of NetworkList is changing then you are not firing RaisePropertyChanged event
e.g.

this.RaisePropertyChanged("NetworkList");

以及您在代码中绑定DataContext的位置？

and where you are binding the DataContext in your code?

this.DataContext = this;
