Bind Dictionary to ItemsControl in C#/WPF
提问by Joseph jun. Melettukunnel
I'm trying to bind KeyValuePair Elements from a Dictionary to a ItemsControl. My Dictionary has 15 Elements and the following code shows me 15 TextBoxes:
我正在尝试将字典中的 KeyValuePair 元素绑定到 ItemsControl。我的字典有 15 个元素，下面的代码显示了 15 个文本框：
<WrapPanel Name="PersonsWrapPanel" Grid.Row="0">
<ItemsControl ItemsSource="{Binding Persons}" >
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel Orientation="Horizontal" Width="auto">
</WrapPanel>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<TextBox Text="{Binding Value.Text}"></TextBox>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</WrapPanel>
Unfortunately without any TextBox content (which would be Key or Value). Any ideas?
不幸的是没有任何文本框内容（这将是键或值）。有任何想法吗？

I solved it by using this line:
我通过使用这一行解决了它：
<TextBox Text="{Binding Value, Mode=OneWay}"></TextBox>
The code on http://www.dev102.com/2008/03/07/binding-a-wpf-control-to-a-dictionary/doesn't seem to work.
http://www.dev102.com/2008/03/07/binding-a-wpf-control-to-a-dictionary/上的代码似乎不起作用。

Perhaps try binding directly to the values of the dictionary:
也许尝试直接绑定到字典的值：
ItemsSource="{Binding Persons.Values}"
If I am understanding your XAML properly, each object in the dictionary has a field called "Text" to which you are trying to bind. If so and you make the above changes, you will need to change your DataTemplate as well:
如果我正确理解您的 XAML，字典中的每个对象都有一个名为“文本”的字段，您正试图绑定到该字段。如果是这样并且您进行了上述更改，则还需要更改您的 DataTemplate：
<TextBox Text="{Binding Text}" />

Let us say you have a Dictionary called RowValues, with both the [key, value] defined as [string, string].
假设您有一个名为 RowValues 的字典，其中 [key, value] 都定义为 [string, string]。
Now to bind to the Value Pair of this dictionary, you can do the following:
现在要绑定到此字典的值对，您可以执行以下操作：
<ItemsControl ItemsSource="{Binding RowValues.Values}" >
To display the text (Value), you can bind as:
要显示文本（值），您可以绑定为：
<TextBlock Text="{Binding}"/>
