在我的例子中我綁定到一個ListBox的selectedItem。我想知道如何設置堆棧面板中的綁定,所以我不必然後單獨綁定到每個控件。wpf綁定到selectedItem
我可以只綁定堆棧面板,然後將子控件只得到約束,像這樣(僞代碼)
<StackPanel Grid.Column="2" Content="{Binding SelectedItem.Name, ElementName=ItemList}"/>
<TextBox Text="{Binding Name, UpdateSourceTrigger=PropertyChanged}"/>
<TextBox Text="{Binding Kids, UpdateSourceTrigger=PropertyChanged}"/>
<TextBox Text="{Binding Age, UpdateSourceTrigger=PropertyChanged}"/>
</StackPanel>
代碼
<ListBox Grid.Column="0"
x:Name="ItemList"
Background="AliceBlue"
ItemsSource="{Binding VNodes}"
SelectedItem="{Binding SelectedVNode, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}">
<ListBox.ItemTemplate>
<DataTemplate>
<WrapPanel>
<TextBlock Text="Name: " />
<TextBlock Text="{Binding Name}" FontWeight="Bold" />
</WrapPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<GridSplitter Grid.Column="1" Width="5" HorizontalAlignment="Stretch" />
<StackPanel Grid.Column="2">
<TextBox Text="{Binding SelectedItem.Name, ElementName=ItemList, UpdateSourceTrigger=PropertyChanged}"/>
<TextBox Text="{Binding SelectedItem.Kids, ElementName=ItemList, UpdateSourceTrigger=PropertyChanged}"/>
<TextBox Text="{Binding SelectedItem.Age, ElementName=ItemList, UpdateSourceTrigger=PropertyChanged}"/>
</StackPanel>
