WPF 绑定方式举例

WPF 绑定方式举例

一、如果ItemsControl 控件的ItemsSource要绑定到List类型，可以如下：

List<string> Names = new List<string>();
Names.Add("aaa");
Names.Add("bbb");

<ItemsControl ItemsSource="{Binding Student}" VerticalAlignment="Center">
    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <StackPanel Orientation="Horizontal"/>
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <TextBox Text="{Binding .}" Width="60" Height="22" Margin="0 0 10 0"/>
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</ItemsControl>

二、ItemControl的子项怎么绑定与父项同一级的属性，如下：

<ItemsControl ItemsSource="{Binding YourCollection}">
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <!-- 绑定到与ItemsControl同一级别的属性 -->
            <TextBlock Text="{Binding 
                RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}, 
                Path=DataContext.YourProperty}"/>
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</ItemsControl>

三、ItemsControl中的子项的按键如何绑定与父项同一级的事件，如下：

<ItemsControl ItemsSource="{Binding YourCollection}">
    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <StackPanel Orientation="Horizontal"/>
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <Button Command="{Binding DataContext.TextChangedCommand,RelativeSource={RelativeSource Mode=FindAncestor,AncestorType=ItemsControl}}"/>
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</ItemsControl>
